OA equipment is an abbreviation for Office Automation, and is a general term for information equipment for companies that makes office work more comfortable, and includes printers, personal computers, projectors, shredders, etc. Printer is a general term for printing machines, and OA equipment printers mainly refer to multifunction machines and multifunction printers that have fax, copy (copy), and scan functions. This printer has various printing methods (methods of transferring information to an object such as paper). The printing methods of printers can be broadly divided into two types: impact methods and non-impact methods.
We introduce the modified PPE resin XYRON™, which is used for printer internal chassis and ink head peripheral parts, and the POM resin TENAC™, which is used for various gears, mechanical parts, conductive bearings.

What is XYRON™?
XYRON™ is a general term for polymer alloys of polyphenylene ether (PPE) and other resins.
The XYRON™ family, which Asahi Kasei has been producing since 1979, boasts an extensive track record—occupying a key role in the history of engineering plastics—and today encompasses an extensive lineup of polymer alloys.
XYRON™ has several outstanding properties. In addition to having high heat resistance, it also has excellent flame resistance, insulation, dimensional stability, and water resistance, as well as low specific gravity. Furthermore, it is a polymer alloy material that aims to create a synergistic effect with the characteristics of PPE by adding PPE while also taking advantage of the characteristics of other resins. For example, it can be used for high-precision parts with a high degree of design freedom suitable for housings, interior chassis, and mechanical parts.
XYRON™ recycled grade for sustainability
Asahi Kasei is working to develop recycled XYRON™ grades that combine PPE with various recycled resins to yield sustainable manufacturing without sacrificing the high performance of these unique materials. This recycled grade of XYRON™ allows up to 40% post-consumer recycled resin utilization. In addition, based on the concept of local production for local consumption, we aim to procure recycled resin from each processing plant, and in addition to reducing our carbon footprint, we have established a system that pays attention to BCP and logistics.
We are also developing a new alloy recycling system that utilizes PCR resin. We are also looking for partners for closed schemes that enable closer development with customers.
XYRON™ DG series is a revolutionary material that retains the characteristics of PPS, which is a crystalline resin, and PPE, which is an amorphous resin, while significantly improving the shortcomings of each.
The characteristics of this material are as follows.
heat resistance: It has very high heat resistance, close to that of super engineering plastics.
mechanical properties: Excellent balance of strength and stiffness. It also maintains high stiffness even in high temperature environments.
flame resistance: A high flame retardant level without the use of flame retardants.
Dimensional accuracy and dimensional stability: Since the anisotropy due to orientation is small, it is possible to manufacture products with little warpage.
Oil and chemical resistance: Excellent oil and chemical resistance.
Molding workability: It is possible to improve the "burr" that is a problem in molding PPS resin.
Low specific gravity: Compared to PPS resin, the specific gravity is significantly lower. Therefore, the weight of parts can be reduced.

What is TENAC™?
Polyacetal (POM) has excellent mechanical properties, sliding properties, and chemical resistance, so it is used in many mechanical and interior parts. As the world's only company and product that manufactures and sells homopolymers and copolymers, Asahi Kasei 's POM resin TENAC™ has a proven track record in a variety of applications and materials. The copolymer `` TENAC™ -C'' is manufactured and sold at a plant in Japan as well as in Zhangjiagang, China.
TENAC™ -C NS556, which realizes high-stiffness and high-precision gears
TENAC™ -C NS556 is a next-generation compound material that achieves both high stiffness and high precision, which have been difficult until now, as well as durability. The features of TENAC™-C NS556 are as follows.
Excellent dimensional accuracy and stability: It can be expected to improve the static accuracy, roundness, and boss cylindricity of gears that require dimensional stability and accuracy, as well as the dynamic accuracy required during actual use. This effect is expected especially for large-diameter gears and helical gears.
Both high stiffness and durability: While exhibiting an elastic modulus of about 150% compared to general copolymers, it is a material that also has durability.
Excellent warpage resistance: It is possible to reduce warpage in thin-walled or uneven-walled molded products, and to suppress boss collapse and core deflection. It is also effective in suppressing sink marks on molded products.
High thermal stiffness: The deflection temperature under load is 124°C (1.8 MPa load). As a result, it is possible to shorten the cycle during molding.
TENAC™ -C TFC77, EF850 is a conductive material that replaces metals used for grounding and contacts, reducing costs by integrating parts and eliminating secondary processing steps.
TENAC™ -C TFC77 is a grade that combines high conductivity and sliding properties by using two types of special carbon in polyacetal resin and at the same time blending a lubricant that does not inhibit conductivity. The features of TENAC™-C TFC77 are as follows.
Excellent conductivity with a volume electric resistance value of 10 0 to 10 1 Ωcm.
A smooth molding surface is possible, realizing a stable electrical resistance value.
By adding sliding properties, it shows a stable electrical resistance value even during operation and after stopping.
In addition, TENAC™ -C EF850 is based on highly fluid polyacetal resin, and is designed with special carbon black to prevent static electricity.It has good conductivity and high fluidity (MFR: 15 g/10min (190℃, This is a grade that achieves both 2.16kg load)).
Printer has various printing methods (methods of transferring information to an object such as paper). The printing methods of printers can be broadly divided into two types: impact methods and non-impact methods.
Types of non-impact methods
There are four major non-impact methods that are widely used in today's society: the inkjet method, the dry electrophotographic method, the thermal method, and the thermal transfer method. Among these, the inkjet method and the dry electrophotographic method are particularly widespread.
The inkjet method is a method that ejects fine particles of ink from the printer head by applying pressure to the ink. High image quality can be achieved by miniaturizing the nozzles of the printer head and using multicolor ink. It can be divided into the piezo method and the thermal method according to the method of applying pressure to the ink. The piezo method uses a piezo element that deforms when voltage is applied. A piezo element is attached to a fine tube containing ink, and by applying a voltage to the piezo element and deforming it, the ink is ejected out of the tube. In the thermal method, the ink is boiled by heating with a heater, and the ink is ejected by the bubbles that are created. A stack of these ink ejection mechanisms is called an ink head or print head. The ink supplied from the ink tank inside the ink cartridge is applied to the paper and other printing media. As a printer mechanism, the method of printing by reciprocating the ink head in the direction perpendicular to the movement of the print medium is called the "serial head method", and it is a general mechanism that is also used for home use. On the other hand, there is also the "line head method," in which the ink head is extended and fixed to the same length as the print medium, and printing is performed only by the movement of the print medium without the head moving. This method is used for commercial and industrial printing of posters, labels, etc., because it can print clearly at high speed. The ink used in the inkjet method is water-based ink, which is mainly divided into pigment ink and dye ink. The subtractive color method is used to express other colors by mixing cyan (C), magenta (M), and yellow (Y). It is In general, pigment ink has the advantage of being water- and light-resistant, and does not bleed or change color after printing. Dye inks have the opposite characteristics of pigment inks: they have high color reproducibility, are easy to produce gloss, and dry quickly, but their water resistance and light resistance are low, and color fluctuations after printing can be large. considered a shortcoming.
Dry electrophotographic method
This is commonly known as a “laser printer” or “laser beam printer (LBP)”. In this method, a laser beam or the like is used to irradiate a charged photoreceptor (drum) with the content to be printed, which causes pigment powder (toner) to adhere to it, transfer it to paper, and apply heat and pressure to fix it. In addition to lasers, light emitting diodes (LEDs) may also be used, in which case they are called "LED printers." It is mainly used for business use, and many business use copiers (copiers, PPC copiers) also use this method. It is also called a "page printer" because it prints one page at a time instead of printing one line at a time.
Thermal printing is a printing method that presses a print head (thermal print head) heated by an electric current against a special paper (thermal paper) that changes color when heat is applied. Also called a direct thermal printer. It is used for cash register receipt printers and label printers that are active in food labeling and distribution label printing.
Thermal transfer method
It is similar to the thermal method, but instead of thermal paper, it is a printing method in which a thermal print head is pressed against an ink ribbon coated with ink, and the ink is transferred to the paper by heat. Also called a sublimation printer. It is used in home FAX printers, etc.
Type of impact method
There is a "dot impact method" in the impact method.
Dot impact method
Method In this method, a thin pin corresponding to the dot (point) is placed on the paper and hits (impact) an ink ribbon (a band-shaped film coated with ink), and the character is expressed by a group of dots. It's not a printer, but the principle is similar to the old typewriters. With the spread of laser printers and inkjet printers, dot printers have disappeared from general printing applications. This method is still widely used for printing.
Printer Market Overview and Trends
According to the JEITA Information and Industrial Systems Working Group , the global printer market in 2019 was 98.51 million units (93% of the previous year). The market for general consumers is considered to have reached maturity, and there are areas where the market is shrinking due to the spread of smartphones and the progress of various digitalizations.
On the other hand, we are expanding our solution business for large companies, such as MPS (Managed Print Service), and incorporating commercial and industrial printing as a growth area, where digitalization is progressing.
Representative environmental labels from around the world
As a conventional trend, there is the acquisition of environmental label (eco-label) certification system.
