TENAC™  Grade Table

Asahi Kasei is proud to offer an extensive lineup of both homopolymer (TENAC™) and copolymer (TENAC™-C) grades with varying viscosities. 

More specifically, for both homopolymer and copolymer resins we offer the following grade categories: standard grades, low-VOC grades, high-cycle grades, weather-resistant grades, filler-reinforced grades, and sliding grades. For homopolymer resins we additionally offer high-durability grades and soft grades. For copolymer grades we additionally offer HC grades—which combine the mechanical strength of homopolymers with the chemical resistance of copolymers—as well as electrically-conducting grades and various other highly functional grades. 

We also offer other types of grades, including grades intended for use as binder resins in powder injection molding (PIM) and  grades featuring metallic tints. Please contact us to discuss these options in further detail.

High-durability grades

Corresponding grades

These grades are specifically designed for maximal performance when used to construct gears and other components required to exhibit high durability (including sliding behavior, fatigue behavior, and creep resistance) under high-load, high-torque conditions. They have been widely adopted for applications primarily in the automotive domain, where they offer promising potential as replacement materials for metallic components to achieve lightness in weight.

Product Data/Tips for Use *Handling Precautions

Precautions for handling TENAC™

The content of this document is based on currently available materials, information and data, and may be revised based on new findings. Please note that these are provided as information and are not guaranteed. Therefore, when using our products, please give full consideration to the usage environment, design, etc., and use them at your own risk after judging that there is no problem with the product.

1. Handling Precautions

We have prepared a separate "Product Safety Data Sheet" regarding precautions for handling TENAC™, so please read it before using TENAC™. The following points are important points when handling TENAC™. Please use it for safe handling of TENAC™. Please investigate the safety of pigments, additives, etc. that your company uses other than those specified by Asahi Kasei TENAC™ and their compatibility with TENAC™.

(1) Safety and health precautions
The main component of the gas generated when TENAC™ is dried, melted, and decomposed is formaldehyde. Take care to avoid contact with eyes, skin, and inhalation. Also, avoid touching the high temperature resin directly. For each work such as drying and melting, it is necessary to install a local exhaust system and wear protective equipment (safety glasses, protective gloves, etc.).

(2) Precautions regarding combustion
TENAC™ is flammable and should be handled and stored away from heat and sources of ignition. If it burns, it may generate toxic gas. Water, foam, and dry powder can be used to extinguish the fire.

(3) Precautions for disposal
TENAC™ can be disposed of by landfill or incineration, but please entrust it to an authorized industrial waste disposal company or local government in accordance with the "Waste Disposal and Public Cleansing Act." In addition, when incinerating it yourself, please use incineration equipment and process in accordance with various laws and regulations such as the Air Pollution Control Act. When incinerated, toxic gas may be generated.

(4) Notes on storage
It is a combustible material (synthetic resins) designated by the Fire Service Act, and should be handled in accordance with municipal ordinances. (fire extinguishing equipment, indoor storage facilities, etc.)

(5) Notes on molding
Please pay attention to the following points to avoid decomposition of the resin.・Do not allow the resin to remain in the processing machine for a long time at high temperatures.・Do not mix extrusion with strong acids, oxidizing agents, or PVC. Pellets, etc. spilled on the floor may slip under your feet and cause a fall if left unattended, so please clean and remove them immediately.

2. Usage

  • ・Do not use TENAC™ for implantation into the body or for direct contact with body fluids or infusions. When using this product for other medical purposes, please be sure to contact our representative in advance.
  • ・When using TENAC™ in applications where it comes into direct contact with food, please select a grade that complies with the Polyhyeikyo PL (Positive List), Food Sanitation Law, and FDA. In that case, please be sure to contact our representative in advance.
  • ・When using TENAC™, be sure to evaluate the physical properties, durability etc. of the actual product in advance.

3. Others

Please be aware of industrial property rights, etc. when using this product.
