What are XYRON™ DG series and XP series?

XYRON™'s PPS/PPE alloys DG series and PPA/PPE alloys XP Series are high-performance grades with excellent heat resistance, electrical properties, and dimensional stability. While based on the properties of PPS and PPA, which are super engineering plastics, they have unique characteristics by adding the properties of PPE resin.

XYRON™ DG series and XP series characteristics

XYRON™ DG series : Excellent dimensional properties, Outstanding moldability with no flash

Polyphenylene sulfide (PPS) resin is a super engineering plastic with excellent heat resistance, low- Coefficient of Linear Thermal Expansion (CLTE), excellent chemical resistance, and flame retardance. PPS resin is expanding in applications in automotive, electronics, electrical parts, and water supply and drainage applications.

XYRON™ DG series (PPS and PPE alloys) boast improved dimensional stability and excellent injection moldability, with low warping or burr formation, compared with super engineering plastics PPS. CLTE of PPS/PPE alloys is stable over a wide temperature range, and these alloys offer stable mechanical properties even at high temperatures. Alloying with PPE yields materials with exceptional electrical properties, enhancing your freedom in designing high-frequency devices.

XYRON™ XP series: Excellent mechanical properties and lower dimensional change under high temperatures and humidity

Polyphthalamide (PPA) resin is a super engineering plastic with excellent heat resistance compared with aliphatic polyamides (PA, nylon), which has good chemical resistance, and strength. PPA resin is also expanding in applications in automobiles, electronics, and electrical parts.

Alloying PPE and special PPA, which exhibit lower water absorption and higher heat resistance, even compared to other PPA, stand out for their high strength, low water absorption, and high dimensional stability, even in high-humidity, high-temperature environments.

Product Data/Tips for Use *Handling Precautions

Precautions for using XYRON™ (modified polyphenylene ether resin)

<Caution>
The content of this document is based on currently available materials, information and data, and may be revised based on new findings. In addition, since the precautions are intended for normal handling, in the case of special handling, please use after implementing safety measures suitable for the application and usage.

1. Handling Precautions

The key points for handling XYRON™ are shown below. Please use them to ensure safe handling of XYRON™. Safety data sheets have been created separately for handling precautions for each grade of XYRON™. Please read the safety data sheets before use. We ask that you investigate the safety of any additives other than XYRON™ that you use yourself.

A. Precautions during operation
When handling XYRON™, be careful to avoid contact with or inhalation of pellets, molten resin, or gases generated during melting. In the unlikely event that contact or inhalation occurs, the first aid measures are as follows:

  • ・If it gets into your eyes
    If it gets in your eyes, rubbing it may cause irritation or damage the cornea, so wash thoroughly with clean water for at least 15 minutes without rubbing, and if there are any abnormalities, seek medical attention.
  • ・If it adheres to the skin
    In general, wash with water or soap, and if molten material adheres, immediately cool with clean water. Do not forcibly peel off the hardened resin on the skin, and seek medical attention.
  • ・If inhaled
    Normally, there is no direct effect on the human body, but if you inhale dust, etc., gargle well with clean water. If breathing fumes from the melt makes you sick, move to fresh air and wait for recovery. If it does not recover, get medical attention.
  • ・If swallowed
    Spit it out as much as possible, and if there are any abnormalities, seek medical attention.

B. Safety and Health Precautions
Be careful to avoid eye or skin contact and inhalation of gases generated during drying and melting of XYRON™. Also, do not directly touch hot resin. When drying and melting, it is necessary to install local exhaust ventilation and wear protective equipment (protective glasses, protective gloves, etc.).

  • ・Equipment measures
    In the molding work, there is a risk that gas may be generated by heating and melting, so please install an effective local exhaust system etc.
  • ・Respiratory protective equipment
    Wear a mask for organic gas when working in a place where there is a possibility of inhaling generated gas or fume. Wear a dust mask when working with resin products, sanding, or other work that generates dust.
  • ・Protective glasses
    When working, wear resin safety glasses with side seals, resin goggles, etc.
  • ・Protective gloves
    Wear as needed. In particular, when handling molten resin, use gloves with good heat insulation to prevent burns.
  • ・Protective clothing
    Regular work clothes are fine, but especially when handling molten resin, wear long-sleeved clothing to prevent burns.
  • C. Combustion Precautions
    XYRON™ is flammable, so handle, transport, and store it away from heat and sources of ignition. In the event of a fire, it may produce intense heat, black smoke, carbon dioxide gas, carbon monoxide gas, and other toxic gases. To extinguish a fire, the same extinguishing agents as for general fires, such as water, foam extinguishing agent, or powder extinguishing agent, can be used. When extinguishing a fire, wear fireproof clothing and breathing equipment.

    D. Precautions for transportation
    Avoid getting wet and rough handling to prevent the packing bag from tearing. In the unlikely event that the bag is broken and the pellets are scattered, take special care not to slip and fall, and quickly sweep up and collect or dispose of them. Take measures to prevent static electricity disasters during pneumatic transportation.

    E. Storage Precautions
    Store XYRON™ in a location away from direct sunlight, high temperatures, and high humidity. Store it away from heat and sources of ignition, and take measures to prevent static electricity hazards.

    F. Disposal Considerations
    XYRON™, follow the Waste Disposal and Public Cleansing Law and entrust the disposal to a certified industrial waste disposal company or to a local government organization if such organization is in charge of disposal. When disposing of ZYLON™, use an incineration facility and dispose of the material in accordance with the Air Pollution Control Law and other laws and regulations.

    2.Regarding conforming standards

    XYRON™ has grades that comply with the voluntary regulations for polyolefin and other synthetic resin food containers and packaging, Ministry of Health, Labor and Welfare Notification No. 370, UL, CSA, and Electrical and Electronics Control Law. Please contact our staff for details.
