High heat resistant / Flame-Retardant Series

This series realizes high heat resistance while maintaining high performance such as high sealing performance, vibration-absorbing property, and dimensional stability, which are characteristic of PORON.

  • TR
    • strong_ic_01_en

    This highly heat-resistant type achieves overwhelmingly low compression set at a high temperature range (70℃-110℃). Even at room temperature, it delivers more stable performance.

  • RX
    • strong_ic_01_en

    RX is a high flame retardant and halogen free grade which acquires UL94 V-0 standard.

  • ATR
    • strong_ic_05_en
    • strong_ic_01_en

    ATR is an excellent sealing material with heat resistance and high durability. Special surface PR type can seal surface leakage.

※The figures all indicate representative values.
※The *1 mark of 25% compressive load is 40% compressive load, the *2 mark is 10% compressive load and the *3 mark is 50% compressive load.
※The *4 mark of compression set is a measurement taken using a test method with a 25% compression rate.
※The measurement method is our test method based on JIS standard.
