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
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
RX is a high flame retardant and halogen free grade which acquires UL94 V-0 standard.
ATR
ATR is an excellent sealing material with heat resistance and high durability. Special surface PR type can seal surface leakage.

Features

Flame-Retardant
Excellent flame retardancy

We have non-halogen ultra-high flame retardant grades (RX) that have acquired UL-94 V-0 as polyurethane foam.
High heat resistance
TR and ATR achieve overwhelmingly low compression set at a high temperature range (70-110 °C).
