具有优异的高耐热性、高刚性、尺寸稳定性、耐化学试剂等特性的材料， 利用这些特征，酚醛树脂活塞在1974年以来有40年以上的实绩。并贡献1/2以上的轻量化。
另外，电瓶车的卡钳活塞树脂化，我们也在进行当中。

Our phenolic molding compounds have excellent heat resistance, high modulus, dimensional stability, and chemical resistance. Taking advantage of these feature, brake piston made of phenolic resin since 1974, it has contributed more than half the weight reduction of iron pistons.
We have also started to expand caliper pistons for electric motorcycles.
