具有優異的高耐熱性、高剛性、尺寸穩定性、耐化學試劑等特性的材料， 利用這些特征，酚醛樹脂活塞在1974年以來有40年以上的實績。并貢獻1/2以上的輕量化。
 另外(wai)，電瓶車(che)的卡鉗活塞樹脂(zhi)化，我們也在(zai)進行當中。

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.
