1£® CHARACTERISTIC AND
USAGE
This
product is a two stage phenolic, glass filled, special purpose moulding
material. it is suitable for close tolerance applications such as transmission
valve bodies, and disk brake pistons where good dimensional stability
and compatibility with transmission and brake fluid is essential. This
product appearance submits granular. According to client needs, can offer
color series product.
