■
Fluoroelastomer terpolymer material, ASTM FKM (Viton
®
B with a C Cure or Fluorel FT2350)
per FSA-DSJ-401-94, Para. 3.1 (virgin FKM 68% by weight Flourine / 70% by weight FKM,
balance 30% by weight thermal type carbon black with calcium hydroxide. Magnesium
oxide and less than 5% by weight process aids).
■
Aramid / fiberglass reinforcing material treated to ensure a minimum 24 lbs. / lineal inch
Adhesion per ASTM D-413
■
Heavier FKM ply on gas slide providing optimum “unbalanced ply” design
■
Computer controlled belt press that guarantees optimum uniform pressure and heat
distribution over the entire material surface
