FKM pre-compound is a functional masterbatch produced by pre-mixing fluorocarbon elastomer (FKM) gum with bisphenol AF (vulcanizing agent) and BPP accelerator. It contains no acid acceptor, reinforcing filler or processing aid, and is a "semi-finished" pre-dispersed intermediate.
Key Advantages
Excellent dispersion – Pre-disperses the small amounts of curing agent and accelerator into the rubber matrix, solving the problems of dusting and poor dispersion common with powder additives during mixing.
Simplified batching – In plant compounding, simply add this pre-compound together with additional gum, acid acceptors (MgO, Ca(OH)₂), carbon black, etc. into the internal mixer to quickly prepare a full compound.
Consistent batches – The precise ratio of curing agent/accelerator in the pre-compound ensures consistent cure characteristics for each batch of the final compound.
Scorch safety – The pre-dispersed masterbatch design helps improve processing safety.
Convenient storage – Stable for long-term storage; ready to use with the complementary components after opening.
Typical Applications
As an intermediate for FKM compounds, used to produce various products such as automotive oil seals, O-rings, fuel system seals, chemical gaskets, etc.
