Rubber Compounding - an overview | ScienceDirect Topics
The fluoroelastomer described is a VDF/HFP dipolymer precompound, Viton ® E-60C, containing about 2 phr Bisphenol AF and 0.55 phr BTPPC accelerator. The medium-viscosity polymer was designed with a considerable high molecular weight fraction to impart enough cohesive strength for good mill mixing.
Base resistant FKM-TPV elastomers - Freudenberg-NOK General Partnership
The rubber is cured in a mold for 7 minutes at 177° C., and post-cured 16 hours at 232° C. Examples 1, 3, and 5-8 are made by dynamic vulcanization of a fluorocarbon elastomer (ETP 600S or P 757) with a radical curing system (Luperox 101XIA5, triallylisocyanurate, and ZnO) in the presence of a thermoplastic (Hylar MP 10, Halar LC50, or Kynar Flex 2500-20), and further in the presence of

Bisphenol AF Bisphenol AF & Derivatives Our Products
Bisphenol AF (CAS# 1478-61-1) is commonly used as a curing agent in the processing of fluorocarbon elastomers (FKM), often in combination with triphenyl benzylphosphonium chloride (BTPPC). Bisphenol AF-cured fluoroelastomers show superior material characteristics, including thermal stability, chemical resistance and compression set resistance

FKM Fluoroelastomers Eagle Elastomer Inc.TypesCrosslinking MechanismsFFKMOn the basis of their chemical composition FKMs can be divided into the following types: 1. Type 1 FKMs are composed of vinylidene fluoride (VDF) and hexafluoropropylene (HFP). Copolymers are the standard type of FKMs showing a good overall performance. Their fluorine content typically ranges around 66 weight percent. 2. Type 2 FKMs are composed of VDF, HFP, and tetrafluoroethylene (TFE). Terpolymers have a higher fluorine content compared to copolymers (typically between 68 and 69 weight per...

FKM Fluoroelastomer SensorsONE
FKM Fluoroelastomer. Fluoroelastomer is a fluorinated carbon based rubber material which is mostly used on pressure measurement equipment to seal joints between components which are either pressurised or water-tight. FKM seals are used inside pressure sensors to seal between the pressure sensing element and the process connection assembly, they are fitted around the outside of male
What is FKM Rubber,Fluoroelastomer Rubber,FKM Viton
What is FKM? Fluroelastomer or FKM is a class of synthetic rubber designed for very high temperature operation. FKM provides extraordinary levels of resistance to chemicals, heat and oil, while providing useful service life above 200°C. FKM are not a single entity but a family of fluoropolymer rubbers. Fluoroelastomers or FKM (sometimes also
