How to choose fluoroelatomer?
FKM Copolymer vs FKM Terpolymer
Copolymer: 66% fluorine content, general application, resistance to oil, fuel, heat, chemicals. Common application is o rings, oil seals, packers, gaskets, etc.
Terpolymer: higher fluorine content than copolymer 68% fluorine content. Better resistance to oil, fuel, heat, chemicals, used in harsh environment which copolymer can’t satisfy the requirements.
Bisphenol curable FPM vs Peroxide curable FPM
Bisphenol curable FPM has low compression set, offer used for o-rings, shaft seals, piston seals. Price is good.
Peroxide curable FPM has better resistance to polar solvents, steam, acids, chemicals. Price is much higher. Its often used for wearable devices, extrusion fuel hoses.
Storage
Viton precompound should be stored in a cool, dry and ventilated place. Shelf life is 24 months since production date.
Package
1. To prevent the compounds stick to each other, we apply PE film between each layer of FKM compounds.
2. Every 5kgs in a transparent PE bag.
3. Every 20kgs/ 25kgs in a carton.
4. 500kgs on a pallet, with strips to reinforce.
