KR435 (Bisphenol /Diamine Cureable Terpolymers Raw Gums)
FKM (Fluorocarbon Rubber or Fluoroelastomer) Raw material
Fluonox®KR435 is a medium – low viscosity terpolymer with 68.5% Fluorine content, consisting of HFP, VDF and TFE.Fluonox®KR435 doesn’t content curatives, it can be cured with diamine or bisphenol AF curing systems. Fluonox®KR435 shows the typical chemical resistance of FKM terpolymers, thus it is used where better chemical resistance compared to standard FKM copolymer is required. It is suitable for compression, transfer and injection moulding of O-rings, shaft seals, valve stem seals, gaskets where good chemical resistance is required. It can also be compounded and dissolved in polar media for Coating applications.
* Excellent Chemical resistance including oxygenated fuels
* Outstanding heat resistance
* Easy soluble in polar solvents
Safety and Handling
Handling and processing of fluoroelastomer must be done in ventilated areas to prevent personnel exposure to the fumes liberated during curing or use of cured rubber at high temperature. During the process, some fumes may generate at high temperature which are harmful for human beings. Fumes should not be inhaled; eye and skin contact must be avoided. In case of skin contact flush skin with cold water immediately. In case of eye contact, flush with water immediately and seek medical help. Smoking tobacco or cigarettes should not be allowed in working area. Mixing agents that contain metallic particulate such as powdered aluminium can rapidly decompose at high temperature; therefore do not use metallic particulate as mixing agent. Fluoroelastomer should be stored away from heat. It should be kept in clean and dry area where it can be protected until it is used. Please read the Material Safety Data Sheet before handling the product.
