KR630 (Low Termerature Terpolymers)
FKM (Fluorocarbon Rubber or Fluoroelastomer) Raw material
FLUONOX® KR630 is a fluoroelastomer which consist of HFP, VDF and TFE. FLUONOX® KR630 is Bisphenol AF cure incorporated fluoroelastomer. Fluonox KR630 exhibits the best low temperature properties among standard Fluoroelastomer, with a TR10 of -19°C. It is suitable for injection and transfer moulding. FLUONOX® KR630 grade is an excellent choice for making O-rings, seals and gaskets where better low Temperature properties versus copolymers are required.
* Improved low temperature property vs. standard copolymers
* Good chemical resistance
* Good Compression set resistance
* Good mold release
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.
