Black 90 Shore A High Tensile Strength FKM Uncured Rubber Compound Fluoroelastomer
1. O-ring, gasket, pure rubber products with fluororubber mixed rubber
Description:
The rubber compound is made of high-grade raw rubber and various top-grade auxiliary materials, and is mixed according to a strict process. It is mainly used for injection and moulding products.
It has good fluidity, easy to tear and less burrs, easy to mold, and mold pollution small. Specifically, the formula can be designed according to the product performance requirements provided by the customer;
Molded O-rings, gaskets, rubber sheets, rubber strips, and various non-framed rubber accessories;
Characteristics:
The main chemical components are copolymers of vinylidene fluoride, tetrafluoroethylene, hexafluoropropylene, etc.
The fluorine content of the binary copolymer is 66.0%, and the fluorine content of the terpolymer is 68.0%.
The rubber material has no peculiar smell and is mainly used for sealing products;
3. No. vulcanization, excellent mechanical properties, suitable for large-scale products, but with a small amount of peculiar smell.
2. A fluororubber compound is used to bond the oil seal with the skeleton
Description:

Safety tips for product processing
1. Fluorine rubber will decompose in a small amount in an environment of 260~300 ℃ for a long time.
Its main components are toxic hydrogen fluoride and fluorocarbon.
When it is higher than 300 ℃, the product decomposes faster, and when exposed to an open flame, it will also release Toxic hydrogen fluoride and fluorocarbons; so the vulcanization temperature cannot exceed 220 degrees Celsius.
2 . Processing considerations
The rubber compound should be kept clean during the process of mixing and semi-finished products,and no other impurities should be mixed in;
3. Precautions for storage
Fluorine rubber is more sensitive to water and light and should be stored in a clean, cool and dry place; The storage temperature of the rubber compound should be controlled within 25 degrees.
4. Quality issues
If the rubber material is found to have appearance quality problems during use, the rubber material should be isolated and cannot be used immediately, and timely feedback to us, we will provide solutions as soon as possible, and we will not be responsible for the product quality caused by our own use;
When you find quality problems in production, you should promptly feedback to us, while keeping samples, we will provide solutions as soon as possible.
The products are packed in polythene plastic bags and packed in cartons of 25kg net each.
