Flame Retardant Fluorosilicone Rubber

 

Flame-retardant fluorosilicone rubber is made of fluorosilicone rubber as the base rubber, adding flame-retardant fillers, cross-linking agents, etc., compounded and vulcanized.

Compared with general flame-retardant rubber, the advantages of flame-retardant fluorosilicone rubber are low hardness, high and low temperature resistance (-60 to 230°C), aging resistance, oil resistance, acid and alkali resistance, good processing and manufacturing performance, and good resistance to heat. Flammability, meet UL94/FV 0 flame retardant level.

Flame retardant fluorosilicone rubber is suitable for high temperature molding and extrusion molding production processes, and users need to select corresponding vulcanizers and vulcanization processes based on actual production.

 

 

Flame-retardant fluorosilicone rubber is mainly used for the sealing of electrical and electronic components such as power supplies, photovoltaic modules, and communication equipment, as well as the sealing and fixing of electronic components. Sealing of other metals, plastics, glass, etc. that have flame retardant requirements

 

 

1. It has excellent flame retardant performance. The cured colloid has high insulation and high voltage resistance, and the flame retardant grade reaches UL94-VO level, which provides a high guaranteed flame retardant coefficient for electronic products and plays a role in the stability of the product during use. Guarantee function, improve the performance and life of the product;

2. It has superior electrical properties, anti-aging, anti-cold and heat alternating performance, moisture-proof and non-swelling, electrical insulation performance, shockproof, waterproof, shock absorption and stability, which increases the safety factor of electronic products during use;

3. It has excellent high bonding strength, especially for electronic components, aluminum, PVC, PBT and other plastics. Excellent adhesion, and at the same time have excellent sealing performance, but also have excellent bonding and flame retardancy.

4. It is non-toxic, non-irritating gas release, solvent-free, non-corrosive, non-polluting, safer and more environmentally friendly. double protection;

5. Excellent weather resistance and anti-aging performance, colloid is full of elasticity and toughness, has excellent adhesion and adhesion to various metal and non-metal materials, and can work for a long time in water, gas, oil, ozone, strong magnetism, high pressure , ultraviolet radiation and harsh environment of wind and rain;

6. It has excellent resistance to severe cold and high temperature, short-term high temperature resistance of 250 degrees, long-term high temperature resistance of 230 degrees, and low temperature resistance of -60 degrees.

 

 

Flame-retardant fluorosilicone rubber decomposes the same as silicone rubber at high temperature, namely: side chain oxidation, main chain breakage, side chain thermal decomposition and various compound reactions. Since the decomposition products can also cause the main chain to break, the heat resistance is worse than that of silicone rubber, and it has begun to oxidize and age at a temperature of 200°C. However, it can be significantly improved by adding a small amount of heat-resistant heat stabilizers such as iron, titanium, and rare earth oxides, and it has sufficient heat resistance even at a high temperature of 230°C.

 

 

1. Mixing: Remix several times on the open mill, add vulcanizing agent, and then adjust back to 0.5mm-1mm thin pass 8-10 times after the material is finished, and then leave the tablet and park it.

2. Vulcanization: Re-mill the fluorine-silicon compound rubber with the vulcanizing agent, and then cut it into the required shape, and then use it

 

Storage method: store in a dry environment at room temperature, valid for one year.

Packing: Packed in plastic bags, 10 kg per bag, two bags per carton.

Shipping: This product is shipped as a non-hazardous chemical.
