The organosilsesquioxane resin flame retardant is a new flame-retardant element, which is the future trend of flame retardant research. With its excellent flame retardancy (low burning rate, low heat release, anti-dripping), molding processability, Environmental friendliness and unique style, with broad prospects for development.
❖ FR-SI series has a unique ultra-high heat resistance, resistance to long-lasting fire resistance, and rapid char formation into slag, easy dispersion, resistance to hydrolysis and other characteristics.
The important fire-retardant elements in the fire prevention of PC thin-wall products
In the non-halogen-free flame retardant system, the amount of halogen-containing flame retardant can be greatly reduced, thereby improving the overall performance of the product.
Long-lasting flame retardancy Heat resistance Hydrolysis resistance Weatherability Fluidity
FR-SI Series Application Feature Description
✦ 1. Ultra-high heat resistance, long-lasting fire prevention, char formation
✦2. Trace addition, excellent performance. Little impact on physical properties, while maintaining a certain degree of light transmittance
✦ 3. Free of Chlorine, Bromine and Phosphorus, Absolutely Environmentally Friendly Halogen Free Flame Retardant
✦4. Some silicon-based flame retardants can achieve thin wall flame retardant
✦ 5. Can be used in conjunction with different types of flame retardants to achieve better flame retardancy.
The use of lanthanum and bromine products can reduce the amount of bromine flame retardant added.
Thorium and phosphorus products can be used together to achieve alloy flame retardancy and reduce phosphorus flame retardant dosage
