Description
FR-Si9501 is a silsesquioxane FR which has excellent weather resistance, hydrolysis resistance and long lasting fire resistance function. As a halogen-free flame retardant, FR-Si9501 need very low dosage in application while maintaining the original physical properties of the resin, so it is It is widely used in PC, PC alloy, PC + GF electricity meter shell, wall switch panel and charger shell etc.
non-applicable range:
thin-walled (1.0mm below) PC products are not suitable.
Product characteristics:
1. Product does not deliquescence and no hydrolysis.
2. Flame retardant function can be maintained in a long time.
3. Can be used with other flame retardants to achieve better flame resistance performance.
4. FR-SI9501 dosage is low, so can reduce cost of the product
