Description
As the base resin, PP is uniformly mixed with antioxidant, flame retardant and processing modifier in a high speed. After twin-screw kneading granulation, halogen free flame retardant polypropylene granules come into being. Its flammability level is UL94 V-0 (1.6 mm). It possesses excellent mechanical strength, excellent resistance to stress cracking, heat resistance, cold resistance, wear resistance, good workability and other properties. This flame retardant plastic granule can be used in home appliances, electronic appliances, instruments, auto parts, building materials and other fields.
Advantages
1. Non-halogen flame retardant polypropylene granules own excellent halogen-free and pro-environment properties.
2. This flame retardant plastic granule (1.6 mm V0) enjoys high flammability resistance, high heat resistance and stability and high strength.
3. Halogen free flame retardantPP granules have excellent electrical properties.
Applications
Halogen free flame retardant polypropylene granules (1.6 mm V0) can be extensively used for shell of electrical frame, switch parts, appliance parts, electronic components, connector, electric relay, etc.
