Introduction
Adopting PP as the base resin, halogen free flame retardant PP granules are made by twin-screw kneading granulation by evenly mixing PP with antioxidant, flame retardant and processing modifier in a high speed. Its flammability level (flame retardant grade) is UL94 V-0. Fire retardant granules (0.5 mm V0) are well known for excellent mechanical strength, excellent resistance to stress cracking, heat resistance, good workability and other properties. This flame retardant PP granule can be used in home appliances, electronic appliances and other fields.
Features
1. Halogen free fire retardant granules own excellent halogen-free and pro-environment properties.
2. It possesses the advantages of high flammability resistance, high heat resistance and stability and high strength.
3. Halogen free flame retardant PP granules have outstanding flame-retardant properties and excellent electrical properties.
4. Non-halogen fire retardant granules can realize injection or extrusion molding.
Applications
Halogen free flame retardant PP granules (0.5 mm V0) can be used for shell of heater, electrical frame, switch parts, appliance parts, electronic components, connector, electric relay, coil frame, etc. It can also be used as insulation sheet used in home electrical appliances.
