Halogen Free Flame Retardant PP Granules（Glow Wire 850℃）

Description
Adopting PP as the base resin, halogen free flame retardant polypropylene granules are made by twin-screw kneading granulation by uniformly mixing PP with antioxidant, flame retardant and processing modifier in a high speed. The flame retardant level is that the glow wire can keep not igniting for 30 seconds under the temperature of 850℃. Our flame retardant PP granules enjoy the advantages of excellent mechanical strength, excellent resistance to stress cracking, heat resistance and good workability. In some applications, these polypropylene granules (glow wire 850℃) can replace flame retardant PA66 to realize injection molding for electronics and electrical parts.

Features
1. Halogen free flame retardant PP granulespossess excellent halogen-free and pro-environment properties.
2. It owns high flammability resistance, high heat resistance and stability and high strength.
3. Halogen free FR polypropylene granules (glow wire 850℃) have outstanding flame-retardant properties and excellent electrical properties.
4. This halogen free PP meets the UL94 V-0 standard.
5. Halogen free flame retardant PP granules can realize injection or extrusion molding.

Applications
Halogen free flame retardant polypropylene granules (glow wire 850℃) 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 on home electrical appliances.
