Halogen Free Flame Retardant PP Sheets（0.5 mm V2）

Introduction
Adopting PP as the base resin, it is uniformly mixed with antioxidant, flame retardant and processing modifier in a high speed. After twin-screw kneading granulation, halogen free flame retardant polypropylene sheet is extruded by the calendaring machine. Its flame retardant grade is UL94 V-2 (0.5 mm). This flame retardant film is famous for its excellent mechanical strength, excellent resistance to stress cracking, heat resistance, cold resistance, wear resistance and good workability. It is widely applied in home appliances (television), electronic appliances and other fields. Our halogen free flame retardant polypropylene sheets can also be used on cable sheath for subway, mine, ship and warship applications. Our company is a specialized manufacturer of flame retardant film materials in China.

Applications
Halogen free flame retardant polypropylene sheet is extensively used for insulation sheets, power supplies, switching components, thermostats, relay housings, circuit breakers, low voltage electrical appliances shell, TV or monitors, business computers, etc.  

Features
1. This flame retardant film features low water absorption and good overall performance.
2. INFO halogen free flame retardant polypropylene sheets can be used under high humidity environments.
3. Electrical accessories meet all stringent requirements.
4. Our flame retardant films possess excellent machining property and good flame retardant property.
5. Halogen free flame retardant polypropylene sheet owns high flammability resistance and high heat resistance and stability.

Process
PP non-halogen flame retardant sheets (0.5 mm V2) can be extruded and molded by a general screw extruder. The extruding velocity and temperature can be adjusted appropriately according to specific requirements.

Packaging Specification
We use kraft bag with a plastic bag lining to package this type of flame retardant film.
