Halogen Free Flame Retardant PP+EPDM Granules（1.6 mm V2）

Introduction
As the base resin, PP is uniformly mixed with halogen-free fire retardant, glass fiber, EPDM and processing modifier in a high speed. After twin-screw kneading granulation, halogen free flame retardant compound (PP+EPDM granules) is formed. Its flame retardant grade is UL94 V-2 (1.6 mm). This flame retardant plastic granule possesses excellent mechanical strength, excellent resistance to stress cracking, heat resistance and good workability. It is extensively applied in home appliances, electronic appliances and other fields. Our company is a professional supplier of flame retardant EPDM halogen free flame retardant compounds in China. Our halogen free flame retardant plastic granules can also be used on cable sheath for subway, mine, ship and warship applications.

Applications
Halogen free flame retardant PP+EPDM granules are widely used for switching components, thermostats, relay housings, circuit breakers, low voltage electrical appliances shell, TV or monitors, business computers, etc. EPDM halogen free flame retardant compound is also used for electroplating processing.

Features
1. This flame retardant plastic granule (PP+EPDM granules) features low water absorption and good overall performance.
2. Our halogen free flame retardant compounds (1.6 mm V2) have excellent machining property and good flame retardant property.
3. Electrical accessories meet all stringent requirements.
4. INFO flame retardant plastic granules can be used under high humidity environments.
5. Non-halogen halogen free flame retardant compounds have excellent heat resistance.

Process
Halogen free flame retardant plastic granules 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 bags with plastic bag lining to package this halogen free flame retardant compound.
