Halogen Free Flame Retardant PP+EPDM Granules（1.6 mm V0）

Description
Choosing PP as the base resin and uniformly mixing it with halogen-free fire retardant, EPDM (Ethylene-Propylene-Diene Monomer) and processing modifier in a high speed, halogen free flame retardant EPDM compound granules are formed after twin-screw kneading granulation. Its flammability level is UL94 V-0 (1.6 mm). This halogen free flame retardant compound possesses excellent mechanical strength, excellent resistance to stress cracking, heat resistance and good workability. It is widely used for electroplating processing and applied in home appliances, electronic appliances and other fields. Our company is a professional supplier of flame retardant EPDM compound granules (PP+EPDM) in China. Our halogen free flame retardant compounds can also be used on cable sheath for subway, mine, ship and warship applications.

Applications
The halogen free flame retardant EPDM compound granules are 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 halogen free flame retardant compound (PP+EPDM granule) features low water absorption and good overall performance.
2. INFO non-halogen flame retardant EPDM compound granules can be used under high humidity environments.
3. Electrical accessories meet all stringent requirements.
4. Our halogen free flame retardant compounds (1.6 mm V0) have excellent machining property and good flame retardant property.
5. Non-halogen flame retardant EPDM compound granules have excellent heat resistance.

Process
This halogen free flame retardant compound (PP+ EPDM granule) 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 flame retardant EPDM compound granules.
