PE/LDPE/MDPE/HDPE/LLDPE Granules for plastic raw material
Product Description
Polyethylene, for short PE, is a kind of thermoplasticity resin, which is aggregated by ethylene. According to PE density, it can be divide into four mainly kinds: HDPE (Low Density Polyethylene), LDPE (Low Density Polyethylene), LLDPE (Linear Low Density Polyethylene), MDPE(Medium Density Polyethylene).
