Description:
Polypropylene(PP) , a kind of non-toxic,odorless, tasteless opalescent polymer with high crystallization, the melting point among 164- 170C, the density among 0.90-0.91g/cm3 , the molecular weight is about 80,000- 150,000. PP is one of the lightest plastic of all varieties at present, particularly stable in water, with a water absorption rate in water for 24 hours is only 0.01%.
Application:
Polypropylene L5E89 adopts the Unipol gas-phase fluidized bed process of US Grace, it is widely be used to produce woven bags, fiber,
applicable for textile,jumbo bags,carpet and backing etc.
Packaging:
In 25kg bag, 16MT in one 20fcl without pallet or 26-28MT in one 40HQ without pallet or 700kg jumbo bag, 26-28MT in one 40HQ without pallet.
