polypropylene

Product phasical and chemical properties:
Polypropylene is pp for short, is a regular structured crystalline polymer, is local color particles, tasteless, odorless, nontoxic, lightweight thermoplastic resin, the relative density of 0.90 to 0.91, is one of the lightest general resin. Good mechanical properties, and good heat resistance. Melting point is about 170 degree celsius. It is indeformable under 150 degree celsius In the absence of external force. Good chemical stability, acid and alkali-resistant and organic solvents resistant, and donÿ®t have reaction with most chemical medicines, and almost non-absorbent water. The deficiency is easy to embrittlement, poor impact strength under low temperature, but can be improved by method of additives, blends or copolymerization etc..

Production Technology:
Applying the Spheripol patented technology form Himon company, the process use Ziegler-Natta catalyst liquid bulk polymerization, to directly get spheroidal polypropylene powder with diameter form 500 ¥Ìm~ 5 mm. It has the following features: high activity catalyst, good selectivity, high product isotacticity, non deliming, non deprivation of random polymer, solvent-free, and can not be pelleting etc..The product range is wide, high quality and wide use.
