DuPont white polypropylene PP rod

 [PP] Rod Products: color: white, gray size: 10-500mm * 1000 / 2000mm: English name Polypropylene, a polymer, monomer propylene CH2 = CH-CH3, obtained by addition polymerization of polypropylene chemical formula can be expressed as (C3H6) n, simple structure can be expressed as [-CH2-CH (CH3) -]. n PP PP Rod Rod is a semi-crystalline materials. It is harder than PE and has a higher melting point. Since the type of PP homopolymer is higher than the temperature above 0 ℃ very brittle, so many commercial PP material is added 1 to 4% ethylene random copolymer or a copolymer of a higher ratio of clamp-stage ethylene content. Copolymer PP material has a lower heat distortion temperature (100 ℃), low transparency, low gloss, low rigidity, but have a stronger impact strength. PP intensity with increasing ethylene content increases. PP Vicat softening temperature of 150 ℃. Due to the high degree of crystallinity, surface stiffness and scratch resistance properties of this material very well. PP environmental stress cracking problem does not exist. Features: Low density, heat, deformation, high stiffness, high surface hardness, good chemical stability, excellent electrical performance, non-toxic, uniform color, smooth surface, easy installation and maintenance, long life, easy processing welding firm characteristics. [1] Application: Equipment drinking water pipes, seals, spray carrier, corrosion-resistant tanks, barrels, acid industry, waste water, emissions equipment, scrubbers, clean rooms, semiconductor manufacturing and related industries of mechanical , food machinery and chop plate, plating processes. Status: Currently PP rods are mainly two kinds of domestic and imported, domestic PP stick to occupy most of the market. Domestic PP stick cheap, but the prevalence of deformation, oval, bubbles and other issues. Imported PP excellent stick performance, color uniformity, good processing performance, but the price is slightly expensive. The main brands of imported PP stick Germany Gaelic (GEHR), DuPont factory.
