All Non-toxic And Odorless Isotactic Polypropylene Granules

Isotactic polypropylene is a highly crystalline (95% crystallinity) thermoplastic resin with regular configuration. The product is natural color pellets, non-toxic, tasteless, odorless and light weight polymer with a density of 0.90-0.91g/cm3, which is the lightest among general-purpose plastics. Rigidity, good wear resistance, high hardness, good high temperature impact (but it will drop sharply below -5A C). Strong resistance to repeated folding. Good heat resistance, heat distortion temperature 114A C, Vicat softening point > 140A C, melting point 164-167A C, continuous use temperature up to 110-120A C, under no-load conditions, use temperature up to 150A C, is The only general-purpose plastic product that can be boiled in water and sterilized at 130A C. It has good chemical stability and does not interact with most chemicals except for strong oxidizing media. The stability to water is particularly prominent, not only insoluble in water, but also hardly absorbs water, and the water absorption rate in water for 24 hours is only 0.01%. Excellent electrical insulation performance, good voltage resistance and arc resistance. Its main disadvantages are poor light resistance, easy aging; poor cold resistance, poor low temperature impact strength, poor toughness, high static electricity, poor dyeability, printability and adhesion, but it can be improved by adding additives and co-mixing and co-polymerization .
