Transparent products for a variety of production, injection stretch blow, injection molding. Have good transparency, high gloss, color glossy white and clean, chipping, high temperature, rigidity, good moisture resistance, excellent performance odorless and so on. Physical properties: Polypropylene is non-toxic, odorless, tasteless milky color high formation of polymer crystals-density is only 0.90 ~ 0.91g / cm3, is by far the lightest of all molecules variety of plastics First, it firmly stable water in particular, water absorption in water 24h of only 0.01%, molecular weight between about 8 to 150,000, good formability, but shrinkage large, thick-walled products easy to sink into, product appearance good gloss, easy coloring. Performance: Polypropylene PP Secco K4912, this product is a colorless cylindrical particles. Mechanical Properties: high crystalline polypropylene is formed, the structure return home, and therefore have good mechanical properties, their strength and hardness, flexibility are (polypropylene) than HDPE, high return home because the molecular structure itself, but in the room Under mild low temperature, increase in molecular weight of time, so the poor impact strength, the PP is coming to the fore in the performance of anti-buckling fatigue resistance, impact strength also increases, but the molding processability is deteriorated, such as with a living hinge integrally injection molded PP, sustain 7X107 Fold the opening and closing times without missing buckling bad remnants, dry friction coefficient and nylon similar, but in an oil lubricant, not as nylon.
