According to the chemical composition of PP is the molecular chain of the regular arrangement of the crystal shape and other regulatory polymers. It is also divided into equal-gauge PP (PP) and Random pp, as the name suggests, such as PP is a kind of polypropylene crystallinity of up to 95%, molecular weight between 8.15 million of the thermoplastic resin, and the random pp is polypropylene at room temperature is a non crystalline, micro-viscous white wax, low molecular weight. Commonly known as space glass. Non-toxic tasteless, strength, stiffness, heat resistance are relatively good, can be used around 130 degrees, there is a better electrical performance, moisture absorption small, good fluidity, corrosion-resistant, can be used for utensils.
