PP polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90~0.91g/cm3, which is currently one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water for 24 hours is only 0.01%, and the molecular weight is between 80,000 and 150,000. The moldability is good, but because of the large shrinkage, thick-walled products are easy to dent. The surface of the product has good gloss and is easy to color.
PP filling modification, adding a certain amount of inorganic minerals to PP, such as talc, calcium carbonate, titanium dioxide, mica, etc., can increase rigidity, improve heat resistance and gloss; add carbon fiber, boron fiber, glass fiber, etc. Improve tensile strength; adding flame retardant can improve flame retardant performance; adding antistatic agent, coloring agent, dispersant, etc. can respectively improve antistatic property, coloring and fluidity, etc.; adding nucleating agent can speed up The crystallization speed increases the crystallization temperature to form more and smaller spherical crystals, thereby improving transparency and impact strength.
