PP is the abbreviation of polypropylene plastic, and PP recycled material is also polypropylene recycled material. Regeneration also refers to recycling, which is a general term after the second thermoplastic treatment relative to new raw materials. After the general plastic is used once, it can be used as a raw material again after being thermally extruded and granulated by a recycling machine. The recycled and extruded polypropylene material is called PP recycled material.

PRODUCT MATERIALS
1. PP impact-resistant recycled material: impact-resistant and cold-resistant, good impact resistance, high fluidity, high gloss, good toughness, and impact resistance; among them, the white background of the special-grade material is transparent and has very few black spots, which can be used as a substitute for new materials. ; The PP materials produced are mainly used for: injection molding, extrusion, wire drawing, etc.; applicable products are: electrical enclosures, chemical barrels, daily necessities, sheets, packing belts and plastic modification and other products;
2. PP wire drawing recycled material: there are ordinary injection molding grade, high light impact resistant environmental protection grade, wire drawing grade (over 250 mesh) and extrusion grade hollow board special material; Applicable products: handles, table legs, trash cans, sports equipment, Trays, plastic baskets, electrical enclosures, etc.;
3. PP fiber-reinforced fire-resistant modified material is suitable for various high-grade injection molding products;
Features: Propylene is a non-toxic, odorless, tasteless milky white crystalline polymer with high crystallinity and regular structure, so it has excellent mechanical properties. Its yield, stretch, compressive strength, hardness and elasticity are higher than HDPE. Its melting point is 164~170 degrees, and the products can be sterilized at temperatures above 100 degrees. The chemical stability of polypropylene is very good. In addition to being corroded by concentrated nitric acid, it is relatively stable to other chemical reagents. Processing methods: injection molding, extrusion molding, hollow molding, rotational molding; Uses: It can be used as automobile, electrical, mechanical, instrument, daily necessities and building materials and general pipes, profiles, plates and various small containers
