Polypropylene (PP) What is PP plastic? It is one of the lightest plastics. Its yield, tensile and compressive strength and hardness are superior to those of low-pressure polyethylene. It has outstanding rigidity, good stress relaxation resistance and heat resistance at high temperatures (90 ℃). It is used as a general structural part and a piece of corrosion-resistant chemical equipment, and a heated electrical insulation part. Polypropylene-PP
High pressure low density polyethylene (LDPE) LDPE material is the lightest type of polyethylene resin.

It has flexibility, extensibility, electrical insulation, transparency, easy processing, and certain air permeability.

It is mainly used as film products, injection molded products, medical appliances, pharmaceutical and food packaging materials, blow molded hollow molded products, etc.   
Polyethylene terephthalate-1,4-cyclohexanedimethoxide (PETG) What is PETG? It has good viscosity, transparency, color, chemical resistance, and stress whitening resistance.
PETG has excellent processing and molding performance. Designed in any shape according to the designer’s intention.
It can apply to food, medicine, cosmetic packaging, cosmetic injection molding, and other fields. PETG
Polyamide (PA, nylon) Polyamide properties are excellent.
Due to its unique low specific gravity, high tensile strength, wear resistance, good self-lubricating, excellent impact toughness, and rigid and flexible properties, PA can be processed into various products to replace metal.
Typical products include pump impellers, fan blades, valve seats, bushings, bearings, various instrument panels, automotive electrical instruments, cold and hot air regulating valves, and other parts. Polyamide has the largest proportion of consumption in the automotive industry, followed by electronics and electrical. PA-nylon


PC plastic has outstanding impact strength and creep resistance, high heat resistance, good cold resistance, embrittlement temperature reaches – 100 ℃, bending and tensile strength equivalent to nylon, high elongation, and elastic modulus.  It can be used as gears, worm gears, racks, cams, bearings, spindles, pulleys, transmission chains, nuts, washers, pump impellers, lampshades, containers, shells, covers, etc. Polycarbonate-PC
Polymethyl methacrylate (, acrylic, plexiglass) It is the best organic synthetic transparent material.
