Customizing Recycled PP Granules to Meet Specific Requirements

recycled pp granule is a kind of thermoplastic synthetic resin with excellent properties. It is a colorless translucent thermoplastic lightweight plastic with chemical resistance, heat resistance, electrical insulation, high mechanical strength and good high wear-resisting processing capability. It is widely used in the production of clothing, blankets and other fiber products, medical instruments, automobiles, bicycles, spare parts, transportation pipes, chemical containers and so on, as well as food and medicine packaging.

recycled pp granule has excellent mechanical properties, including tensile strength, compression strength and hardness, outstanding rigidity and bending fatigue resistance. Movable hinges made of recycled pp granule can withstand more than 7×107 folding and bending without damage, and the impact strength is poor at low temperature. The tensile strength of PP is generally 21-39 mpa; Bending strength 42-56 mpa, compression strength 39-56 mpa, elongation at break 200% ~ 400%, notch impact strength 2.2-5 kJ/m2, low temperature notch impact strength 1-2 kJ/m2. Rockwell hardness R95~105.

recycled pp granule is a polymer developed from propylene additive reaction. White waxy material, transparent and light in appearance. The chemical formula is (C3H6)n, the density is 0.89 ~ 0.91g/cm3, flammable, melting point 189℃, at 155℃ or so softening, the use temperature range is -30 ~ 140℃. Under 80℃ can resist the corrosion of acid, alkali, salt solution and a variety of organic solvents, can decompose under high temperature and oxidation.

recycled pp granule has good mechanical properties, which can be directly manufactured or modified to manufacture parts of various mechanical equipment, such as industrial pipes, agricultural water pipes, motor fans, and capital construction templates. The modified polypropylene can be molded into bumpers, scratches, etc., greatly reducing the body weight to achieve the purpose of energy saving. recycled pp granule can also be applied to the preparation of various corrosion-resistant conveying pipes, storage tanks, valves, special-shaped fillers in packing towers, filter cloth, corrosion-resistant pumps and the lining of corrosion-resistant containers. In medicine, it can be used to make medical devices; recycled pp granule could also be developed and applied in energy industry through grafting, compounding and blending processes.
