PP Parts

• Polypropylene resin is one of the four general-purpose thermoplastic resins (polyethylene, polyvinyl chloride, polypropylene, and polystyrene), which is produced by polymerization using propylene as raw material and ethylene as comonomer.
• Good heat resistance, continuous use temperature up to 110-120 ℃.
• Excellent mechanical properties, including tensile strength, compressive strength, and hardness, outstanding rigidity and bending fatigue resistance. The movable hinge made of PP can withstand 7 × More than 107 folds and bends without damage, resulting in poor impact strength at low temperatures. The tensile strength of PP is generally 21-39 MPa; Bending strength 42-56 MPa, compressive 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.
