Characteristics of PP: 1. Odorless, odorless, and non-toxic. It is the lightest type of commonly used resin;
Polyamide 2. Excellent mechanical properties, including tensile strength, compressive strength, and hardness, outstanding rigidity and bending fatigue resistance. The movable hinge made of PP can withstand more than 7 × 107 folding and bending cycles without damage, and has poor impact strength at low temperatures. The tensile strength of PP is generally 21-39 megapascals; The bending strength is 42-56 megapascals, the compression strength is 39-56 megapascals, the elongation at break is 200%~400%, the notch impact strength is 2.2-5 kJ/m2, and the low-temperature notch impact strength is 1-2 kJ/m2. Rockwell hardness R95~105;
Polypropylene 3. Good heat resistance, continuous use temperature can reach 110-120 ℃;
4. Good chemical stability, except for strong oxidants, it does not interact with most chemical drugs; At room temperature, solvents cannot dissolve PP, only some halogenated compounds, aromatic hydrocarbons, and high boiling point fatty hydrocarbons can make it swell, and its water resistance is particularly good;
Polyformaldehyde 5. Excellent electrical performance, good resistance to high-frequency electrical insulation, and good electrical insulation in humid environments;
