    Introduction to Polypropylene

    Polypropylene is a polymer formed by the addition polymerization of propylene. It is white waxy material, transparent and light in appearance. The chemical formula is (C3H6) N, the density is 0.89 ~ 0.91g/cm3, [1] inflammable, melting point is 189℃, softening at about 155℃, and the operating temperature range is -30 ~ 140℃ [2]. Under 80℃ can resist the corrosion of acid, alkali, salt solution and a variety of organic solvents, can be decomposed under high temperature and oxidation. Polypropylene is widely used in the production of fiber products such as clothing and blankets, medical instruments, automobiles, bicycles, spare parts, transportation pipes and chemical containers, as well as in the packaging of food and medicine.

    Characteristics of PP plastic material

    1, colorless, tasteless, non-toxic. 2, the appearance is white waxy, but transparent than PE. 3, low density: 0.9-0.91 grams/cubic meter, is one of the lightest plastics. 4, has a particularly high bending fatigue strength - 100 fold glue. 5, good heat resistance (120℃). 6. Good boiling water and steam resistance (high pressure disinfection products). 7. It is easy to age under the action of heat, oxygen and light.

    PP plastic properties

    1, physical properties: non-toxic, odorless, tasteless, milky white high crystalline density is only 0.9-0.91g/cm3, good stability to water. 2,thermal performance: has good heat resistance, its products can be disinfected and sterilized at the temperature above 100℃, in the condition of no external force, 150℃ is not deformed. Embrittlement temperature is -35℃, below -35℃ will occur embrittlement, cold resistance is not as good as polyethylene.

    3, chemical stability: Chemical stability is good, besides can be concentrated sulfuric acid, nitric acid erosion, for other kinds of chemical reagents are stable, but the low molecular weight fatty hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon can make polypropylene softening and swelling, such as its chemical stability at the same time there is some increase with the increase of the crystallinity, chemical pipe and fittings for the production, so the polypropylene anti-corrosion effect is good. 4, electrical properties: a high dielectric coefficient, and with the rise of temperature, can be used to make heated electrical insulation products. Its breakdown voltage is also very high, suitable for electrical accessories, etc. Voltage resistance, arc resistance is good, but the electrostatic degree is high, and copper contact is easy to aging.
