PP material, the full name of polypropylene, PP tensile strength and rigidity are relatively good, but the impact strength is poor, especially at low temperatures, and poor impact resistance. In addition, if the products are molded with orientation or stress, the impact strength will also be significantly reduced. Although the impact strength is poor, after filling or reinforcing and other modifications, its mechanical properties in many areas can compete with the higher cost of engineering plastics, which is an excellent performance of plastic materials. Its main properties include:
1. Physical properties.PP is a non-toxic, odorless, tasteless, milky white, highly crystalline polymer with relatively low density, typical values of 0.90~0.91g/cm³, which makes it one of the lowest density varieties of all plastics.
2. chemical stability. PP has good acid and alkali resistance and oil resistance, can be in high temperature, high pressure, and harsh environments to maintain stability, and is not easy to chemical corrosion. This makes Chemical-Resistant Polypropylene Hex Nuts suitable for making corrosion-resistant containers, pipelines, and other fastening connections.
3. thermal stability. PP has a high melting point, usually 160 ~ 170 ℃, and good heat resistance, so it can maintain stable performance at high temperatures. Its heat distortion temperature is usually 80~100℃, which makes it suitable for high-temperature environments.
4. Mechanical properties. PP's tensile strength and stiffness are large, especially at high temperatures, and they decrease less with increasing temperature. In addition, PP has good flexural fatigue life and impact resistance.
5. processability. PP is easy to process molding, blow molding, extrusion, injection molding, and other processes that can be used to manufacture a variety of shapes of products.
6. surface properties. PP products have good surface gloss, easy to color.
Disadvantages. PP has lower dimensional accuracy, insufficient rigidity, poor weather resistance, and the existence of post-shrinkage phenomenon, after demolding, may be aging, brittle, and easy to deform. Due to these characteristics of PP material, Chemical-Resistant Polypropylene Hex Nuts are also widely used in food packaging, agricultural machinery and equipment, industrial machinery and equipment, automobile manufacturing, and daily life, such as the production of manufacturing furniture, automobile bumpers, and so on.
