PP particle manufacturers say PP particles refers to polypropylene, is a colorless, tasteless, non-toxic, translucent solid material. Polypropylene is a synthetic thermoplastic material with excellent technical properties as well as a resin, is a colorless translucent thermoplastic lightweight general purpose plastic.

Polypropylene (PP), as one of the main plastics, has good electrical properties and high-frequency insulation properties. It is not affected by humidity, but becomes brittle at low temperatures, is not wear-resistant, and is easy to age. Suitable for making general mechanical parts and corrosion-resistant parts and insulation components.

PP granule manufacturers introduce the characteristics of PP plastic:

1. The density of PP material is relatively small (0.91 g/cm ^ 3), which is actually a small density in common plastics.

2. PP material has good stress cracking resistance and high bending fatigue life.

3, good heat resistance. PP products can be used for a long time in a high temperature environment below 100 degrees. The temperature can reach about 150 degrees without obvious deformation.

4. Good chemical stability. Polypropylene has good chemical stability and is inert to most acids, bases, salts and oxidants. In addition, PP has a wide range of application technologies for the use of food grades.

5. Machinability. Once the PP particles reach a certain temperature, they melt rapidly and are completely transformed into a molten state within a few degrees. The melt viscosity of PP is relatively low, so it has a good fluidity in the processing of molding technology, especially when the melt flow data rate is high, the melt viscosity has little effect, and it is suitable for the injection molding of large thin-walled products in China.

What is the difference between PP plastic and ABS engineering plastic?

  PP granule manufacturersThe plastic antibody has excellent impact strength and can be used at lower temperatures. With China's excellent wear resistance, good dimensional stability and oil resistance; at -40 ℃ can still show our certain toughness, can be used in the temperature control range of -40~100 ℃.

Good electrical insulation, almost independent of temperature, humidity and frequency.

PP particle manufacturers: not affected by water, inorganic salts, alkali and various acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons, acetic acid and vegetable oil erosion will cause different stress cracking. ABS has poor weather resistance and is easy to degrade under the action of ultraviolet rays. PP plastic has high crystallinity and regular structure. The mechanical property value of polypropylene is higher than that of polyethylene, but it belongs to low variety.

The tensile strength can only reach 30 MPa or slightly higher.

PP granule manufacturer: temperature and loading rate have a great influence on the toughness of polypropylene. Polypropylene has good heat resistance, the product can be sterilized at a temperature above 100 ℃, and will not be deformed without external force at 150 ℃.

  PP granule manufacturers: Good anti-corrosion effect. It has a high dielectric coefficient and can be used to manufacture electrical insulation products that are heated with increasing temperature. It also has a high breakdown voltage and is suitable for use as electrical accessories. It has good voltage resistance and arc resistance, but has high static electricity, and it is easy to age in contact with copper.
