The unique physical properties of polypropylene industrial yarns make it suitable for making wires and cables. What are the specific properties? Let us introduce them to you by Xuzhou Heping.
Polypropylene industrial yarn, as the name suggests, the main material is polypropylene, polypropylene is also known as polypropylene, the English abbreviation PP.
1. The specific gravity of polypropylene is 0.89-0.91, which is one of the smaller specific gravity of commonly used plastics at present. It has excellent mechanical strength and high softening temperature. Good low temperature resistance and aging resistance. Only the optical rotation resistance is slightly worse, but it can be improved by adding a stabilizer through copolymerization.
2. General properties of polypropylene: The appearance of PP is very similar to HDPE. It is a white waxy solid. It is transparent, non-toxic, combustible and will continue to burn after leaving the fire.
3. Compared with polyethylene, polypropylene has the following different characteristics:
The surface hardness of PP is higher than that of PE, and the abrasion resistance and bending deformation ability are very good. Therefore, PP is known as "low density high strength plastic".
Another advantage of PP over PE is that there is almost no environmental stress cracking. PP has very good resistance to environmental stress cracking, but due to the high degree of regularity of the molecular structure of PP itself, its impact performance at room temperature and low temperature is very poor.
Electrical insulation properties of PP: PP is a non-polar material, so it has good electrical insulation properties. Its electrical insulation is basically similar to LDPE, and it does not change over a wide frequency range. Due to its extremely low density, the dielectric constant is smaller than LDPE (ε = 2.0 ~ 2.5), the dielectric loss tangent is 0.0005 ~ 0.001, the volume resistivity is above 1014Ω.m, and the breakdown field strength is also very high at 30MV / m; In addition, the water absorption is very small, so PP can be used as a high-frequency insulation material.
Polypropylene industrial yarn is mainly used for the insulation material of cables. The insulating layer is a member that is wrapped around the periphery of the wire and serves as an electrical insulation. It is necessary to ensure the normal transmission function of the wire, and also to ensure the safety of foreign objects and people. So choosing the right insulation material is important.
Polypropylene industrial yarn has the characteristics of high strength, anti-aging, acid and alkali resistance, seawater corrosion resistance, abrasion resistance, light weight, low thermal conductivity, non-hygroscopicity, etc. It is very suitable for the production of cable insulation materials.
In the chemical fiber industry, there is a company producing polypropylene industrial yarn of high quality and widely used, and it can also be customized according to individual needs. This is Xuzhou Heping Chemical Fiber Co., Ltd.
