Product Description

Duzishan 5420 Polypropylene has good heat resistance, and the product can be disinfected and sterilized at temperatures above 100. Under no external force, it does not deform even at 150. The embrittlement temperature is -35, and embrittlement occurs below -35, resulting in poor cold resistance. The reported values for the glass transition temperature of polypropylene include 18qC, 0qC, 5, etc. This is also due to the different proportions of crystalline and amorphous phases used in different samples, resulting in different chain lengths in the amorphous portion of the molecular chain. The melting temperature of polypropylene is about 40-50 higher than that of polyethylene, which is about 164-170, and the melting point of 100 isotactic polypropylene is 176.
chemical stability
Polypropylene has good chemical stability. In addition to being corroded by concentrated flow acid and concentrated acid, it is also relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, and chlorinated hydrocarbons can soften and swell polypropylene. At the same time, its chemical stability also improves with the increase of crystallinity. Therefore, polypropylene is suitable for making various chemical pipelines and fittings, with good anti-corrosion effects.
Electrical performance
It has a high dielectric coefficient and can be used to make heated electrical insulation products as the temperature increases. Its breakdown voltage is also very high, making it suitable for use as electrical accessories, etc. Good voltage resistance and arc resistance, but high static electricity and easy aging when in contact with copper.
The use of polypropylene:
Thin film products: Polypropylene thin film products are transparent and glossy, with low permeability to water vapor and air, and are respectively blow molded films Polypropylene Abs Plastic Polyformaldehyde 3 Jpg
