What are the advantages of PP material?
1, polypropylene has good heat resistance, products can be sterilized at temperatures above 100 degrees C, without external force, and no deformation at 150. The embrittlement temperature is -35 C, and the brittleness will occur at lower than -35 C, and the cold resistance is not as good as that of polyethylene. For polypropylene glass transition temperature values reported a 18qC, OqC, 5 DEG C, this is because people with different samples, containing crystalline phase and amorphous phase of different proportion, so that the amorphous part caused by the different chain length of molecular chain. The melting temperature of polypropylene increased by 40 than 50% about approximately 164 polyethylene, 170 C, 100% isotactic polypropylene melting point of 176 DEG C
2, the chemical stability of polypropylene is very good, in addition to being concentrated sulfuric acid and concentrated nitric acid erosion, are relatively stable in a variety of other chemical reagents; but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make polypropylene softening and swelling, while its chemical stability with the increase of the crystallinity is increased. It is suitable for producing various chemical polypropylene pipes and fittings, good anticorrosion effect.
