Today, we mainly share polypropylene, which is the raw material of hollow plate, and isoprene in polypropylene resin, which is a kind of well-structured high crystallinity (high crystallinity) thermoplastic resin. Polypropylene itself has the following characteristics:
1.polypropylene is a milky waxy substance, non-toxic, tasteless and odorless, with a density of 0.90~0.91g/cm
2.The mechanical strength, rigidity and stress cracking resistance of polypropylene are better than that of high-density polyethylene.
3.The chemical stability of polypropylene is good, except that the strong oxidizing acid (such as fuming sulfuric acid and nitric acid) has corrosion effect on it, and it has no effect on most chemical drugs. It is insoluble in water and almost does not absorb water. It only absorbs 0.01% of water for 24 hours in water.
4.Good electrical insulation performance, good voltage and arc resistance.
5.The transparency of polypropylene products is better than that of high-density polyethylene products.
6.Metal materials rust while plastics do not.
So plastic hollow board plastic material has the advantage of light quality, color variety, corrosion resistance, high strength, excellent electric properties and processing more easily than forming etc., and as a new type of material, plastic hollow board is restructured as part of the packaging logistics industry, and the environmental protection product is very highly regarded by its state, its development much faster than the other industries, has been in the top spear.
At present, the application field of hollow slab is gradually expanding, and it has been involved in all aspects of national economy and even People's Daily life, such as replacing wood, steel, aluminum, copper, ceramics, glass, leather and paper with plastic.
Hope that more people know the material of plastic hollow board, understand it, so as to use it safely, play its due product function.
Any inquiry,kindly please call me.
