PU steel wire hose is made of polyurethane raw material. PU is the abbreviation of Polyurethane. The Chinese name is polyurethane. PU steel wire hose is widely used in glass, wood industry, steel industry, plastic industry, pit, shipbuilding industry, cement industry and other mechanical conveying pipes for use in environments requiring high friction. At the same time, food grade PU steel wire hose can also be used in food, pharmaceutical, beverage and other industries. PU steel wire hose can better meet the wear-resistant transportation requirements of various industries.
PVC steel wire hose is made of PVC synthetic material. High-strength galvanized metal wire is spirally embedded in the inner wall of the flexible PVC hose.
On the surface, the difference between PU steel wire hose and PVC steel wire hose is not very large, both are transparent. One uses copper-plated steel wire, and the other uses galvanized steel wire. Both are embedded with steel wire. There are huge differences between the two. There are the following differences:
1. From the point of view of material, steel wire hose made of PU polyurethane material is more pure and transparent than PVC steel wire hose. The steel wire embedded in PU steel wire hose is copper-plated steel wire or stainless steel wire, which is more than PVC galvanized steel wire. Wear-resistant and stretch-resistant, and the steel wire of PU steel wire hose is thicker than that of PVC steel wire hose, which greatly prolongs the service life of PU steel wire hose.
2. In terms of service life, the service life of PU steel hose is 7-10 times that of PVC steel hose.
3. From the perspective of physical and chemical properties, PU steel wire hoses have high corrosion resistance, pressure resistance, wear resistance, and high temperature resistance. These are far less than PVC steel wire hoses. It will not harden at very low temperatures in winter, and will not soften or yellow at very high temperatures in summer. These are also unmatched by PVC steel wire hoses.
