In the daily use of PVC lay flat hose, there are PVC lay flat hose, polyurethane lining PVC lay flat hose, rubber lay flat hose and so on. What are their differences?
1. PVC LAY FLAT HOSE is not resistant to high temperature, variability and odor. Rubber lay flat hose can resist high temperature, aging and long service time. Polyurethane PVC lay flat hose has higher application fields of corrosion resistance, acid and alkali resistance and freeze resistance. Rubber has better elasticity than PVC, which belongs to plastics.
2. The raw material of PVC LAY FLAT HOSE is actually a kind of vinyl polymer, and its material is a kind of non-crystalline material. In the practical use of PVC materials, stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives are often added.
It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for the occasion of contacting aromatic hydrocarbons and chlorinated hydrocarbons.
