Firstly, silica gel belongs to rubber material, while PVC belongs to plastic material. The main material of PVC pipe is polyvinyl chloride, and the main raw material of silicone pipe is silicon dioxide.
1, silicone hose, silica gel material chemical performance is stable, in addition to strong alkali, hydrofluoric acid does not occur with any chemical substances chemical reaction, good chemical performance, good electrical insulation performance, not easy to aging weather resistance, soft material up to 330 degrees to -40 degrees, environmental protection non-toxic material, colorless and tasteless. The domestic pipe will be made of silica gel material, which is mainly used in household appliances, medical industry, industrial industry, automobile industry and so on.
2, PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricant with hot pressure injection molding machine extrusion molding, main performance, electrical insulation; Good chemical stability; Self-extinguishing; Low water absorption; Easy to stick, the highest temperature resistance of 40°. Main appliances industrial gas, liquid delivery, household sewer pipes, water pipes and so on. Environmental protection problems: the plasticizer, antioxidant and other main auxiliary materials are toxic. The plasticizer in PVC plastics for daily use mainly uses dibutyl terephthalate, dioctyl phthalate and so on. These chemicals are toxic.
