Silicone rubber is a new type of polymer elastic material, which has excellent high temperature resistance (250-300℃) and low temperature resistance (-40-60℃), good physiological stability, excellent resilience and small permanent deformation (less than 50% at 200℃ for 48 hours) and breakdown voltage (20-25kV/). Radiation resistance and other characteristics, special silicone rubber has oil resistance. Silicone hose is also a kind of hose, which is oil-resistant and heat-resistant. Because of the different types of rubber, rubber pipes have many applications. Commonly used hose materials are EPDM, CR, VMQ, FKM, IIR, ACM, AEM, etc. Common structures are single-layer, double-layer, multi-layer, reinforced and unreinforced. The biggest feature of silicone hose is that it can resist the temperature change from -60 degrees to 250 degrees, but the cost is very expensive. Pvc is often used as a common water pipe, which is sensitive to temperature, cheap and delicious, suitable for general working environment, and has no requirements for hoses. Pressure-resistant silicone hose can withstand pressure, PVC in general, depending on wall thickness and caliber. This is the difference between silicone tube and PVC tube.
