How do you choose between PVC hose and silicone tube when selecting materials? Automobiles have long been an indispensable means of transportation for us. In order to ensure the efficient operation of automobiles, it is necessary to strictly control the selection of parts and materials to determine which material is more suitable. The role of pipe in the car is of paramount importance.

The function of the hose is mainly to transport gas, liquid, paddle or particulate matter, and the materials selected in different materials and different environments naturally differ. However, as a rubber hose for automobiles, PVC and silica gel have similar properties. So how do they distinguish between cars? The following is a professional hose manufacturer to introduce the characteristics of PVC hose and silicone tube.

PVC pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot press injection molding machine, electrical insulation; good chemical stability; self-extinguishing; low water absorption; easy bonding, high temperature resistance 40° or so. However, PVC materials have environmental problems, and the main auxiliary materials such as plasticizers and anti-aging agents are toxic. The plasticizers in daily-use polyvinyl chloride plastics mainly use dibutyl terephthalate and dioctyl phthalate. Etc., these chemicals are toxic.

Silicone rubber is a polymer material. It differs from PVC in that the basic properties of the material on the body are enhanced, and the high temperature resistance (250-300 ° C) and low temperature resistance (-40-60 ° C) have certain physiological stability. Moreover, it can withstand repeated harsh and disinfection conditions, has excellent resilience and permanent deformation (200 ° C 48 hours no more than 50%), breakdown voltage is (20-25KV / mm), ozone resistance, UV resistance . Features such as radiation resistance, special silicone rubber has oil resistance. Compared with PVC pipe silicone products, it has the advantage of being safe and non-toxic, so the silicone tube for automobiles will be the direction of vigorous development in the future.

The silicone hoses produced by our company are mainly used in automobiles: engine, transmission brake, drive, supercharged transmission and so on. In addition, our company can also provide different performance silicone tubes, such as medical silicone hose, food grade environmentally friendly silicone tube, industrial tube, silicone shaped tube, silicone tube fittings and so on.
