As a rubber hose for automobiles, the performance of PVC and silica gel and their acquaintance, so the role and direction are basically acquainted, so how do they distinguish in the car?
PVC pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot press injection molding machine. Main performance and electrical insulation; good chemical stability; self-extinguishing; low water absorption; easy bonding, Can withstand high temperatures of about 40 °. Main equipment industrial gas, liquid transportation, etc., household sewer pipes, water pipes, etc. Environmental protection issues: Additives such as plasticizers and anti-aging agents are toxic. Plasticizers in daily-use polyvinyl chloride plastics mainly use dibutyl terephthalate and dioctyl phthalate. These chemistries The product is 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. The silicone tube is widely used, and the silicone tube for automobile will be the direction of development of the silicone tube.
The main part of the silicone tube in the car is: engine, transmission brake, drive, pressure transmission, etc. In addition, automotive silicone tube manufacturers can also choose different material performance hoses, such as medical silicone hose, food grade environmental protection silicone tube , industrial pipe, silicone shaped tube, silicone tube fittings, etc.
