Characteristics of PVC hose
The main component is polyvinyl chloride, which has bright color, corrosion resistance, firmness and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., it is The product generally does not store food and medicines. If there are special physical property requirements, an appropriate amount of modifier can be added. However, plasticizers must not be added. They have good tensile and compressive strength, but their flexibility is not as good as other plastic pipes, and their corrosion resistance is excellent. The price is the cheapest among all kinds of plastic pipes, but it is more brittle at low temperatures. Rubber ring connection and flange thread connection are used for water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. in residential life, industry and mining, and agriculture. Outstanding heat resistance, heat distortion temperature of 100 ℃, excellent chemical resistance, bonding, flange thread connection of hot water pipes.
