The difference between rubber hose and PVC garden hose
garden hose with a lot of choice of materials, rubber material, PVC material, what is the difference between the two? Let’s take a look at it:
PVC is not rubber, should belong to plastic. Plastic is generally harder, rubber is generally more soft, but this is not absolute. PVC soft is a special case. Because PVC soft feeling like rubber, in fact, it is not rubber. Rubber is divided into natural rubber, styrene butadiene rubber, chloroprene rubber, butadiene rubber, nitrile rubber, silicone rubber, etc., nearly 20 kinds of rubber is a kind of polymer material, high temperature elasticity at room temperature is rubber material alone There are features that are not available in any other material, so the rubber is also called the elastomer. The performance of the high elastic material is that it has a large elastic deformation under external force, up to 1000%, and the deformation is quickly restored after removing the external force, while the deformation of the metallic material with only elasticity is only about 1%.
