    What Are the Effects of Sunlight on PVC? It It UV Resistant?

    22/10/2013· The quick and easy answer is, no, not really. PVC does surprisingly well when exposed to ultra violet rays sunlight. Research shows little to no effect on PVC''s tensile strength or elasticity after prolonged sun exposure. The only degradation that seems to occur is impact strength.

    UV Properties of Plastics

    PTFE has particularly good UV resistance because it has the very strong carbon-fluorine C-F bond almost 30% higher than the carbon-hydrogen C-H bond, which is the common side bond that surrounds the carbon C-C backbone in the helix and protects it.

    PE vs PVC: What is the Difference & Which Should I PE100

    Because PVC is sensitive to UV light, if it is used above ground, it should contain stabilizers and UV inhibitors and may require painting with a water-based latex paint. Due to its rigidity PVC pipe cannot be coiled and has to be transported in rigid segments.

  • Puhui HDPE pipe and fittings

    Difference Between HDPE and PVC Difference Between

    PVC is heavier and stronger while HDPE is harder and more abrasion and heat resistant. 5.HDPE pipes are found to be able to dampen and absorb shock waves minimizing surges that can affect the system while PVC cannot. 6.HDPE is more suitable for lower

    Difference Between PVC and HDPE Compare the PE100

    14/7/2016· PVC and HDPE are two types of polymeric synthetic plastic materials which are used in many industrial appliions. The key difference between HDPE and PVC is the difference in density; HDPE is denser than PVC, and this leads to differences in their physical properties and industrial appliions. In addition, the difference in chemical structure Puhui Pipe manufacturer in China
