What is the size of the PVC pipe joint?
The molecular weight of PVC in industrial production is generally in the range of 5~12 million, with great polydispersity, and the molecular weight increases with the decrease of polymerization temperature. Without fixed melting point, 80~85 began to soften at 130 degrees C and became viscoelastic at 160~180. Its tensile strength is about 60MPa, the impact strength is 5~10kJ/m2, and it has excellent dielectric properties. The stability of the light and heat is poor, at 100 degrees above or after a long time of sunlight exposure, it will be decomposed and hydrogen chloride, and automatically catalytic decomposition, causing discoloration
In practical applications, stabilizers must be added to improve the stability of the heat and light. PVC is very hard and can only be dissolved in a few solvents such as cyclohexanone, two dichloroethane and tetrahydrofuran. It is stable for organic and inorganic acids, alkalis and salts, and the chemical stability decreases with the increase of the use temperature.
[1] the PVC joint size is in inches, 1 inches =25.4 millimeters.[2] PVC: polyvinyl chloride (English: PolyVinyl Chloride abbreviation: PVC) is a use of a chlorine atom to replace one of the hydrogen atoms in polyethylene polymer material. PVC is an amorphous white powder with less degree of branching
