PVC profile is PVC products that are squeezed out of high -temperature extrusion after adding various functional additives by PVC resin.It can be divided into two types: hard and soft.Hard PVC profiles are mostly used in buildings, such as making PVC doors and windows, PVC flooring, PVC pipes, etc.; soft PVC profiles are used for PVC hose, transmission cables, etc.
National Standards for PVC Classification
In fact, the national standard of PVC is the use of various PVCs.Let ’s list it in detail: GB3806-83 Polyvinyl chloride plastic sandals GB3807-83 Polyvinylene Micro-Pole Plastic slippers GB3830-83 soft polyvinyl chloride compression film (tablet) GB4085-83 semi-hard polyvinyl chloride block shapePlastic flooring GB4219-84 Hard polyvinyl chloride tubing
PVC profile density
The relative density of PVC profiles is 1.35-1.46, and the refractive index is 1.544 (20 ° C). It is insoluble in water, gasoline, alcohol, and chlorolythene, but organic solvents such as pedone, dichloroethane, diomyne, and other organic solvents;Some factories, laboratory.And PVC profile density is greater than water, and many floating objects cannot use PVC profiles.
PVC profile processing
Due to the poor ductility of PVC, it is easy to cause the melt breakdown, and the PVC melt is relaxed, and it is easy to cause the disadvantages such as rough surfaces and no lightness.Therefore, in order to improve the flaws of its melt, the processing assistant is often added when processing PVC.There are three main ways of processing auxiliary agents: promoting resin melting, improving melt flowing performance, and giving lubrication performance.
PVC profile price
Because PVC profiles can make various required industrial materials that can be made through high temperature and corresponding templates through high temperature and corresponding templates. The process is quite complicated.With the scarcity of this PVC resin, suppliers have increased the cost price of purchases. As the manufacturer rises in the manufacturing process, it has also been shared into the materials made, and the price is too high.
PVC profile formula
PVC resin, a polymer with a strong molecular force.Generally, white powder, no toxic, no odor, cannot be dissolved in water.However, at a very high temperature, there will be a pungent odor. This gas is hydrogen chloride. This gas is toxic and is easily soluble in water. It will be absorbed by the human body and cause poisoning.
