The main component of PVC is polyvinyl chloride, which is light yellow and translucent.Transparency is better than polyethylene, polypropylene, difference in polystyrene, along with the different dosage of additives, can be divided into soft and hard polyvinyl chloride (PVC), soft soft, tough, feel sticky, hard ware hardness is higher than that of low density polyethylene, but lower than that of polypropylene, can appear in the inflectional bleaching.Common products: board, pipe, sole, toys, doors and Windows, wire covers, stationery, etc.A polymer material that USES a chlorine atom instead of a hydrogen atom in polyethylene.
What is the difference between PVC film and ordinary adhesive film?The common adhesive film is used to stick glue directly to the surface of the board at room temperature, so after one or two years, the adhesive film is easy to fall off.And PVC film is used special vacuum film press in 110 degrees of high temperature pressure attached to the surface of the plate, so it is not easy to fall off.
The PVC membrane has excellent quality assurance, but some people might say, PVC, after all, is a chemical product, it is not nearly as natural material, exclude the toxicity and smell, can harm the environment.The fact is not the case, this is because the German production raw material is specially refined PVC film, toxic substances were extracted from completely, so PVC is completely non-toxic tasteless, no stimulus to human skin or respiratory system, for those people who are allergic to wood and paint, using PVC membrane packing of furniture or kitchen utensils and appliances is very appropriate.By using PVC film as decorative film, people can use a lot of medium density board, particleboard, plywood and fiber board to reduce the amount of wood used, thus reducing the damage to forests and even the environment.From this point of view, PVC film has made a great contribution to the protection of the ecological environment.
The use of PVC once caused great controversy in western countries. Many people tried to replace PVC with various other materials.But it turns out that the quality of PVC is no less than that of other alternatives, and it's cheaper to make than these materials.Research by experts has found that in many industries, abandoning the use of PVC will result in considerable additional costs.The figures show that abandoning PVC would add billions of marks to the cost.For specific consumers, this would mean a huge extra expense.For surface material with PVC Windows, for example, if the window does not use PVC, but use ordinary wood as the surface layer, then just on cleaning and maintenance a increases the cost of a surprising.In a small town in England, people in the past twenty years have used wooden Windows, some of these Windows cleaning and maintenance costs, and to compare it with PVC window cleaning fee, the results show that the ordinary wooden window cleaning fee is more than double that of PVC window cleaning fee.
