Description
Technical Field
The invention relates to the technical field of high cold-resistant PVC films for vehicles, in particular to a high cold-resistant PVC film for vehicles.
Background
The PVC mainly contains polyvinyl chloride, is yellowish, semitransparent and glossy. The transparency is better than that of polyethylene and polypropylene, is different from that of polystyrene, is divided into soft and hard polyvinyl chloride according to different using amounts of the auxiliary agents, soft products are soft and tough, the hand feeling is sticky, the hardness of hard products is higher than that of low-density polyethylene and lower than that of polypropylene, and the whitening phenomenon can occur at the bending position. Common preparations: plate, pipe, sole, toy, door and window, wire sheath, stationery, etc. Is a high molecular material which uses a chlorine atom to replace one hydrogen atom in polyethylene.
PVC can be divided into soft PVC and hard PVC. With hard PVC accounting for approximately 2/3 on the market and soft PVC accounting for 1/3. Soft PVC is generally used for floors, ceilings, and leather surfaces, but the soft PVC contains a softening agent (which is a difference between soft PVC and hard PVC), and thus is easily brittle and not easily preserved, so that the range of use thereof is limited. The hard PVC does not contain a softening agent, so the hard PVC has good flexibility, easy forming, no toxicity or pollution and long storage time, is not easy to become brittle, and has great development and application values. Hereinafter referred to as PVC. The essence of PVC is a vacuum plastic film, which is used for surface layer packaging of various panels, so the PVC film is also called as a decorative film and an adhesive film, and is applied to various industries such as building materials, packaging, medicines and the like. The building material industry accounts for 60% of the maximum proportion, the packaging industry is the second one, and other industries with small application range are also provided.
