PVC plastic revolution history brief

A Brief History of Revolutionary History of PVC Plastics

PVC profiles, although some of the natural materials do not have the unique performance, but also have low strength, poor heat resistance and linear expansion coefficient and other defects, so in the production of doors and windows profile often need to be enhanced. The general method of reinforcement is in the profile of the cavity into the metal material, the second enhancement, the current market, the so-called “steel doors and windows” are almost all produced in this way. However, this enhancement method can not fundamentally solve the problem, therefore, how to enhance the material and PVC for one-time composite extrusion processing has been the subject of research. Foreign technology in this area is more advanced, already

PVC profiles, although some of the natural materials do not have the unique performance, but also have low strength, poor heat resistance and linear expansion coefficient and other defects, so in the production of doors and windows profiles often need to be enhanced. The general method of reinforcement is in the profile of the cavity into the metal material, the second enhancement, the current market, the so-called “steel doors and windows” are almost all produced in this way.

However, this enhancement method can not fundamentally solve the problem, therefore, how to enhance the material and PVC for one-time composite extrusion processing has been the subject of research. Foreign technology in this area is more advanced, has already launched a steel-plastic composite, aluminum-plastic composite, wood-plastic composite profiles. These composite profiles are mainly used for structural materials and load-resistant components in addition to doors and windows. There are manufacturers also introduced a composite steel doors and windows, can be described as worthy of the “steel” doors and windows.
