PP, PE, PET and PVC are four common plastic materials, and there are some differences in their chemical structure, physical properties and application fields.
PP material: Polypropylene is a white and translucent polymer material. It has excellent heat resistance, corrosion resistance, tensile strength, hardness and rigidity. It is often used to make food packaging boxes, medical devices, furniture, auto parts, textiles and so on.
PE material: polyethylene, which is a white or transparent polymer material. It has excellent flexibility, pressure resistance, wear resistance, corrosion resistance and heat insulation. It is often used to make plastic bags, plastic bottles, water pipes, wires and cables.
PET material: polyester, which is a transparent polymer material. It has excellent heat resistance, corrosion resistance, tensile strength and rigidity. It is often used to make beverage bottles, food packaging boxes, fibers, clothing, auto parts and so on.
PVC material: polyvinyl chloride is a white or transparent polymer material. It has excellent corrosion resistance, sound insulation, heat insulation, flexibility and plasticity. It is often used to manufacture building materials, wires and cables, water pipes, floors, curtains, artificial leather and so on.
As for the question whether it is necessary to make anti-skid strips for stairs, the answer is yes. As an important passage connecting different floors, the safety of stairs is very important. With the passage of time, the surface of stair tread tends to become smooth, especially in places with high traffic, and this smoothness will be more obvious. In addition, weather conditions such as humidity, rain and snow will also aggravate the slipperiness of stair steps, thus increasing the risk of falling and slipping. The installation of anti-slip strips is precisely to effectiv transformation of economic growth mode, if the core technology development ability of enterprises is in a leading position, it will open up new paths for the sustainable development of the entire plastic footwear industry.
