Teflon plate It is known as the "King of Plastics" in the field of plastics. Its performance is better than ordinary plastics. PTFE board Its heat resistance and chemical stability are better than ordinary plastics, even in aqua regia; teflon plate Its appearance is the primary color of pure white resin, but in order to improve its performance, graphite, molybdenum disulfide, carbon fiber, etc. can be added to form a black filled polytetrafluoroethylene board, or polystyrene resin can be added to brown the soil, or glass fiber can be added to form a gray 5mm polytetrafluoroethylene board, sometimes various fillers can be added in proportion.

After various fillers are added, various filled polytetrafluoroethylene plates that meet the performance requirements can be produced, so that the wear resistance, anti-static, creep resistance, mechanical properties and machining The performance has been greatly improved. Therefore, PTFE board can be used for stair board, bridge support, bearing slider, seal, stamping gasket and mechanical guide rail, electrical insulation material, lining in contact with corrosive medium, rail seal and lubrication material, among which PTFE stair board is widely used. But, you know Teflon The quality of stair board is divided into pure material, grade a material and grade B. So, do you know what's the difference between pure tetrafluoroethylene stair board and Grade A tetrafluoroethylene stair board? Next, Liangshan Teflon will tell you.

The quality of PTFE stair board can be divided into pure materials, Grade A materials and Grade B materials, because the raw materials of PTFE can be divided into new materials and recycled materials. The polytetrafluoroethylene products produced with new materials are new materials, and the product performance reaches or exceeds the national standard products. Recycled materials are recycled tetrafluoroethylene materials, which are processed by special grinding, cleaning and other processes, and can be mixed with new materials, which determines that the performance characteristics and application range of different PTFE stair boards are different. The pure material is brand new, and the product performance reaches the national standard. It has excellent corrosion resistance, temperature resistance, sliding and non bonding properties. Grade A plate can be used in different occasions, with slightly lower cost. The product performance is different from that of pure material products.

It is worth noting that if the PTFE plates are distinguished according to the performance difference, the PTFE plates are mainly PTFE I type plates, II type plates and III type plates. Among them, the recycled polytetrafluoroethylene powder, also known as new material plate, cannot be added to Class I plate, which is suitable for enterprises with relatively standardized use requirements and strict quality requirements; Type II and III plates can be used in various occasions without adding or adding appropriate amount of recycled PTFE powder.
