< : , r, r Material properties
<:, r, r, long-term use temperature, excellent chemical resistance, corrosion resistance to all chemicals, friction coefficient
<:, r, r is the lowest among plastics, and there are many It has good electrical properties and its electrical insulation is not affected by temperature. It is known as the king of plastics.
<: , r, r, in a transparent or translucent state. The higher the crystallinity, the worse the transparency. The raw materials are mostly powdered resin or concentrated dispersion.
< :, r, r has an extremely high molecular weight and is a thermoplastic polymer with high crystallinity. Suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, seals, insulation parts and medical device parts
< :, r, r Molding properties. Crystalline material, low moisture absorption.
<:, r, r. Poor fluidity, easy to decompose, and generate corrosive gas when decomposed. The molding temperature should be strictly controlled, the mold should be heated, and the pouring system should have small resistance to material flow.
<:, r, r. Powdered resin is often formed by powder metallurgy, using a sintering method. The sintering temperature must not exceed 0. Emulsion resin is usually processed by cold extrusion and then sintering, which can form an anti-corrosion layer on the surface of the article. If the product requires transparency and good toughness, rapid cooling should be adopted. Extrusion molding can also be used, and tubes, rods, and profiles can be extruded.
< :, r, r, the melt viscosity is very high, and the volume viscosity decreases with the increase of shear stress, showing the characteristics of non-Newtonian fluid.
< :, r, r, secondary processing, which can be hot pressing compounding, welding, bonding, reinforcement, machining, etc., to obtain the final product.
<: , r, r (polytetrafluoroethylene) is commonly known as plastic king, or Teflon. It is made of suspended polytetrafluoroethylene resin through molding and can be made into plates, turned films and tubes. Can be pressed and pushed into shape.
<: , r, r can be mixed with graphite to make plates, rods, packings, ropes, and raw material belts. Characteristics: The operating temperature range is very wide (from degrees Celsius to + degrees Celsius). .Basically resistant to all chemicals
< :, r, r except some fluorides and alkaline metal liquids. .Excellent mechanical properties including aging resistance especially for bending and swing applications.
< :, r, r. Outstanding flame retardancy (in accordance with and test procedures, regulated as a flame retardant material in air. Excellent insulation properties (regardless of its frequency and temperature). Very low water absorption ,
< :, r, r and has a series of unique performance applications such as self-lubrication and non-stickiness: sealing gaskets, ring materials, wear-resistant plate seats, insulating parts, corrosion-resistant industries, mechanical parts, Lining, petroleum and
< : , r, r natural gas, petrochemical industry, chemical industry, instrument and equipment manufacturers, etc.
