When it is through nebulization, such as for patients, it is often difficult to guarantee the dose. And has very mechanical properties. In our country, plastic parts account for about 7%-10% of the car’s own weight. 3. When 30% glass fiber is added to PA, the mechanical properties, dimensional properties and heat resistance of PA66 are obvious, and the fatigue strength is 2.5 times stronger. Among them, there are many applications in the automotive field. ,
Material performance
1. It is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt adhesion is enhanced, the melt viscosity is decreased, and the performance is unchanged compared with polytetrafluoroethylene. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods.
2. The long-term use temperature is -80-260 degrees. It has excellent chemical resistance, corrosion resistance to all chemicals, the lowest friction coefficient among plastics, and good electrical properties. Its electrical insulation is not affected by temperature. Influence, known as the “Plastic King”.
3. Its chemical resistance is similar to polytetrafluoroethylene and better than vinylidene fluoride.
4. Its creep resistance and compressive strength are better than PTFE, with high tensile strength and elongation of 100-300%. Good dielectric properties and excellent radiation resistance. High flame retardancy.
5. Non-toxic: It is physiologically inert and can be implanted into the human body.
V0 level
1. Suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, sealing parts, insulating parts and parts.
2. High-temperature wire and cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
Molding performance 1. Crystalline material, low moisture absorption. It can be processed into products by the usual processing methods of thermoplastics.
3. Poor fluidity, easy to decompose, and produce corrosive gas during decomposition. It is advisable to strictly control the molding temperature not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the pouring system should have low resistance to material flow.
4. Translucent pellets, injection molding and extrusion molding. The molding temperature is 350-400 degrees, and the temperature above 475 degrees is likely to cause discoloration or bubbles. And note that demolding will be more difficult.
5. Because the molten material has a corrosive effect on the metal, the mold needs to be electroplated with chromium for long-term production.
PFA FEP PTFE has similar chemical properties, but FEP can only be used below 200 degrees, and PTFE cannot be injection molded.

This black body film material can radiate energy in the form of far-infrared electromagnetic waves to achieve the effect of cooling. However, after filling with glass fiber or filler, its elongation is greatly reduced, and if there are depressions in the product, forced demolding cannot be implemented. It has strong ability to absorb shock, stress and vibration, and its impact strength is much higher than that of general plastics, and it is better than acetal resin. The corrosion resistance of PA66+GF is also remarkable, which can meet the requirements of automobile radiator groove, radiator middle part bracket, water inlet pipe fittings, oil pan, oil filled tank, oil level gauge, automobile water chamber, etc. 4) If the cross-sectional area of the gate or runner is small and long, the melt pressure loss is large, the flow resistance is large, and the flow is prone to poor flow and insufficient filling. For this, correct and pour.
