At present, the automobile and home appliance industries are hot spots for the development of modified plastics, and both account for more than 50%. Xuzhou Tengfei Engineering Plastics is a high-tech enterprise specializing in the R&D, production and sales of engineering plastics, strong nylon and modified engineering plastics. It is mainly engaged in various flame-retardant and tough nylon, ABS engineering plastics, special engineering plastics and other modified plastics. Hotline:. However, some special fillers that are unique or directly added to the surface will not cause a decrease in the tensile strength, but will increase the tensile strength to a certain extent. We call this type of fillers as reinforcing fillers. Figure 4.5 is the DSC curve of PA66 and FR-PA66.
Polyvinylidene fluoride
Poly (vinylidene fluoride), the English abbreviation PVDF, mainly refers to vinylidene fluoride
Pvdf molecular formula ethylene homopolymer or copolymer of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. It combines the characteristics of fluorine resin and general resin, besides having good chemical corrosion resistance, high temperature resistance, and oxidation resistance In addition to weather resistance and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties. It is the second largest product among fluorine-containing plastics. The global annual production capacity exceeds 53,000 tons.
In the chemical structure, a fluorine-carbon bond is used. This structure with short bond properties forms the most stable and strongest bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only have strong wear resistance and impact resistance, but also have high fading resistance and UV resistance in extremely harsh and harsh environments.

If the product requirements are high, we must consider a dehumidifying dryer to solve the problem. The disadvantage of metal materials is the hardness and size of the material itself, but the unmodified PA66 material does not match the aluminum alloy in the tensile strength and hip sling stool. The molded parts of semi-crystalline plastic materials have high shrinkage rate. This makes the problem of dents more serious; non-crystalline materials have lower molding shrinkage, which will reduce the dents to a degree; materials that are filled and maintained strong have lower shrinkage and are less likely to produce dents. 2. High mechanical strength, small deformation under long-term load; 3. Low water absorption, good size and excellent wear resistance.
In addition, the heat resistance and size of the composite material are very large, and it has a professional VOC odor detection laboratory. Its application in aircraft, rockets, and other vehicles that require weight reduction is extremely important. At present, the amount of polyurethane used in the plastics for children’s bicycles is 20%, and that of foaming materials for vehicles is up to 60%. Strong nylon materials that have been stretched orientated often contain some γ-crystals. There are many types of nylon in the future: PA6, PA66, 610, PPA, PA1010 and so on. Modified nylon is filled with multiple physical properties to achieve the fatigue strength, rigidity, heat resistance, coefficient, wear resistance and other properties of nylon. . 2. Halogen-free flame retardant can not only give the flame-retardant material a better overall balance in terms of performance, but also has a wider applicability in color. Therefore, halogen-free flame retardant technology has gradually become popular. To put it vividly, this kind of plastic is an extremely cold energy transmission channel at room temperature and minus 270°C in outer space where we live, and it can continuously transport out the heat that is not available on the earth.
