Puyang Adiprene Duracast E530 D PUR-aliphatic/MDI material report,
The fourth is to adhere to the market orientation and promote happily. Mainly the hardness, modulus and tensile strength decrease, yield point and impact strength increase. HDT is at 305, downstream demand is weak, and actual transactions are not many. At the macro level,
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 strong 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.

Because the appearance is the first to cool and fix the shape, the surface treatment of the glass fiber is generally processed during the production of the glass fiber. Modified plastics are one of the important lightweight materials for automobiles. While reducing the weight of automobiles, they also significantly increase the production cost of automobile manufacturers. The modified plastics industry, as a sub-industry with rapid development and great development potential in the plastic processing industry, is expected to maintain a growth rate of more than 10% in the total market demand in the next five years. It is worth noting that for different toughness systems, organic rigid materials have different toughness effects. For non-pre-toughened matrix systems, the toughness range of organic rigid particles is small.
Although mineral fillers have replaced the base plastics on a one-to-one basis, 3 additional functions affect the price of strong nylon. When requested, the construction will be centered on the polymer material Mouxun, which is centered on Xuzhou. , 2: High-performance engineering plastics. In addition, modified nylon 66 is also widely used in making toys, sports goods, etc. In the direction of the white edge, the white edges are still swollen and connected, so the white edges are not cracks. Under proper heating, it is possible to restore the stretch-oriented molecules to their natural curling state and make the white edges fade. However, the general PP material has large shrinkage rate, poor product size, and is prone to warping deformation; it is easy to brittle at low temperature, and has poor low temperature toughness; it has disadvantages such as poor light aging resistance and heat aging resistance. No matter which one is not good, 6. High temperature resistance or low temperature performance and heat resistance are good.
