Strong nylon, strong nylon, flame-retardant nylon manufacturers introduce the structure of strong nylon and the cleaning and antifouling properties of strong nylon: What affects these two properties is the cross-sectional shape of the fiber and some antifouling treatments in the subsequent process. A 45/5/32L reverse shear block is added to the front section of the 3# screw, which can effectively disperse and toughen the toughening agent, so that the notched impact strength has been significant. 4. Filling modification is one of the core technologies of modified plastics. Blending and compounding improve the hardness of plastics Blending to improve the hardness of plastics The improvement of plastic blending means mixing high-hardness resins with low-hardness resins to increase the hardness of the body. It is obvious that PA66 fiber addition can be seen as a strong modification by adding glass fiber on the basis of PA66 original package.
The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP, is a class of chemical substances. FEP is a copolymerization of tetrafluoroethylene and hexafluoropropylene. FEP crystal melting point is 304℃, density is 2.15g/CC (grams/cubic centimeter).
FEP can be applied to soft plastics, and its tensile strength, abrasion resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant (2.1) over a wide temperature and frequency range.

Modified plastics, as an important part of the field of new chemical materials, have also been listed as one of the key scientific and technological fields for development. At present, the materials used in sports equipment are mixed use of a variety of materials, and the application of plastics and their composite materials is expanding. In the Kobe earthquake in 1995, the pipes that did not cause large-scale damage were PE gas pipes and water supply pipes. It has high impact strength, high rigidity, fatigue resistance, abrasion resistance, good internality, and its unit strength is comparable to that of metal. When the content of glass beads reaches 18%,
It also has many kinds of processing, such as blow molding, extrusion, injection molding, spinning and so on. PC alloy applications: automotive instrument panels, computers and office automation equipment, power tool housings, cellular phones, etc. A monofunctional compound is added as a molecular weight regulator, and a monofunctional compound is added as a chain end. In the slightest, the printing ink will be partially dyed, and the film will not be uncovered and will be discarded directly. With the accelerated pace of the household appliance industry replacing steel with plastics in the future, its demand for plastics will be even greater. In addition, some office equipment, optical devices and some daily necessities often use PPS instead of metal and thermosetting plastics. Experiments have proved that the inorganic powder filled modified plastic can not only save the amount of resin, save petroleum resources, raw material costs, pollution, and for packaging materials and tableware that are not easily recycled, it can be filled with inorganic powder under the guarantee of practical performance and hygienic conditions. When it reaches more than 30%, it is easier to be absorbed by nature after being discarded. Especially in the field of injection molding, PBT is used in automotive and electrical-electronic applications, and its performance requirements are various. It is polar and will attract each other due to the action of hydrogen bonds.
