PBT flame retardant grade

The following are the same as the " PA6 flame retardant grade / conductive grade

Flame retardant: to the ordinary plastic resin inside the addition of flame retardant, you can make the plastic flame retardant properties, flame retardant can be one or several flame retardant composite system, such as bromine + antimony, phosphorus, nitrogen Series, silicon, and other inorganic flame retardant systems.

Conductive nylon 66: has good wear resistance, heat resistance, oil resistance and chemical resistance, but also greatly reduces the raw material water absorption and shrinkage, with excellent dimensional stability and excellent mechanical strength. To meet the static Dissipation and electrostatic discharge (ESD) protection. These special modified materials are specially formulated for use in the range of 100 to 1012 ohms / square (ohms / sq) surface resistance, which can be used for injection molding and extrusion molding. Advantages of metal and coating: parts are lighter in weight, easier to handle, and have lower transport costs. They are easy to assemble, have lower manufacturing costs, and are less likely to be hit, cut and scratched. Purpose, some materials can be pre-dyed to avoid time-consuming and expensive two-color processing.

Unmodified nylon has poor flame retardancy, its vertical combustion can only reach UL94 V-2 level , oxygen index of 24 or so, and in the combustion process to produce drip, are flammable materials, in the course of the use of the pole It is easy to cause fire.Especially in the field of electronic products, due to the fire caused by nylon countless, resulting in large losses, therefore, the nylon flame retardant modification of today's academic and industry common concern and research topics.

The widely used halogen-free flame retardants in nylon are red phosphorus and melamine salts. Red phosphorus has a high flame retardant efficiency and can improve the arc resistance of the product, but its storage and color limitations greatly limit its The application in nylon is generally only applied to nylon 6. Another halogen-free flame retardant used in nylon is melamine salt, mainly melamine urate and phosphate, which have good flame retardancy.

In order to meet the requirements of the development of related industries.Therefore, must be for a particular application area, through modification, improve its performance, to expand its application areas. Mainly in the following aspects of modification.

① improve the water absorption of nylon, to improve the dimensional stability of products.

② to improve the flame resistance of nylon to meet the electronics, electrical, communications and other industries.

③ to improve the mechanical strength of nylon in order to achieve the strength of metal materials to replace the metal

④ to improve the anti-low temperature performance of nylon, and enhance its ability to resist environmental strain.

⑤ improve the wear resistance of nylon to meet the requirements of high wear and tear occasions.

⑥ improve the antistatic properties of nylon to meet the requirements of mining and its mechanical applications.

⑦ improve the heat resistance of nylon to adapt to the field of high temperature conditions such as automotive engines.

⑧ reduce the cost of nylon, improve product competitiveness.

In short, through the above improvements, the realization of nylon composite materials , high performance and functional, and thus promote the relevant industry products to high-performance, high-quality direction.
