?In modern engineering plastic applications,PBT (polybutylene terephthalate) materials are widely used in many key fields such as electronics, automobile manufacturing, aerospace, etc. due to their excellent mechanical properties, good chemical corrosion resistance and excellent molding processability. However, the inherent flammability of PBT materials severely limits their use in scenarios with extremely high fire safety requirements. In order to effectively solve this problem and meet the strict requirements of PBT materials passing the glow-wire test and achieving halogen-free flame retardancy, Yicheng Flame Retardant has launched two effective halogen-free flame retardant solutions based on its deep technical accumulation and continuous innovative research and development.

Red phosphorus masterbatch flame retardant solution

?

?Red phosphorus masterbatch is a highly effective halogen-free flame retardant.It plays a key role in the flame retardant modification process of PBT materials. In practical applications, when 13-15 parts of red phosphorus masterbatch are added to PBT materials and the PBT fiber ratio reaches 30%, the material can successfully reach the V0 flame retardant grade of 1.6mm thickness in the UL94 standard. More importantly, the PBT material with such a ratio can easily pass the 750℃ glow wire test. This means that in a simulated high temperature and high-risk use environment, PBT products will not cause continuous combustion due to contact with the glow wire, which builds a solid fire safety line for the actual application of the product.

?

IfThe flame retardant properties of PBT materials have higher standards, such as the expectation of passing the 850℃ or even 960℃ glow-wire test. After a lot of experiments and practical verification by the technical team of Yicheng Flame Retardant, it was found that this goal can be achieved by adding an appropriate amount of specific additives on the basis of using red phosphorus masterbatch. However, from the perspective of the wide application in the market, the 750℃ glow-wire test standard is already relatively common in many industries and can meet the basic requirements of the fire retardant properties of PBT materials in most scenarios.,thinkFor more detailed usage ratios and plans, pleaseContact our customer service ormessage。

Inorganic aluminum hypophosphite masterbatch flame retardant solution

?

? ?Inorganic aluminum hypophosphite masterbatch is alsoPBT is the best choice for halogen-free flame retardant, aluminum hypophosphitePhosphorus content up to80%, which gives inorganic aluminum hypophosphite masterbatch excellent flame retardancy. Generally, adding 15-17 parts of inorganic aluminum hypophosphite masterbatch to PBT material can make the PBT material reach V0 flame retardancy level at 1.6mm thickness, and under the condition of 750℃ glow wire test, it can ensure that the material does not burn throughout the whole process, showing excellent flame retardant effect.

?

When requestedWhen PBT material passes the 850℃ glow wire test, the amount of inorganic aluminum hypophosphite masterbatch added needs to be increased to about 18-20 parts. However, it is worth noting that with the increase in the amount added, the physical properties of the PBT material will be affected to a certain extent. This requires the professional team of Yicheng Flame Retardant to comprehensively and in-depth consider the customer's specific requirements for the flame retardant properties, physical and mechanical properties of PBT materials when formulating flame retardant solutions for customers.,thinkFor more detailed usage ratios and plans, pleaseContact our customer service ormessage。
