? ?In the field of plastic products, PP materials have been widely used due to their excellent comprehensive performance. However, with the increasingly stringent safety standards, the demand for halogen-free flame retardant PP materials has become more urgent. So, how can PP materials achieve halogen-free flame retardancy? As a professional organization in the industry, Yicheng Flame Retardant will provide you with a detailed analysis of two effective solutions.

Compounding scheme of red phosphorus powder and magnesium hydroxide

This solution can be used to compound red phosphorus powder with magnesium hydroxide.It has a good flame retardant effect in PP materials. In homopolymer PP, adding 13-15 parts of compound flame retardant can achieve the V0 flame retardant grade in the UL94 standard. For copolymer PP, the addition amount needs to be increased to 16-18 parts, which can also achieve the V0 flame retardant effect. The advantage of this solution is that the processing process is relatively simple, but it should be noted that this solution is only suitable for the preparation of black or red PP products. This is due to the color characteristics of the red phosphorus powder itself, which will have a greater interference with the color in products of other colors.

Phosphorus and nitrogen flame retardant solutions

Phosphorus nitrogen flame retardantHalogen-free flame retardant PP material provides another option, and this solution can achieve flame retardancy of natural PP material. Adding about 20% of phosphorus-nitrogen flame retardant in homopolymer PP and about 22% in copolymer PP can make PP material reach V0 flame retardancy at 1.6mm thickness. However, when using this solution, it is necessary to pay close attention to several key factors.

a.The performance of the processing equipment, i.e. the machine, is crucial. The machine's temperature control, shear force and other parameters will directly affect the performance of phosphorus-nitrogen flame retardants inThe dispersion uniformity in the PP material and the interaction between the flame retardant and the PP material affect the flame retardant properties and physical and mechanical properties of the final product.

b.There must be no residual oxides in the raw materials, especially antimony trioxide substances. These oxides will react chemically with phosphorus-nitrogen flame retardants, causing appearance defects such as graying and yellowing of the products, seriously affecting the quality and appearance of the finished products.
