The production of PP sheet usually uses homopolymer PP raw materials, copolymer PP raw materials, etc., and according to the needs of users use different materials. The properties and results are also very different.
Yinsu company prepared expanded flame retardant PP composites by melt mixing method, studied their thermal stability and flame retardant properties, and combined with high-resolution electron microscopy and Raman spectroscopy analysis of carbonized products.
Aluminum hypophosphite is widely used in flame retardants, due to its good thermal stability, easy dispersion, does not contain halogens and other advantages.
The features we should consider before choosing the flame retardant includes: Heat absorption mechanism, Covering effect, Dilution effect, Inhibiting effect, etc.
Red phosphorus flame retardant for hot melt adhesive has the following uses: Improve the flame retardant properties, processing performance and reduce cost of hot melt adhesives.
How Flame Retardants Make Plastics Do not Fear Open Flame? Let’s study the flame retardant mechanism together.
