Introduction of various types of pp flame retardant materials fireproof plastic materials
Polypropylene (PP) has become the most versatile general-purpose polymer material in modern life due to its excellent physical and chemical properties. However, the flammability of PP limits its application in many fields. In recent years, environmental protection and safety of materials have become the focus of attention, so the development of environmentally friendly flame retardant PP has been a research hotspot.
Flame retardant pp materials can be classified into halogen-containing flame retardant and halogen-free flame retardants according to whether they contain halogen-containing flame retardants.
The halogen-free flame retardant PP material can be further divided into an expanded flame retardant pp sheet, a phosphorus flame retardant pp sheet, a metal hydroxide flame retardant pp sheet, and a bio-based flame retardant pp sheet.
Since the flame retardant efficiency of each flame retardant is different, it is necessary to add different doses of the flame retardant to achieve the same flame retardant effect. The addition of a large amount of flame retardant will cause damage to the mechanical properties of pp, especially toughness, and therefore a suitable flame retardant according to the practical use of the pp material is required.
Wenzhou Xintai New Materials stock Co., Ltd. develops and produces various types of flame retardant PP sheets to meet the requirements of PP sheets in various environments.
Flammability UL94 rating is the most widely used flammability performance standard for plastic materials. It is used to evaluate the ability of a material to extinguish after it has been ignited. The flame retardant grade of plastic is gradually increased from HB, V-2, V-1 to V-0.
Generally, the flame retardant grade of plastic reaches UL-94V-2 to meet the requirements of general plastic fire protection applications.
