The operating environment of the power module is relatively harsh. It is easy to burn at high temperature under overload conditions for a long time, which will burn the equipment and even cause fire and other accidents.
Insulating fireproof materials play an important role in the electrical industry, and can effectively block the scope of fire accidents. Among them, fireproof EVA sponge is not easy to ignite, and it can also play a role in heat dissipation when matched with fireproof PC sheets, effectively protecting the power module and preventing combustion.
Traditional EVA materials increase their ignition point by adding fire-retardant solvents or flame retardants. Fire-resistant EVA isn't completely inflammable; it's more appropriately called flame-retardant EVA. Similar to flame-retardant PC, another commonly used material in electrical equipment, flame-retardant EVA extinguishes quickly and leaves no residue, while maintaining its flexibility and insulation properties. In addition to being fire-resistant, it also offers high-temperature and weather resistance, excellent insulation, and is environmentally friendly and non-toxic, making it suitable for outdoor equipment and electronic device casings.
Fire rating standards
Based on the vertical burn test:
HB: Flammable, sustained flame;
V-2: Flame extinguishes within 30 seconds, with no burning debris falling;
V-1: Flame extinguishes even faster;
V-0: Extinguishes within 10 seconds, with no smoke produced.
The fire-resistant EVA material selected for power modules must balance flame retardancy, insulation, and mechanical strength. Lanxin insulation material corporation utilize a patented structural design to enhance ease of use and meet safety requirements in high-temperature environments. It is mainly used in transformers, motors, electronic equipment insulation wrapping, lithium battery packaging and other scenarios that require high temperature resistance and flame retardant protection. Lanxin has kinds types of fireproof materials and is an enterprise with many years of experience in the production of insulation materials.
