Packaging sponge lining is a kind of foam material, which has the advantages of excellent cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, and is non-toxic, odorless and non absorbent. It has fine structure, smooth surface, soft and elastic handle, excellent shock proof, moisture-proof, anti-skid and anti-wear functions. It can effectively protect the goods from damage, impact and vibration, and does not contain pollution, chemistry and denaturalization plasticity. The product has passed UL certification and reached the V0 level with outstanding electrical functions.
Flame retardant principle of packing sponge lining:
1. In the solid phase, the chemical differentiation mode is changed to reduce the generation of fuel.
2. In the gas phase, the combustion free radicals are eliminated and the oxidation fraction of fuel is reduced.
3. Dilution + cooling + heat insulation and oxygen isolation, releasing inert gas and carbon formation during incineration.
In the inner lining of packing sponge, the burning method with modified information is used to prevent or delay the ignition, slow down the burning rate and flame transmission, and reduce the amount of smoke (reduce the burning rate, reduce the release of toxic gas = 1 / 3 of the non flame retardant materials).
