It is a kind of very good packing lining material worthy of recommendation. Flame retardant EVA lining made of flame retardant EVA material is very popular with flammable and explosive industry. When EVA lining is processed, the fire resistance of EVA materials should be tested to ensure the fireproof performance of EVA products. How should this be tested? It's really very simple.
1. in the EVA foaming process, proper amount of EVA flame retardant masterbatch will be added to ensure that the fire resistance of EVA material will not be affected.
2. commonly used fireproof EVA foam test: the EVA product is burned with alcohol lamp for 10-15 seconds, and within 8 seconds after leaving the fire, the fire will be extinguished, and the EVA lining is intact.
The 3.EVA lining can be used freely at very high temperature, so it can also increase the fire temperature. If there is no combustion phenomenon, it is also qualified.
