EVA Plastic Pellets

Sipchem EVA 2518 CO is an 18% vinyl vinyl acetate copolymer resin. Designed for a variety of foam forming applications; Manufactured by IPC, a subsidiary of Sipchem in the Kingdom of Saudi Arabia, using ExxonMobil's high-pressure tube process.

When the content of vinyl acetate in EVA is less than 20%, it can be used as a plastic. EVA has good low temperature resistance, its thermal decomposition temperature is low, about 230 ° C, with the increase of molecular weight, the softening point of EVA rises, the machinability and surface gloss of plastic parts decline, but the strength increases, impact toughness and environmental stress cracking resistance improves,EVA chemical resistance, oil resistance compared with PE(polyethylene),PVC slightly worse, and with vinegar With the increase of ethylene acid content, the change is more obvious. EVA compared to PE performance improvement, mainly elasticity, flexibility, gloss, permeability and other aspects, in addition, its resistance to environmental stress cracking has been improved, the receptivity of the filler increases, can be used to add more reinforcement filler method to avoid or reduce EVA mechanical properties than PE decline. EVA can also be modified to get new applications, and its modification can be mainly considered from two aspects: it is to use EVA as the backbone of other monomer grafting; the second is to partially alcoholize EVA.

Mitsui Dow EVA has excellent aging resistance and chemical stability. Solar panels can be eroded by ultraviolet light, temperature difference changes and chemicals during long-term use, which can cause the performance degradation and failure of packaging materials. However, after special formulation adjustment and processing process treatment, Mitsui Dow EVA has excellent aging resistance and chemical stability, which can withstand the test of various harsh environmental conditions to ensure the long-term stable operation of solar panels.
