Features Of High Barrier PP Multi-layer Co-extrusion Sheet Roll

EVOH is highly crystalline, and its properties mainly depend on the mole fraction of two kinds of comonomers.
The EVOH of Gulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi is air resistance, moisture resistance and processing performance change with the change of ethylene content. When the ethylene content increases, the gas barrier ofGulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi decreases, the moisture resistance of Gulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi improves, and the resin of Gulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi is easier to process.When the ethylene content is greater than 50 percent, the air resistance of Gulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi will be seriously damaged, so the ethylene content in EVOH generally remains between 20 percent and 45 percent.In addition, the air resistance of Gulungan Lembar Co-ekstrusi Multi-lapis PP Penghalang Tinggi decreases with increasing temperature, such as from 20℃.At 35℃, the oxygen transmittance increases more than three times.In addition, EVOH also has high strength, elasticity, surface hardness and wear resistance.

Specification of High Barrier PP Multi-layer Co-extrusion Sheet Roll
 
EVOH (also known as EVAL) is a random copolymer of ethylene – vinyl alcohol.
It is a crystalline polymer with a chain molecular structure.The melt mass flow rate was 0.7 ~ 20 g / 10min, the density was 1.13 ~ 1.21 g/cm, the melting point was 158 ~ 189℃, and the tensile fracture strength was 44 MPa.The content of ethylene (mole fraction, the same below) in EVOH is usually 20% ~ 45%, and that of ethylene alcohol is 55% ~ 80%.EVOH and polyvinylidene chloride (PVDC) and polyamide (PA) and known as the world’s three barrier resin.
