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 Rollo de coextrusión de múltiples capas de alta barrera PP is air resistance, moisture resistance and processing performance change with the change of ethylene content. When the ethylene content increases, the gas barrier ofRollo de coextrusión de múltiples capas de alta barrera PP decreases, the moisture resistance of Rollo de coextrusión de múltiples capas de alta barrera PP improves, and the resin of Rollo de coextrusión de múltiples capas de alta barrera PP is easier to process.When the ethylene content is greater than 50 percent, the air resistance of Rollo de coextrusión de múltiples capas de alta barrera PP will be seriously damaged, so the ethylene content in EVOH generally remains between 20 percent and 45 percent.In addition, the air resistance of Rollo de coextrusión de múltiples capas de alta barrera PP 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.
