2]/day, this film delivers a barrier performance at the level of metallized polyester (PET) and typically higher than most other clear barrier solutions such as polyvinylidene chloride (PVdC) or ethylene vinyl alcohol copolymer (EVOH) coated or coextruded films," the company adds.
27 million) in boosting the production of its EVAL ethylene vinyl alcohol copolymer (EVOH resin) in Kuraray America Inc.
A first layer of an ethylene vinyl alcohol copolymer has first and second sides.
Some excellent tanks have been made of coextruded six-layer structures that include two layers of high-density polyethylene enclosing an ethylene vinyl alcohol copolymer barrier-layer and a layer of treated, recycled, or regrind plastic material.
will be located in Miyazaki and will manufacture and distribute hollow fiber membranes using EVAL, Kuraray's proprietary ethylene vinyl alcohol copolymer (EVOH resin).
The company is investigating a variety of raw materials, including polypropylene and polyester, but also polyvinyl alcohol, ethylene vinyl alcohol copolymers and liquid crystal polymers.
Materials include, but are not limited to, polyethylene terephthalate, polypropylene, and barrier polymers (such as ethylene vinyl alcohol copolymer and nylon).
This it accomplishes by: offering a wider operating window for contaminants such as ethylene vinyl alcohol copolymer (EVOH), moisture, and zinc stearate lubricants--thus allowing for a higher mix in recycle streams (in turn, reducing the environmental footprint of landfills); improving impact strength for wet blends (700 ppm water) and blends with lubricant; and reducing die buildup on manufacturing equipment as it helps to incorporate polar components into the polymer matrix--resulting in greater processing efficiency.
