Product Description

Product Description

EVOH

EVOH (Ethylene Vinyl Alcohol Copolymer) is a high performance barrier plastic material. It is mainly prepared by copolymerization of two monomers, ethylene and vinyl alcohol. EVOH has excellent gas blocking performance, especially for oxygen, carbon dioxide and water vapor blocking performance is very good, so it is widely used in food packaging, medical packaging, cosmetic packaging and other fields.

Application

EVOH particles can be used to make plastic films or containers with an EVOH barrier layer. These materials can effectively prevent the penetration of oxygen and other gases, thereby extending the shelf life of food and maintaining its freshness. Besides food packaging, EVOH particles are also used for packaging solvents, cosmetics, medicines, toothpaste tubes, and electronic products, etc. The high barrier property of EVOH particles makes it an ideal material for manufacturing plastic fuel tanks, which can prevent fuel leakage and evaporation. EVOH particles can be used to make oxygen-blocking plastic pipes, which have excellent weather resistance and gas-blocking properties and are suitable for direct drinking water systems, heating systems, and other fields. Medical materials: In the medical field, EVOH demonstrates dual charm: it has the purity similar to glass and the flexibility of plastic. It is used in dialysis bags to precisely control substance exchange, and the inner layer of medicine bottles relies on it to protect expensive drugs. What is particularly special is that some high-end contact lenses use EVOH composite materials, making the lenses both breathable and moisturizing. EVOH particles are also applied in areas such as the anti-permeation layer of car fuel tanks and protective components of photovoltaic modules. In the 3D printing field, filaments with EVOH added can produce objects with both strength and precision.
