EVOH

EVASIN EVOH Resin/EVOH Granules/EVOH Ethylene Vinyl Alcohol Copolymer CAS:26221-27-5/EVOH Supplier

Chang Chun Petrochemical Co.,Ltd is a famous comprehensive chemical industry group in Taiwan, and it is also the first enterprise in the world to realize the industrialized production of poval resin .

Combining the processability of ethylene polymer with the barrier effect of vinyl alcohol polymer, ethylene vinyl alcohol copolymer not only shows excellent processability, but also shows excellent blocking effect on gas, odor, perfume and solvent. Due to its thermal stability combined with ethylene, the multilayer container containing EVOH barrier layer can be completely reused. EVOH has always been the most widely used high barrier material. In addition to the non stretching type, the film type of this material also includes biaxial stretching type, aluminum evaporation type, adhesive coating type, etc. among the biaxial stretching type, there are heat-resistant types for aseptic packaging products.

Specification:

    

• Chemical properties

The most remarkable feature of EVOH resin is its barrier effect on gas. It is used in the packaging structure to improve the retention of flavor and quality by preventing the infiltration of oxygen.In the use of inflatable packaging technology, EVOH resin effectively retains carbon dioxide or nitrogen used to protect products.

• Oil resistance

EVOH resin also has strong oil resistance and organic solvent resistance. After immersion in various solvents and oils at 68 ° f for 1 year, the weight increase percentage is 0% for solvents such as p-cyclohexane, xylene, petroleum ether, benzene and acetone, 2.3% for ethylene glycol and 12.5% for methanol 2%, 0.5% for salad oil 1%.

• Mechanical properties

EVOH resin has high mechanical strength, elasticity, surface hardness, wear resistance, weather resistance, and strong antistatic property. EVOH film has high gloss and low haze, so it is highly transparent.

• Thermal properties

EVOH resin is the resin with the highest thermal stability among all commercial strong barrier resins. This property enables the waste generated in processing to be regenerated and reused. The recycled material contains more than 20% EVOH.

Application:

EVOH high gas barrier functional resin can isolate oxygen to prevent the deterioration of content items. Therefore, EVOH is widely used in mayonnaise, ketchup and other food packaging materials. In addition, this product is also used in plastic fuel tank, which plays a positive role in preventing the leakage of volatile gasoline and reducing the weight of the vehicle. In the construction field, it is used to replace metal floor heating pipes, and the demand is gradually expanding in areas other than food packaging.

Packaging & Shipping:

The resin is packaged in internally film-coated polypropylene woven bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fifire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flflammable substance is strictly prohibited.
