Prod
EVOH is a high-performance copolymer of ethylene and vinyl alcohol, renowned for its exceptional gas barrier properties, especially against oxygen, nitrogen, and carbon dioxide. It also exhibits outstanding oil resistance, solvent resistance, and mechanical strength, while being non-toxic, odorless, and environmentally friendly.
Key Features
- Excellent oxygen and aroma barrier performance
- Good oil and organic solvent resistance
- High mechanical strength and toughness
- Low moisture permeability under dry conditions
- Good processability and heat-sealing properties
- Non-toxic and compliant with food contact standards
Main Applications
- Food packaging: flexible films for meat, dairy, beverages, and frozen food
- Automotive: fuel tanks and fuel system tubing
- Pharmaceutical packaging: blister packs and sterile barrier films
- Industrial: multilayer pipes, chemical containers, and protective coatings
Typical Grades
EVOH grades are classified by ethylene content, usually ranging from 27% to 48%. Lower ethylene content provides higher barrier properties, while higher ethylene content improves moisture resistance and flexibility.
