Low vinyl acetate (VA) content in EVA resins, typically ranging from about 7% to 15%, imparts certain properties that make these materials suitable for specific applications. Here are the main uses for low VA content EVA resins
Hot-Melt Adhesives
EVA resins with low VA content are widely used in hot-melt adhesives due to their good bonding strength and thermal stability. These adhesives are used in packaging, bookbinding, woodworking, and in the assembly of a variety of consumer products.
Packaging Films
EVA with low VA content is used in the production of packaging films because it improves the toughness and Sealability of polyethylene films. Such films are often utilized for agricultural, food, and industrial packaging.
Foam Products
Low VA EVA resins are used to produce various foam products, including mats and padding in sports equipment, due to their good resilience and durability.
Wire and Cable Insulation
The excellent electrical insulation properties and flexibility make low VA EVA resins suitable for use in coatings for wire and cable applications, particularly in low-temperature environments.
Footwear Components
While higher VA content is often preferred for softer, more flexible footwear components, low VA EVA can be used in applications requiring more rigidity and durability, such as in the soles of certain types of shoes.
Solar Panel Encapsulation
EVA resins with low to moderate VA content are used in encapsulating materials for solar panels, where they provide environmental protection and durability while maintaining high light transmission.
These applications take advantage of the stiffness, strength, and thermal stability that low VA content EVA resins provide, making them essential materials in various industrial sectors.
