在包裝應用領域，它可以與本身或其杜邦EVA樹脂的低溫熱封，也可用于復合瓶蓋襯墊;還可以制成吹塑、擠出、流延及共擠薄膜，或與其它樹脂混合使用。 EVA用途***，與阻燃劑配合，可以做成低煙無鹵或含鹵的阻燃料；選擇VA含量高的EVA做基料還可以做成耐油料；選擇熔融指數適中的EVA，加入2～3倍于EVA的填充阻燃劑可以制得擠出工藝性能和價格較均衡的隔氧層

Elvax? 3130

Ethylene Vinyl Acetate Copolymer

DuPont Packaging & Industrial Polymers

產品說明：

DuPont? Elvax? 3130 is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.

Composition

• 12 % By Weight Vinyl Acetate comonomer content

• Thermal Stabilizer: BHT antioxidant

Applications

• This resin is designed to provide a low temperature heat seal to itself or many other materials commonly used in flexible packaging applications. The melt properties of this resin allow it to be processed on blown film equipment over a wide range of film thickness and blow-up ratios. It can also be co-extruded with a variety of other polymers. This resin is typically used as low temperature seal layer in co-extruded films.
