Ethylene-vinyl acetate (EVM) rubber exhibits relatively poor elasticity, restricting its wide application. The effects of flexible vulcanization agents, ethylene glycol dimethacrylate (EGDMA) and tripropanediol diacrylate (TPGDA), on the mechanical properties and vulcanization characteristics of EVM were studied.

Products with a vinyl acetate content of less than 40% are EVA resin; products with a vinyl acetate content of 40% to 70% are very flexible and possess elastic characteristics, primarily used as rubber elastomers and for polyvinyl chloride (PVC) modification. EVA resin within this content range is sometimes referred to as EVA rubber. Products with a vinyl acetate content in the range of 70% to 95%

3、EVM

EVM rubbers are produced by copolymerization of ethylene and vinyl acetate. Our ethylene-vinyl acetate copolymers are used as synthetic rubbers, or as modifiers in thermoplastics, specifically PVC. The main differences between the grades are the vinyl acetate content and the copolymer viscosity.

Thermoplastic elastomer (TPE) from ethylene vinyl acetate (EVA) and synthetic general purpose rubber, polybutadiene rubber (BR), which can improve set, wear, and tear properties of virgin EVA without any coloring problem, was developed.

5、Tough and Recyclable Ethylene–Vinyl Acetate Elastomers

Ethylene–vinyl acetate rubber (EVM) is a high-performance elastomer widely used across various sectors including electronics, communications, energy, and transportation. However, its relatively low mechanical strength restricts broader applications.

Ethylene vinyl acetate (EVA) and ethylene butyl acrylate (EBA)

Ethylene vinyl acetate copolymers (EVA) are thermoplastic polymers comprised of repeated units of ethylene and vinyl acetate. A more elastomeric product than polyethylene. It stands out for its excellent processability, flexibility and compatibility.

EVA (Ethylene-Vinyl Acetate) is a thermoplastic elastomer that bridges the gap between plastics and rubbers. Its unique balance of softness, flexibility, and resilience makes it an indispensable material across footwear, packaging, solar energy, healthcare, and automotive industries.

Ethylene Vinyl Acetate Elastomers (EVM) (ASTM Designation AEM)

Ethylene vinyl acetate elastomers belong to the class of specialty rubbers. The first patents on this copolymer were granted to ICI in 1938 [1]. But it took over 20 years until the polymerization process was optimized and the first products were commercially available [2].

Vinyl Acetate Elastomers (Vinyl Elastomers, VEs) are a class of thermoplastic elastomers synthesized from vinyl acetate monomers. These materials exhibit unique physical and chemical properties, enabling their widespread use in numerous industrial applications. The following article provides an overview of vinyl acetate elastomers:

Vinyl acetate elastomers (VEs) are critical polymeric materials distinguished by their exceptional properties, playing vital roles across various industries. This article introduces the fundamental concepts, classifications, applications, and future development trends of VEs.

1. Fundamental Concepts and Composition

Vinyl acetate elastomers are thermoplastic elastomers formed via free radical polymerization of vinyl acetate monomers. Their molecular structures contain abundant polar groups, such as carboxyl and ester groups, which confer excellent adhesion and flexibility. Additionally, VEs incorporate a rubber phase that enhances strength and wear resistance.

2. Classification

Based on application requirements and performance characteristics, VEs are categorized as follows:

1. General-Purpose VEs: High elasticity and flexibility, suitable for shoe soles, seals, etc.
2. Heat-Resistant VEs: Enhanced thermal stability for high-temperature components.
3. Oil-Resistant VEs: Superior oil resistance for hydraulic system seals.
4. Abrasion-Resistant VEs: High durability for heavy-load mechanical parts.

3. Applications

Due to their优异的性能 (excellent properties), VEs are widely used in:

1. Automotive Manufacturing: Tires, weatherstrips, shock absorbers.
2. Electronics and Electricals: Wiring insulation, switch contacts.
3. Construction Materials: Waterproof seals, door/window gaskets.
4. Sports Equipment: Athletic shoe soles, basketball hoops.
5. Others: Medical devices, aerospace, and aviation.

4. Future Development Trends

Advancements in technology will expand the applications of VEs. Key trends include:

1. High Performance: Improved mechanical and thermal properties for demanding applications.
2. Eco-Friendliness: Low-VOC formulations and recyclable products to reduce environmental impact.
3. Multifunctionality: Integration of self-healing, conductive, and other advanced functionalities.
