Everything You Need to Know About EVA for Rubber & Plastics Applications
EVA (Ethylene-Vinyl Acetate) is a versatile copolymer widely used in rubber and plastic manufacturing. Its unique properties make it ideal for various applications, from footwear to packaging. This guide covers everything buyers need to know about EVA, including types, features, and sourcing tips.
How to Find Reliable EVA from China in 2025
China remains a top supplier of EVA due to its competitive pricing and advanced production capabilities. To find reliable suppliers:
- Check certifications like ISO 9001 and REACH compliance
- Review customer feedback on platforms like Alibaba
- Request samples to test material quality
- Verify production capacity and lead times
Top Chinese manufacturers often offer customized EVA solutions with VA content ranging from 5% to 40%.
What Buyers Should Know Before Buying EVA from China
When importing EVA from China, consider:
- VA content affects flexibility and transparency
- Minimum order quantities (typically 1-5 tons)
- Shipping costs and import duties
- Payment terms (30% deposit is common)
Always request a Certificate of Analysis to verify material specifications.
Types of EVA
There are three main EVA classifications:
- Low VA Content (5-15%): Rigid, used for pipes and industrial applications
- Medium VA Content (15-30%): Balanced properties for footwear and sports equipment
- High VA Content (30-40%): Extremely flexible, ideal for adhesives and foam products
Functions and features of EVA
EVA offers unique advantages:
- Excellent shock absorption
- UV and weather resistance
- Good clarity and gloss
- Low-temperature flexibility
- Chemical resistance
These properties make it superior to many traditional rubber and plastic materials.
Scenarios of EVA
Common applications include:
- Footwear soles and sandals
- Sports equipment padding
- Packaging films
- Hot melt adhesives
- Solar panel encapsulation
- Foam mats and toys
The medical industry also uses EVA for tubing and drug delivery systems.
How to Choose EVA
Selecting the right EVA depends on:
- Application requirements: Consider stress, temperature, and environmental factors
- VA content: Higher VA means more flexibility
- Additives: UV stabilizers or flame retardants may be needed
- Processing method: Injection molding requires different grades than extrusion
