Ethylene Vinyl Acetate (EVA) Tapes
-- Steady & Reliable Manufacturer --
Technical Overview
Ethylene Vinyl Acetate (EVA) foam tapes are highly versatile, closed-cell products known for their superior flexibility, low temperature performance, and ease of conversion. The proportion of vinyl acetate (VA) content directly influences the material's softness, flexibility, and tackiness (when used as an adhesive base). As a foam tape, EVA provides excellent cushioning, shock absorption, and moderate sealing capabilities against air and moisture.
EVA's high resilience and resistance to stress cracking make it a preferred choice for protection and gap filling in consumer goods. Key parameters include Shore C hardness, specific gravity, and flexibility at sub-zero temperatures. The closed-cell structure ensures a minimal water absorption rate, suitable for light sealing applications.
Why Choose Us
Differentiating Attributes
- Exceptional Flexibility at Low Temperatures: Unlike many polymers, EVA maintains its cushioning and sealing properties even when exposed to temperatures significantly below freezing, making it critical for cold-weather applications.
- High Resilience and Shock Absorption: The material quickly recovers its shape after compression, providing durable cushioning and effectively mitigating impacts and mechanical shock.
- Ease of Die-Cutting and Processing: The uniformity and soft texture of EVA allow for extremely clean and precise die-cutting into intricate, custom shapes with minimal tool wear.
- Non-Toxic and Odorless: Suitable for use in applications involving consumer contact, food processing equipment, and confined electronic spaces.
- Good Resistance to Chemicals: Shows resistance to many common solvents, acids, and bases encountered in cleaning and industrial environments.
- Cost-Effective Cushioning: Provides superior performance to standard PE foams while remaining a highly economical solution for high-volume protection and mounting tasks.
Core Features
Applications
- Packaging and Component Protection: Used as internal padding and separators in retail packaging to cushion sensitive products during shipping.
- Low-Temperature Sealing: Gasketing and sealing components in cold chain equipment, refrigerated showcases, and appliances due to flexibility at sub-zero temperatures.
- Foot Pads and Anti-Slip Bases: Die-cut into specific shapes for use as non-skid feet on small appliances and consumer electronics.
- Sports and Recreational Equipment Padding: Providing soft, resilient cushioning in handles, protective gear, and footwear components.
- Vibration Damping in Electronics: Securing batteries or displays while absorbing operational vibrations within portable devices.

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: How does the VA (Vinyl Acetate) content affect EVA foam?
- A: Higher VA content results in a softer, more flexible foam with better resilience, lower melting temperature, and improved low-temperature performance. Lower VA content makes the foam harder and more rigid.
- Q: Is EVA foam considered waterproof?
- A: As a closed-cell foam, it resists water penetration and has a low water absorption rate. It functions as an effective environmental seal against splashes and dust, but its ultimate sealing capability depends on the compression level and adhesive type.
- Q: Can EVA be laminated with other materials?
- A: Yes, EVA is commonly laminated with films, fabrics, or other types of foam to create composite materials with enhanced properties like wear resistance or UV protection.
- Q: What is the maximum continuous service temperature for EVA?
- A: Most EVA formulations are limited to a continuous service temperature around 70°C to 80°C before permanent compression set or softening may occur.
