Round EVA

Updated: 2026-08-06

Overview

EVA foam sheet, or Ethylene-Vinyl Acetate foam, is a copolymer material known for its flexibility, durability, and lightweight properties. It is commonly produced in circular or sheet forms for industrial and consumer applications. The material's closed-cell structure makes it resistant to moisture, chemicals, and UV radiation, ensuring longevity in diverse environments. EVA foam is favored for its ease of customization, as it can be cut, molded, or laminated to meet specific requirements. Its versatility extends to industries such as packaging, automotive, sports, and construction, where cushioning, insulation, or protective properties are essential.

Physical and Chemical Properties

EVA foam exhibits a density range of 0.03-0.20 g/cm³, making it lightweight yet sturdy. Its melting point falls between 70-90°C, limiting its use in high-temperature environments. The material is insoluble in water and resistant to most chemicals, including oils and weak acids, which enhances its suitability for industrial applications. Key mechanical properties include excellent shock absorption and vibration damping, attributed to its elastic and compressible nature. EVA foam also provides thermal insulation, reducing heat transfer in applications like flooring or protective gear. Its closed-cell structure prevents water absorption, ensuring dimensional stability even in humid conditions.

Main Applications

In packaging, EVA foam sheets are used for protective inserts, cushioning delicate electronics or medical equipment. The sports industry leverages its shock-absorbing qualities for yoga mats, gym flooring, and helmet liners. Footwear manufacturers incorporate EVA foam into midsoles for comfort and energy return. The material is also popular in DIY and crafting due to its ease of cutting and shaping. Industrial applications include gaskets, seals, and insulation panels, where its chemical resistance and durability are critical. Additionally, EVA foam is used in marine and automotive sectors for flotation devices and noise reduction components.

Safety and Storage

EVA foam is generally non-toxic and safe for handling, but precautions should be taken during cutting or sanding to avoid inhaling dust particles. Proper ventilation is recommended when processing the material. Storage conditions should prioritize cool, dry environments to prevent deformation or degradation. Avoid prolonged exposure to direct sunlight or temperatures above 90°C, as this may cause the foam to soften or lose structural integrity. Fire-retardant variants are available for applications requiring enhanced safety measures. Always check manufacturer guidelines for specific storage and handling recommendations.

B2B Procurement Guide

When sourcing EVA foam sheets, prioritize suppliers with certifications like REACH or RoHS to ensure compliance with environmental and safety standards. Key specifications to verify include thickness (commonly 1-50 mm), density, and color options. Custom die-cutting or laminating services may be available for bulk orders. Prices vary based on material grade and order volume, with discounts often applicable for large-scale procurement. Lead times and MOQs (Minimum Order Quantities) should be clarified upfront. For specialized applications, request samples to test performance under real-world conditions before committing to a purchase.
