EVA Polyethylene Foam Seals
Utilizing EVA Polyethylene foam seals confers numerous advantages and finds extensive use in various industries and applications. This man-made material is thoughtfully designed to accommodate a wide range of requirements and is available in various grades, densities, and colors.
The raw materials being available in block form grant the flexibility to produce EVA seals, both small and large, from rolls or sheets in a cost-effective manner with minimal waste. EVA PE foam, characterized by its fine, closed-cell structure, excels in sealing and gasketing applications, effectively preventing the ingress and absorption of liquids, gases, and particles.
EVA PE foams are a popular choice for creating sealing and cushioning components that demand excellent recovery from repetitive impact and compression. These Polyethylene EVA foam seals offer additional attractive properties, such as resistance to wear and tear and a wide working temperature range spanning from -60°C to +90°C. They also exhibit excellent mechanical characteristics, including noise and vibration control, and serve as effective thermal insulation.
Moreover, EVA Polyethylene foams possess an aesthetically pleasing texture that's easy to fabricate, laminate, and craft into sealing components using a variety of techniques and processes. These EVA foam seals find applications in diverse industries like building and construction, HVAC, automotive, sports, and more, due to their versatility and performance attributes.

What are EVA Polyethylene Foam Seals?
EVA Polyethylene foam seals serve as essential components for joining surfaces, effectively acting as barriers to thwart the escape or intrusion of liquids, particles, or gases within applications. The term 'seal' encompasses a versatile range of products, including cut gaskets, strips, washers, extruded or molded profiles, and edge trims.
EVA, along with other polyethylene foams, is initially formed in block or 'bun' shapes, available in various densities and colors to cater to diverse application needs. EVA PE foam, a member of the Thermoplastic foam family, boasts a small, uniform, closed-cell structure, rendering it impermeable to liquids, gases, and particles, ensuring the creation of effective seals.
The cross-linking process establishes bonds between polymer chains, giving rise to a three-dimensional structure that bestows the material with enhanced compression strength, compression set, thermal stability, and tensile strength. EVA Polyethylene is manufactured similarly to standard PE foams, with the inclusion of the EV additive, imparting a distinctive 'rubbery/spongy' texture and improved material recovery, making it well-suited for demanding applications that require resilience and sealing efficacy.
Why use EVA Polyethylene Foam?
EVA foam seals, sourced from stocked material, serve diverse purposes such as filling gaps between uneven surfaces, reducing unwanted noise, vibrations, sealing against dust, gas, and liquids, and acting as cushioning or spacers. They come in various densities, colors, and can be cut from sheets or rolls or extruded and molded for specialized applications.
These EVA seals, known for their toughness and flexibility, possess a closed-cell structure, impervious to air and moisture. This ensures they neither absorb liquids nor permit their passage. EVA Polyethylene, being a soft, lightweight foam with a watertight, uniform cell structure, effectively seals against liquids, gases, and particles. It also exhibits resistance to wear and tear, Ozone, UV, and has a wide working temperature range from -60°C to +90°C. Furthermore, it offers outstanding mechanical characteristics for noise and vibration control and thermal insulation. While softer than some PE foams, EVA Polyethylene excels in resilience and durability, effectively absorbing impact and pressure without deterioration or tearing.
