XLPE (crosslinked polyethylene) and XLEVA (crosslinked ethylene-vinyl acetate) are two of the most versatile, high-performance foams available. But how do they compare?
XLPE Foam
PE foam—especially its cross-linked version (XLPE)—is a lightweight, flexible, and durable material. Crosslinking boosts its chemical resistance, thermal insulation, and elasticity, making it bounce back easily after compression. While it lacks the glossy finish of EVA, it’s odorless, eco-friendlier, and firmer with better heat resistance.
Key Features:
- Lightweight and flexible
- Shock- and water-resistant
- Thermal and sound insulation
- Odorless and weatherproof
- Rebounds quickly
XLEVA Foam
EVA foam is known for its rubber-like softness, elasticity, and smooth, shiny surface. It’s waterproof, UV-resistant, and tough even in low temperatures. EVA is available in many colors and densities, but it is known to have a vinegar-like smell.
Advantages:
- Soft, elastic, and flexible
- Glossy finish
- Durable in extreme temps
- Easily cleaned and cut
- Strong UV resistance
Similar Uses, Slightly Different Strengths
Both foams are widely used in industries like automotive, sports, construction, packaging, and healthcare. XLEVA is more commonly used in sports and automotive products, while XLPE excels in insulation and structural uses.
Common Applications:
- Automotive parts
- Footwear and sports gear
- Building and pipe insulation
- Packaging and electronics
- Healthcare and artificial grass underlays
Bottom Line:
Choose PE for firmer, eco-friendly insulation and structure. Go with EVA when you need softness, flexibility, and easy customization.
