EVA foam is the acronym for the closed-cell ethylene-vinyl acetate copolymer foam used as an effective substitute for a variety of materials. Compared to PE foam, EVA foam provides good gloss and clarity, remains strong at low-temperatures, retains its resistance to UV radiation and stress-cracking, and possesses hot-melt adhesive waterproof properties.
EVA foam has a fine uniform cell structure that allows it to be processed much like other thermoplastics. It retains its flexibility and resilience, quickly recovers from compressions, and absorbs colors. The foam is typically formed in a mold which becomes a sheet of closed-cell foam (“a bun”). Bun dimensions vary depending on the density of the foam. The bun is cut into sheets or fabricated into a specific shape or item per specification.
EVA is expanded or foam rubber, which is used for sports equipment padding. Snow and water ski boots, bicycle saddles, hockey pads, boxing gloves and helmets, and fishing rods and reels are constructed with EVA.
Benefits gained from using the EVA for road cases interior includes:
• vibration and impact absorptions,
• weather and chemical, oil, and fuel spill/splash resistances,
• thermal insulation and acoustical properties
These high-density EVA sheets come in size of 1.5X3M for 5,10 and 15mm thickness, and 1.22×2.44M for 20mm and above.
