Ningbo Zhonggao Rubber & Plastic Manufacturing Co., Ltd. is one of the most reliable manufacturers and suppliers of eva foam rubber sealing strip in China. The company has world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale custom made eva foam rubber sealing strip from our factory.
Material Properties
Lightweight and high resilience
• EVA (ethylene-vinyl acetate copolymer) foam material has low density (0.08-0.3g/cm³);
• It weighs only 1/3 of traditional rubber;
• It also has excellent elastic recovery ability (rebound rate ≥ 90%);
• It is not easy to produce permanent deformation after long-term compression.
Low thermal conductivity and sound insulation
• Porous foam structure effectively blocks heat transfer;
• The thermal conductivity is as low as 0.03-0.05 W/m·K;
• Can reduce noise transmission;
• Suitable for door and window sealing, home appliance insulation and vehicle sound insulation system.
Wide temperature adaptability
• Maintains stable performance in the temperature range of -40℃ to +120℃;
• Resistant to cold and frost and does not soften at high temperatures;
• Suitable for outdoor equipment, northern buildings and high-temperature industrial environments.
Aging and chemical corrosion resistance
• The EVA material has a stable molecular structure;
• It is resistant to UV rays, ozone and weak acid and alkali corrosion;
• It can maintain sealing performance even when exposed to moisture or chemical media for a long time.
Environmental protection and easy processing
• Non-toxic and odorless, in compliance with RoHS and REACH environmental standards;
• Can be hot-pressed, cut or bonded;
• Suitable for complex cross-sections and large-scale production needs.
Tear and wear resistance
• The surface is specially reinforced, and the tear resistance is increased by 50%;
• The wear rate is low under dynamic friction environment;
• The service life is 1.5-2 times longer than that of traditional sealing strips.
