How Does VAPP R Foam's Impact Absorption Compare to Standard EVA Foams for Sports Protection?
VAPP R Foam significantly outperforms standard EVA materials with its superior compression deflection (up to 25.0 lb/in²) and exceptional tensile strength (up to 350 lb/in²), delivering up to 40% better impact force reduction. This translates to thinner, more effective protective components in helmets, pads, and guards while maintaining flexibility. Our testing shows VAPP R Foam maintains its protective properties even after repeated impacts, making it ideal for high-performance sports protection where safety and comfort are paramount. Request our comparative testing data to see how VAPP R Foam can enhance your protection equipment.
Manufactured to exacting specifications with over 31 years of expertise, our VAPP R Foam boasts impressive tensile strength (up to 350 lb/in²) and elongation properties (300-380%) that ensure durability and consistent performance throughout product lifecycles. The low compression set (max 10%) guarantees long-term resilience even after repeated impact exposure, while the controlled density range provides options for different application requirements - from lighter R-12S (0.12-0.15 g/cm³) to the more robust R-24S (0.24-0.30 g/cm³). Each variant is ASTM-certified and available in standard sheet sizes, making VAPP R Foam the material of choice for manufacturers demanding reliable protection with precise performance characteristics.
