The intrinsic relationship between the surface hardness and wear resistance of handle toy foam tube is the result of the combined effects of material structure, process, and environmental factors.
With each silent flow of air, it ensures that the technological care delivered reaches every inch of the leg with precision, stability, and gentleness.
The compression set rate of handle toy foam tubes must be controlled throughout the entire process of material research and development, production and manufacturing, and quality inspection.
NBR foam tube's unique internal structure plays a key role in suppressing convection, reducing thermal conductivity, resisting moisture and humidity.
Among various foam materials, EVA (ethylene-vinyl acetate copolymer) foam, due to its excellent fatigue resistance, has become the preferred material for demanding dynamic applications.
EVA foam can indeed experience significant aging in extreme temperature environments, particularly under high temperatures and strong UV radiation, resulting in softening, discoloration, cracking, and performance degradation.
