Unveiling EVA Foam

What is EVA Foam?

Ethylene-vinyl acetate copolymer foam (EVA foam) is like the 'cotton candy' of the polymer world-made by polymerizing ethylene and vinyl acetate under high temperature and pressure, then injecting gas to create foam. This material inherently possesses three major characteristics:

• Light as a feather: With a density of only 0.03-0.3 g/cm³, it can easily float on water.
• Flexible and malleable: It maintains elasticity from -70℃ to 80℃, and can be bent at will without deformation.
• Safe and friendly: It burns without dripping or irritating odor, and passes common safety tests.
• EVA in your daily life: You may be in contact with this amazing material every day:
• Sports protection expert: EVA is used in the midsoles of running shoes and the core material of yoga mats to absorb impact.
• Packaging guardian: Custom-made padding in the transport cases of precision instruments. It can absorb the impact of a 10-meter drop.
• Creative DIY Material: Craft enthusiasts love using it for model making; it can be easily processed with scissors and carving knives.

Why Choose EVA?
Compared to traditional foam plastics, EVA is like an upgraded 'all-rounder':

• Balanced Performance: Its hardness ranges from 20-90 degrees (Shore C), making it suitable for both soft insoles and sturdy bag linings.
• Flexible Processing: It can handle hot pressing, engraving, screen printing, and other processes, and can be mixed with color masterbatch to create any color.
• Economical and Durable: It has outstanding anti-aging properties and maintains good elasticity even after 3-5 years of outdoor use.
