What is compression molded eva foam?

Compression molded EVA (Ethylene Vinyl Acetate) foam is a manufacturing process used to create lightweight, durable, and shock-absorbing foam products. The process involves heating EVA foam sheets or pellets and pressing them into a mold under high pressure and temperature. This allows the material to take on precise shapes and maintain consistent density and texture.

Key Features of Compression Molded EVA Foam:

Lightweight & Durable – Ideal for applications requiring strength without excessive weight.

Shock Absorption – Commonly used in sports equipment, footwear, and protective gear.

Water & Chemical Resistance – Suitable for outdoor and industrial applications.

Customizable Shapes & Textures – The molding process allows for detailed designs, logos, and functional patterns.

Common Applications:

Footwear – Midsoles, insoles, and outsoles for running shoes and sandals.

Protective Gear – Helmets, knee pads, and impact-absorbing padding.

Cushions and seat- kayak Seat Cushions, kayak seat pad and backrest

Medical & Orthopedic Products – Custom orthotics and prosthetics.

Automotive & Industrial Uses – Vibration dampening components and tool case inserts.

Consumer Products – Yoga mats, seat cushions, and custom packaging.
