Rubber Sponge

Rubber Sponge

Answering the needs of the industry.


Synthetic or natural rubber are mixed with a foaming agent and other components and heated to produce rubber sponge. Due to its light weight and toughness, rubber sponge is widely used for automotive, office equipment, public works and construction, packaging, sports other advanced applications.


Lightweight and Durable.
Lightweight, with high tear and other physical strengths.

Thermal insulation
With low thermal conductivity, it is an excellent heat retention material.

Low water absorption
The closed cell structure prevents water absorption.

Shock Absorption
With optimum shock absorbing property, it serves as a great buffer material.

Excellent weatherability. EPDM-based and NBR-based sponges show no failures after a 72 hour ozone resistance test (50pphm×38°C 20% elongation)

Low Combustion
Certified Flame retardant test such as UL94 HF-1 for CR based sponge and UL94 HBF for EPDM based sponge(E-4382,E-4338 and F4238)
