Bio-based Sponge

Bio-based rubber foam, Bio-based thermoplastic foam

Nam Liong bio-based sponge materials are eco-conscious foam solutions developed for low-carbon product design and more sustainable supply chains. The series includes bio-based rubber foam and bio-based thermoplastic foam, using renewable, recycled, or lower-petroleum-dependence resources such as sugarcane, oyster shells and non-edible plant oils. Designed for wetsuits, water-sport apparel, footwear, bags, and protective gear, these materials help brands reduce reliance on conventional petrochemical foam while maintaining practical performance in hand feel, elasticity, lamination, cushioning, and end-product processing.


ā˜… Lower Petroleum Dependence: Incorporates renewable, recycled, or lower-petroleum feedstocks to help reduce fossil-resource reliance and support lower-carbon product development.

ā˜… Resource Circularity: Uses bio-shell powder to replace part of mineral powder, reducing mineral extraction demand while giving waste resources a second life.

ā˜… Sustainability Support: Nam Liong BIO-based rubber is FSCĀ® certified for environmental responsibility (License Code: FSCĀ® C181797).

With flexible formulation, thickness, density, hand feel, and post-processing options, Nam Liong bio-based sponge materials help customers balance sustainability claims, product performance, and scalable manufacturing.
