Eco-Friendly Neoprene Sponge, Limestone Based Rubber Sponge - Supplier

"Eco-Friendly Neoprene Sponge" is not produced by petroleum extraction products, but is a synthetic rubber produced by polymerization of acetylene gas produced by burning limestone. It has uniform microporous cells and can withstand stretching and bending for a longer period of time. Can reduce the consumption and dependence on oil.

The presence of hazardous substances such as polycyclic aromatic hydrocarbon compounds (PAHs) in synthetic rubber produced from petroleum refined products is inevitable. Synthetic rubber produced based on burning limestone has relatively low content of related harmful substances and the production process is more environmentally friendly. This is why it is also called eco-friendly neoprene sponge.

Currently, we can provide limestone neoprene sponges from Japan’s YAMAMOTO and Taiwan’s Nam Liong. Among them, Taiwan Nanliang's products comply with many international green directives and standards such as PAHs, REACH / SVHC, RoHS, CPSIA etc, and have passed Oeko-Tex® Standard 100 Class II certification, and can provide CR, SCR, SBR multiple models of products.
