EXPANDED POLYSTERENE (EPS)
EPS Granules Supplier – Lightweight, Insulating & Sustainable Material
Expanded Polystyrene (EPS) is a lightweight, rigid, and highly versatile plastic material made up of 98% air and 2% polystyrene. Through an innovative expansion process, small polystyrene beads containing pentane gas are exposed to steam, causing them to expand to approximately 40 times their original volume and create a structure of individual closed cells. This unique manufacturing process results in a material that is remarkably lightweight while maintaining excellent thermal insulation properties. EPS’s closed-cell structure creates trapped air pockets that significantly reduce heat transfer, making it an ideal choice for building insulation, protective packaging, and food service applications. The material’s versatility is enhanced by its moldability, allowing manufacturers to create custom shapes and sizes through a secondary heat treatment process using specific molds.
At Neelgiri Polyplast, a leading EPS granules supplier in India, we provide high-quality Expanded Polystyrene raw material that meets industrial standards for durability, safety, and performance. Known for its excellent insulation properties, strength-to-weight ratio, and recyclability, EPS has become an essential choice in industries such as construction, packaging, cold chain logistics, and consumer products.
Why Choose EPS Material?
EPS exhibits outstanding moisture resistance due to its closed-cell structure, preventing water absorption and maintaining its insulative properties even in damp conditions. The material’s compression strength and dimensional stability make it particularly suitable for construction applications, where it serves as both insulation and a lightweight structural element. Additionally, EPS’s shock-absorbing capabilities make it an excellent choice for protective packaging of sensitive equipment and products. Despite its advantages, EPS does have some limitations, including limited chemical resistance and susceptibility to UV degradation when exposed to direct sunlight for extended periods. Environmental concerns have also been raised regarding its biodegradability, though EPS is 100% recyclable when properly collected and processed.
