Import Expandable Polystyrene — Buy in Bulk from Supplier in Taiwan

Expandable polystyrene from Cleanmate Tech Ltd. is a pre-expanded bead material composed of 100% polystyrene with pentane as the blowing agent, designed for insulation and packaging applications. The supplier specifies a density range of 8 to 30 kg/m³ and a thermal conductivity of 0.035 W/m·K, consistent with standard EPS grades used in construction and cold chain logistics. The material is chemically inert and resistant to water absorption, making it suitable for humid environments.

The product is available in customizable shapes and sizes, indicating post-expansion processing capabilities. Standard EPS grades are classified by density and expansion ratio, with lower densities (8-12 kg/m³) used for packaging and higher densities (20-30 kg/m³) for structural insulation panels. No additives or flame retardants are mentioned, so the material is likely unmodified, standard EPS. The supplier does not specify the type of pentane used or residual monomer levels.

Buyers in packaging, refrigerated transport, and building insulation sectors use this material for cushioning, thermal barriers, and lightweight core panels. It is typically supplied in bulk bags or palletized blocks. No minimum order quantity is confirmed, and lead time is not stated. Buyers must request confirmation of packaging type, shipping terms, and whether the product complies with regional safety standards such as REACH or RoHS.
