Hangzhou Epsole Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of expanded polystyrene eps in China. We warmly welcome you to buy high quality expanded polystyrene eps for sale here from our factory. Good service and reasonable price are available.
Products Description

We offer EPS materials with a wide density range from 12 kg/m³ to 35 kg/m³ to meet diverse application needs. For example, our standard packaging grade EPS (density 18-20 kg/m³) provides a compressive strength of ≥100 kPa (according to ASTM D1621 standard), ensuring effective protection of goods during stacking and transportation. For building insulation applications, our insulation grade EPS (density 25-30 kg/m³) features an excellent thermal conductivity as low as 0.033-0.036 W/(m·K) (according to ISO 8301 standard), significantly improving energy efficiency.
We understand the importance of batch consistency to your production. Through our self-developed, fully automatic, closed-loop controlled pre-expansion machine and a stable curing process lasting up to 48 hours, we ensure uniform particle size distribution of the pre-expanded beads and density fluctuations controlled within ±0.5 g/L. This means that when you use our EPS raw materials for molding, you will achieve more stable product dimensions and performance, reducing the scrap rate.


Packaging sector: "For shock-resistant packaging of precision instruments and electronic products, we recommend models with high elasticity and cushioning properties; for cold chain logistics, we offer flame-retardant and low-water absorption models."
Construction sector: "Our EPS boards for external thermal insulation composite systems (ETICS) meet relevant building fire safety requirements (such as B1 class) and possess excellent dimensional stability and aging resistance."
Other sectors: "Suitable for special needs such as fishing buoys, model making, and underfloor heating insulation layers, we provide technical consulting and customized formulations."
Our Advantages
With nearly 20 years of experience in the research, development, and manufacturing of EPS machinery and equipment, Hangzhou Epsole possesses a profound understanding of EPS materials. Our complete production line technology, from pre-expansion and molding to recycling, ensures we have ultimate control over every parameter in the material production process.
We have several fully automated continuous pre-foaming production lines, each with a daily capacity of up to XX tons. The production lines are equipped with Siemens/Mitsubishi PLC control systems and online density monitors, achieving complete automation and data visualization from raw material feeding to finished product packaging. This minimizes human error and guarantees absolute product consistency.
As a large-scale manufacturer, we support flexible orders ranging from one container to a full shipload. Standard products have stable delivery times. We use industrial packaging consisting of a moisture-proof film liner and high-strength PP woven bags, or provide pallet packaging according to your requirements, ensuring the product remains dry and intact even after long-distance sea transport.
