Overview
EPS-15-12 is a type of expandable polystyrene (EPS) characterized by its small bead size and uniform expansion properties. It is widely used in industries requiring lightweight, insulating, and cushioning materials. The material is produced through polymerization of styrene monomers and subsequent impregnation with a blowing agent, typically pentane. EPS-15-12 is favored for its versatility and cost-effectiveness. It can be molded into various shapes and densities, making it suitable for applications ranging from construction insulation to protective packaging. The material's closed-cell structure provides excellent thermal resistance and minimal water absorption.
Physical and Chemical Properties
EPS-15-12 appears as small, white or colorless beads before expansion. Upon heating, the beads expand up to 40-50 times their original volume, forming a lightweight foam with a density of 15-20 kg/m³. The material has a melting point of around 240°C and is insoluble in water but dissolves in organic solvents like acetone and toluene. Key chemical properties include its resistance to alkalis, acids, and alcohols, though it is susceptible to degradation by UV radiation and certain hydrocarbons. The closed-cell structure ensures low thermal conductivity (approximately 0.032-0.038 W/m·K), making it an effective insulator.
Main Applications
EPS-15-12 is extensively used in the construction industry for insulation panels, underfloor heating systems, and lightweight concrete substitutes. Its thermal insulation properties help reduce energy consumption in buildings. In packaging, EPS-15-12 protects fragile items during shipping due to its shock-absorbing qualities. It is also molded into disposable food containers, coolers, and agricultural seedling trays. The material's buoyancy makes it suitable for life jackets and floating docks.
Safety and Storage
EPS-15-12 is flammable and should be stored away from open flames, sparks, and high temperatures. Proper ventilation is necessary during handling to prevent the accumulation of pentane vapors, which are explosive at certain concentrations. Storage conditions should be cool (below 25°C) and dry to prevent premature expansion or degradation. Workers should use personal protective equipment (PPE) such as gloves and masks to avoid inhalation of dust during processing.
B2B Procurement Guide
When procuring EPS-15-12, buyers should specify bead size (typically 0.3-0.6 mm) and expansion ratio (commonly 40-50x). Verify the blowing agent content (usually 4-7% pentane) and ensure the material meets industry standards like ASTM C578 for insulation applications. Suppliers should provide certificates of analysis (CoA) for purity and consistency. Bulk purchases (e.g., by the ton) often yield cost savings, but consider logistics for storage and transportation due to the material's low density.
