Overview
EPS2-80 is a type of expandable polystyrene (EPS) widely recognized for its versatility and cost-effectiveness in industrial applications. It consists of small, spherical beads that can be expanded and molded into various shapes, making it ideal for packaging, insulation, and construction purposes. EPS2-80 is favored for its lightweight nature and excellent thermal insulation properties. Its ability to absorb shocks and resist moisture further enhances its utility in protective packaging and building materials. The material is also recyclable, aligning with increasing environmental sustainability demands.
Physical and Chemical Properties
EPS2-80 exhibits a low density of approximately 20-30 kg/m³ when expanded, making it one of the lightest insulation materials available. Its closed-cell structure provides superior thermal insulation, with a thermal conductivity of around 0.033 W/m·K. The material is chemically inert, resistant to water, and unaffected by most acids, alkalis, and salts. However, it is soluble in organic solvents like acetone and toluene. EPS2-80 has a melting point of about 240°C and begins to decompose at higher temperatures, releasing styrene monomers.
Main Applications
EPS2-80 is extensively used in the packaging industry for protective cushioning of fragile items such as electronics, glassware, and medical equipment. Its shock-absorbing properties minimize damage during transit. In construction, EPS2-80 serves as an insulation material for walls, roofs, and floors, improving energy efficiency. It is also employed in disposable food containers due to its hygienic and lightweight properties. Additionally, EPS2-80 finds applications in arts and crafts, buoyancy aids, and geofoam for lightweight fill in civil engineering projects.
Safety and Storage
EPS2-80 is generally safe to handle but requires precautions to avoid health risks. Inhalation of dust during cutting or shaping should be minimized by using proper ventilation or protective masks. The material is flammable and must be stored away from open flames and heat sources. Storage conditions should be cool and dry to prevent premature expansion or degradation. Properly sealed containers are recommended to maintain bead integrity. In case of fire, EPS2-80 burns rapidly, producing toxic fumes, necessitating the use of appropriate fire suppression methods.
B2B Procurement Guide
When procuring EPS2-80, businesses should prioritize suppliers with certifications such as ISO or ASTM compliance to ensure quality. Key factors to evaluate include bead uniformity, expansion ratio, and residual pentane content, which affects expansion performance. Bulk purchases often yield cost savings, but storage capacity must be considered. Request samples to test expansion and molding characteristics before large-scale orders. Additionally, inquire about recycling or disposal options to align with corporate sustainability goals.
