EPS HS 221, produced by Tabriz Petrochemical Company, is a standout medium-density expandable polystyrene (EPS) known for its exceptional properties and versatility in applications where fire retardancy is not required. This guide provides a comprehensive look at EPS HS 221, exploring its manufacturing process, applications, and why it’s a top choice for both insulation and packaging solutions.
 
What is EPS HS 221? EPS HS 221 belongs to the TPC Performance range of expandable polystyrene products. It comprises spherical polystyrene beads with pentane as the expansion agent, designed to achieve low- and medium-density foam blocks. This EPS grade is particularly noted for its high strength, which ensures that the foam does not develop lumps during pre-expansion.
 
Key Features of EPS HS 221
Manufactured by Continuous Mass Polymerization: This method guarantees uniform properties and superior quality across batches.
Medium Density: Typically around 22 kg/m³, making it ideal for a variety of applications.
Non-Fire Retardant: Suitable for applications where fire retardancy is not a criterion.
High Strength Formulation: Ensures smooth pre-expansion, crucial for maintaining quality in finished products.
 
Applications of EPS HS 221 EPS HS 221 is extremely versatile, used predominantly in:
Packaging Solutions: Ideal for creating protective packaging that requires cushioning properties.
Construction Insulation: Used as thermal insulation boards in construction applications where enhanced insulation is needed without the requirement for fire resistance.
General Foam Products: Suitable for numerous foam product applications due to its flexibility and ease of molding.
 
Packaging and Storage Tips
Packaging: EPS HS 221 is supplied in octabins on wooden pallets, with each octabin containing 1000 kg of material, ensuring efficient handling and storage.
Storage Recommendations: To preserve its quality, EPS HS 221 should be stored indoors at temperatures below 20°C and processed within one month of delivery.
 
Processing Guidelines
Pre-expansion: Achievable at densities around 22 kg/m³ with state-of-the-art preexpanders. Double pre-expansion or optimized machines can achieve even lower densities.
Molding Compatibility: Works well within a wide range of steaming settings in standard industry molding machines.
