Description

221HS is a high-strength, free-flowing expandable polystyrene (EPS) grade. It is made of spherical polystyrene beads containing pentane as the expansion agent. 221HS is designed for expansion to achieve low densities, formulated to produce low-density foam without lumps during pre-expansion. It is produced through the suspension polymerization method. 221HS is not fire retardant and is therefore not suitable for building applications requiring flame resistance.

  • High Strength: Formulated for high strength to achieve low-density foam
  • Antistatic Treatment: Treated with an antistatic agent to prevent static electricity build-up during transport and processing, ensuring smoother material flow
  • Versatility: Suitable for thermal insulation and protective packaging
  • Density: Achieves pre-expansion densities of around 20 kg/m3

Other performance characteristics:

  • Excellent heat insulation
  • Superior sound-proofing properties
  • High impact strength
  • Vibration resistance
  • Light resistance
  • Water repellency
  • Dustproofness
  • Resistance to physical processing

Chemical Resistance:

  • Resistant to hydrolysis
  • Resistant to oils
  • Resistant to acids
  • Resistant to alkali solutions

221HS is suited to producing medium to low-density foam blocks. Common applications include:

  • Thermal insulation boards for construction applications without specific flame resistance requirements
  • Packaging blanks
  • Cushioning material for protecting delicate items during shipping
  • Thin-wall goods and fire-resistant industrial and food packaging

The features of 221HS translate into several real-world advantages:

  • Cost Efficiency: High-speed implementation and cost reduction
  • Ease of Handling and Processing: Antistatic treatment minimizes handling issues
  • Thermal Efficiency: Provides effective insulation in construction
  • Impact Resistance: Ensures foam maintains structural integrity, offering impact resistance for packaging
  • Other benefits:
    Speed and ease of roof execution
    Save on plaster, dirt, and hardware
    Stable against earthquakes
    Easy shipping, being light
    Good resistance against water and other solvents

The primary user base for 221HS includes:

  • Construction companies requiring thermal insulation
  • Packaging manufacturers needing protective materials
  • Industries that require medium to low-density foam blocks

  • 221HS is shipped in jumbo bags or octabins on wooden pallets
  • Net Weight: 1000 kg per octabin
  • Octabin Dimensions: Height 158 cm, Pallet 115cm x 115 cm
  • Packaging: 55*25 Kg shrink-wrapped wooden pallets
  • The octabins are not weather or waterproof and should not be exposed to outdoor conditions
