Description

P-4000 is a specialized grade of expandable polystyrene (EPS) resin incorporating pentane as the foam blowing agent. This high-expansion material delivers exceptional insulation properties, moisture resistance, and significant mechanical load-bearing capacity. The ivory-white pearl-like spherical beads are engineered for optimal processing characteristics, making P-4000 particularly valuable for applications requiring precise dimensional stability and thermal performance.

  • Superior expansion ratio: Achieves densities down to 15 g/l after single expansion and 12 g/l after secondary expansion
  • Exceptional steam reactivity: Enables rapid processing cycles
  • High blowing agent content: Minimum 6.0% by weight pentane content
  • Controlled bead size distribution: ≥99.0% within 0.5-0.8 mm range
  • Enhanced recyclability: Accommodates higher recycled material content without significant property degradation
  • Zero CFC content: Environmentally compliant foam blowing technology

P-4000 EPS demonstrates superior performance across multiple construction and insulation applications:

  • Rigid insulation boards for thermal envelope systems
  • Panel applications requiring dimensional stability
  • Low-density housing and construction blocks for lightweight structural components
  • Civil engineering projects where moisture resistance and mechanical strength are critical

  • Accelerated production cycles: Fast molding capabilities reduce manufacturing time and increase throughput
  • Reduced material costs: Higher tolerance for recycled content integration
  • Enhanced thermal performance: Superior insulation characteristics reduce energy consumption in final applications
  • Consistent dimensional stability: Uniform bead size distribution ensures predictable expansion and finished product quality
  • Moisture resistance: Protects against water infiltration in building applications
  • Structural integrity: Maintains mechanical properties under load conditions

  • Insulation system manufacturers: Companies producing rigid thermal insulation products
  • Construction component fabricators: Manufacturers of lightweight structural elements
  • Civil engineering contractors: Professionals requiring moisture-resistant, insulating materials
  • Custom molding operations: Facilities processing EPS into specialized components
  • Recycling-focused operations: Manufacturers integrating recycled content into new products

P-4000 EPS is available in two standardized packaging configurations:

  • Standard packaging: 25 kg woven polypropylene laminated double-layered Kraft sacks
    • Provides optimal material protection during transport and storage
    • Manageable unit size for manual handling operations
  • Bulk packaging: 1000 kg polypropylene jumbo bags
    • Designed for high-volume processing operations
    • Reduces packaging waste and handling requirements
    • Compatible with standard lifting equipment

Storage Requirements:

    • Indoor storage in dry, cool, well-ventilated areas
    • Protection from direct sunlight, heat, flame, and precipitation
    • Temperature maintained below 20°C for optimal material stability
    • Prompt usage after package opening to maintain material properties
