Fully compliant with ISO 9001:2015, RoHS, REACH, and ASTM standards. 

Processing Guidelines

• Foam Molding: 1–3% blowing agent (azodicarbonamide or CO₂); mold at 160–180°C; density 40–150 kg/m³ 
• Injection/Sheet Molding: Barrel 150–180°C; MFI 2.0 ensures smooth cavity fill, minimal defects 
• Extrusion: Tubes, strips, profiles; process at 150–180°C; avoid >190°C 
• Best Practices: Keep material dry, avoid excessive residence time, regular purging 

Performance Advantages 

• Foaming: Uniform expansion, fine cell structure, minimal voids—critical for comfort and durability 
• Mechanical: High tensile strength (260 kgf/cm²), elongation (~750%), 92 Shore A hardness 
• Temperature: Low melting point (86°C) reduces energy use, shortens cycle times 
• Chemical/Environmental: Resistant to oxidation, UV, ozone, common chemicals; flexible to -40°C
