Key Features & Benefits for Extrusion Manufacturers
Unmatched Mechanical Performance: High K-value delivers superior tensile strength, stiffness, and long-term creep resistance, ensuring product integrity under stress.
Superior Impact Resistance: Excellent inherent toughness makes it ideal for applications prone to mechanical shock or pressure, significantly reducing failure rates.
Enhanced Thermal Properties: Higher Vicat Softening Temperature provides improved dimensional stability in high-temperature environments and during hot-fill processes.
High Purity & Clarity: Low fish eye count and exceptional purity allow for the production of crystal-clear products, perfect for premium packaging.
Excellent Processability: Free-flowing powder with a porous structure ensures rapid, uniform dry blending, efficient gelation, and smooth processing in extrusion, injection moulding, and blow moulding.
Regulatory Compliance: We offer standard and food-grade qualities that comply with major international standards, including FDA, EFSA, and REACH for specific applications.
Applications
SG-3 resin is the material of choice for engineers and product developers requiring enhanced performance:
Blow Moulding:
Clear Bottles: Mineral water, edible oil, vinegar, and pharmaceutical bottles.
Technical Containers: Chemical and industrial packaging.
Extrusion:
High-Pressure Pipes: Industrial and chemical pressure pipes.
Profile & Sheet Extrusion: High-strength technical profiles, solid sheets for construction and fabrication.
Cable & Wire: Insulation and jacketing requiring good mechanical properties.
Injection Moulding:
Robust Fittings: High-performance pipe fittings, valves, and mechanical parts.
Technical Parts: Durable components for appliances and automotive interiors.
Calendering:
Rigid Sheets & Foam Boards: For signage, chemical storage tanks, and partitioning.
Processing Recommendations
Blending: Excellent dry blend characteristics. Standard mixing sequences apply.
Extrusion: Requires a robust twin-screw extruder. Processing temperatures are typically 5-15°C higher than for standard K67 resin to achieve optimal fusion. Ensure adequate lubrication balance.
Injection Moulding: Higher injection pressures and temperatures may be required compared to lower K-value resins.
Blow Moulding: Excellent parison control and melt strength for consistent bottle production.
Note: We highly recommend conducting trials to fine-tune your specific formulation and machine parameters for optimal results.
