Technical Information & Molding Conditions
Temperature Dependence
SA grade maintains stable hardness from room temperature to around 80°C. It also has relatively good heat resistance for a soft resin.
Shore A Hardness
Dynamic Viscoelasticity Data
Measuring method: Tensile mode, sine wave, frequency 11.0 Hz, temperature rise method (temperature rise rate 3°C/min)
Test piece: Pressed piece
Stress-Strain Curve
Specimen: 3mmt (press-formed)
Test speed: 500mm/min
Capillary Flow Data
Soft material that maintains high viscosity even in a high temperature range, enabling good profile extrudability and complex cross-sectional shapes.
Please Contact Us if you need temperature-specific data for each brand.
*No data for soft PVC (A65) at 220°C because it cannot be measured.
Compatibility with Other Resins (Two-Color Moldability)
SA grades have high affinity for a variety of polar resins and good thermal adhesion.
Therefore, composites with multiple resins by two-color molding, insert molding, co-extrusion molding, etc. are possible.
