TPE Test Methods
TPE Testing Capabilities at Sutper R&D Lab
Hardness Testing
Test Standard: ASTM D 2240
Aim: determine the material's hardness, which helps assess its suitability for different applications. This ensures the TPE meets the required levels of softness or firmness for optimal performance in specific products.
Test Device: Shore Durometer (A&D)
Density Measurement
Test Standard: ASTM D 792
Aim: determine the material's mass per unit volume, which helps ensure consistency in product quality, performance, and suitability for specific applications. This data is crucial for material selection, production control, and meeting industry standards.
Test Device: Analytical balance and density kit
Compression Set
Test Standard: ASTM D 395
Aim: Evaluate the material's ability to return to its original shape after prolonged compression. This helps determine the material's long-term elasticity, durability, and suitability for applications requiring resistance to permanent deformation.
Test Device: Compression set tester
Tensile Strength and Elongation Testing
Test Standard: ASTM D 412
Aim: evaluate the material's ability to withstand stretching forces without breaking and to measure how much it can elongate before failure. This helps determine the material's strength, flexibility, and suitability for applications where tensile forces are present, ensuring it meets performance and safety standards.
Test Device: universal testing machine (UTM)
Tear Strength Test
Test Standard: ASTM D 624
Aim: Measuring the tear resistance of thermoplastic elastomers.
Test Device: universal testing machine (UTM)
Melt Flow Index (MFI)
Test Standard: ASTM D 1238
Aim: Measuring the melt flow index of molten thermoplastic elastomers.
Test Device: Melt Flow Index tester
Color Measurement (L.a.b.)
Aim: Measuring the lightness (L value), red-green (a value), and yellow-blue (b value) of thermoplastic elastomers.
Test Device: Colorimeter
Kinematic Viscosity Test
Aim: Measuring the viscosity of liquids or dissolved solids.
Test Device: Kinematic viscometer
Humidity Test
Aim: Measuring the humidity of thermoplastic elastomers by quantifying weight loss.
Test Device: Hygrometer
Odor Test
Aim: Grading thermoplastic elastomers based on odor levels.
Test Device: Odor vial
UV Aging Test
Aim: Observing the changes in thermoplastic elastomers under ultraviolet light.
