Detailed
The universal testing machine (UTM/tensile tester) is the core mechanical testing equipment in an adhesive lab. It can be configured with various fixtures for tension, compression, bending, peel, and shear tests, completing a full range of mechanical tests such as 180° peel strength, 90° peel strength, loop tack, tensile strength/elongation, holding power, and lap shear strength. The Instron 34/68 series, represented by Dehui, uses a brushless AC servo drive and digital closed-loop control, with a load accuracy of 0.5 class and speeds from 0.001 to 1500 mm/min. The Bluehill Universal software comes with built-in standard templates like ASTM D3330, ASTM D1002, and FINAT FTM. One Instron machine can handle over 90% of standard tests for adhesives—making it the top priority for new material labs.
- Standard tests for pressure-sensitive tape 180°/90° peel strength (ASTM D3330, GB/T 2792)
- Lap shear strength tests for structural/epoxy adhesives (ASTM D1002, ISO 4587)
- Tensile strength, elongation at break, and Young's modulus for tapes/films
- Standard release force tests for release films/papers (FINAT FTM 3/10)
- Holding power/shear creep under constant load—to evaluate tape resistance to long-term slipping
