Adhesive tape retentivity testers play a major role in evaluating the long-term performance of pressure-sensitive adhesive (PSA) tapes. These devices are essential for measuring the adhesion shear strength, which reflects the tape's ability to maintain adhesion under stress over time. Qualitest offers advanced solutions for this crucial testing process, adhering to industry standards such as ASTM D3654, PSTC 107, and JIS Z0237.

These standards provide guidelines for evaluating the holding power of adhesive tapes under specific conditions, ensuring consistency and reliability. Qualitest's product range includes three models designed for testing adhesion shear strength at ambient temperature and one model that can perform tests in a temperature chamber, capable of reaching up to 200°C. These testers are ideal for ensuring the durability and performance of PSA tapes across various industrial applications.
