Testador de aderência de loop LTT-01

The Tape Loop Tack Testing Machine, also known as the Testador de aderência de loop LTT-01, is an advanced testing instrument designed to measure the tackiness, adhesive strength, and sticking force of pressure-sensitive adhesives. This machine is essential for industries where adhesive performance is crucial, including packaging, medical devices, pharmaceuticals, electronics, e quality inspection. Its precision and adherence to established standards make it a reliable tool for manufacturers and quality control teams aiming to ensure optimal adhesive properties.

What is Loop Tack Testing?

Loop tack testing evaluates the initial strength of an adhesive bond when it first contacts another surface. In this test, the tack force—or the force required to separate an adhesive from its contact surface immediately after bonding—is measured. The loop tack test is invaluable for quality assurance, especially for products like tapes, labels, and stickers, where immediate adhesiveness is a critical attribute.

Adherence to ASTM D6195 Standards

The Tape Loop Tack Testing Machine is fully compliant with ASTM D6195, which outlines the standard test method for measuring loop tack of pressure-sensitive adhesives. This standard ensures the accuracy, repeatability, and reliability of results across different testing scenarios.

• ASTM D6195 Test Methodology:
  • A sample adhesive strip, sized at 25mm wide and 175mm long, is formed into a loop and brought into contact with a standard glass plate at a speed of 300mm/min.
  • After making initial contact, the adhesive is separated from the glass at the same speed, and the maximum force required to break the bond is recorded, representing the loop tack.
• Following ASTM D6195 guarantees consistent testing standards, enabling accurate quality assessments of adhesive materials for regulatory and consumer safety.

Key Standards Compliance

In addition to ASTM D6195, the Tape Loop Tack Testing Machine adheres to other global standards, reinforcing its applicability across diverse markets:

• FINAT Test Method No. 9 (FTM-9) – This European standard is widely recognized for testing pressure-sensitive adhesives.
• PSTC-16 Loop Tack – A North American standard dedicated to the tack testing of adhesive tapes.
