Accurately measure adhesive bond strength and seal consistency. Our systems support standard 90°, 180°, and T-peel testing configurations for tapes, laminates, and medical packaging.
Peel testing is a critical quality assurance method used to measure the adhesive strength between bonded materials. ADMET offers advanced peel testing machines designed to accurately assess the peel strength of a wide range of materials and products, including elastomers, adhesives, glues, cement, laminates, packaging, fabrics, coatings, labels, tapes, medical devices, and more. Whether developing new materials or performing routine quality control, peel testing helps ensure the reliability and durability of adhesive bonds under various service conditions.
Peel Testing Definitions and Theory
What is Peel Testing?
Peel testing determines the average load per unit width required to gradually separate a flexible material from a rigid substrate or from another flexible member. It measures the force needed to peel apart bonded surfaces, providing quantitative data on bond strength. Peel strength is typically expressed in kilograms per millimeter (kg/mm) or pounds per inch (lb/in), calculated by dividing the average force exerted during peeling by the bond width.
ADMET peel testing systems operate under constant-rate-of-extension (CRE) or constant-rate-of-load (CRL) control. This versatility allows users to perform numerous adhesive-related tests using a single testing machine, making it an efficient and cost-effective solution.
Why is Peel Testing Important?
Peel testing plays a vital role in industries that rely on adhesive bonds to maintain product integrity and performance. Accurate peel strength measurement ensures that materials meet customer requirements and industry standards, preventing premature failures and costly recalls.
By understanding peel strength, manufacturers can optimize adhesives and bonding processes to improve product durability, flexibility, and safety. Peel testing also helps evaluate the effects of environmental factors such as temperature, humidity, or aging, ensuring that adhesion remains effective throughout the product lifecycle.
Common Peel Testing Types
ADMET systems support a variety of peel test methods, each suited to specific materials and applications:
- T-Peel Test: Measures peel separation strength between two flexible materials bonded together (ASTM D1876).
- 90-Degree Peel Test: Measures peel strength of a flexible material adhered to a substrate at a 90-degree angle.
- 180-Degree Peel Test: Similar to the 90-degree peel but peeling occurs at 180 degrees (ASTM D3330).
- Floating Roller Peel Test: Provides gentle peeling for materials that cannot bend to 90 or 180 degrees (ASTM D3167).
- Climbing Peel Drum Test: Measures peel resistance of dissimilar materials by applying pure peeling force (ASTM D1781).
- Loop Tack Strength Test: Measures the tack force or initial stickiness of pressure-sensitive adhesives (PSA) (ASTM D6195).
ADMET also offers specialized fixtures for performing these tests, ensuring precise sample holding and repeatable results.
