T-impact peel strength tester for structural adhesives

This instrument is suitable for determining the T‑impact peel length, an important indicator of the toughness of room‑temperature‑curing structural adhesives. A T‑impact peel specimen is prepared by bonding a pair of thin mild‑steel sheets; under specified conditions, an impact force is applied to the unbonded end of the specimen, causing delamination along the bond line. Structural adhesives with differing toughness exhibit markedly different peel lengths, allowing their relative toughness to be assessed. By measuring the peel length and conducting comparative analyses of test data for various adhesive grades, it is possible to establish a simple, practical acceptance criterion for structural adhesive toughness, based on peel length.

T-impact peel strength tester for structural adhesives

Description

Product Introduction:

This instrument is suitable for determining the T‑impact peel length, an important indicator of the toughness of room‑temperature‑curing structural adhesives. A T‑impact peel specimen is prepared by bonding a pair of thin mild‑steel sheets; under specified conditions, an impact force is applied to the unbonded end of the specimen, causing delamination along the adhesive joint. Structural adhesives with differing toughness exhibit markedly different peel lengths, allowing their relative toughness to be assessed. By measuring the peel length and conducting comparative analyses of test data for various adhesive grades, it is possible to establish a simple, practical acceptance criterion for structural adhesive toughness, based on peel length.

Can you customize fixtures or test machines based on our special test requirements? How about after-sales service and warranty?

We provide non-standard customization of test equipment and customized fixture clamps according to customers’ specimen size and test standards. All our testing machines enjoy 12-month factory warranty; overseas customers get remote online debugging guidance, spare parts supply and technical operation training. Our products have been exported to over 70 countries globally

Which materials can be measured by your Vicat softening point tester?

It measures heat deflection temperature and Vicat softening temperature of plastics, hard rubber, nylon, insulating materials and fiber-reinforced thermosetting composites. Intelligent temperature control guarantees precise heating rate, ideal for plastic raw material incoming inspection and formula development in plastic factories.

Does your pipe pressure burst testing machine control test temperature automatically? What’s its main application?

Yes, the constant-temperature circulating system keeps stable test environment during long-time hydrostatic resistance and instant burst pressure measurement of thermoplastic pipes. It complies with GB6111 standard and serves raw material inspection, new product R&D for plastic pipe manufacturers, third-party testing labs and university laboratories.

What kinds of pipes fit your ring stiffness tester? Can it do long-term creep testing?

This equipment is designed for HDPE, PVC corrugated pipes, plastic drainage pipes and various plastic tubular products. Apart from ring stiffness, ring flexibility and flattening tests, it supports continuous long-term creep tests up to 1000 hours (42 days) as required by industry specifications, widely used for pipe factories and construction quality inspection institutes.

What test items can your WDW series computer-controlled electronic universal testing machine complete? Which international standards can it meet?

Our WDW universal tester is applicable for tension, compression, bending, shearing and peeling tests of metal, plastic, rubber and composite materials. It supports test procedures in accordance with GB, ISO, ASTM, DIN, JIS multiple domestic and global standards. Equipped with high-precision servo drive and dedicated test software, it automatically collects, calculates and exports test data including tensile strength, elongation at break and elastic modulus.

Customer Reviews

European Plastic Pipe Manufacturer｜Purchase: Ring Stiffness & Hydrostatic Burst Tester

From Thomas Bennett, Quality Director, UK plastic pipe factory

2026.06.05

★★★★★

“We have purchased two sets of pipe testing equipment from Laibote (Tianjin) for 18 months. The ring stiffness and hydrostatic burst testing machines run stably for daily batch inspection, test data matches ISO standard requirements precisely, and the intelligent test software is easy for our operators to master. Their after-sales team offers timely remote technical guidance whenever we have operational problems, spare parts supply is efficient. We have arranged a second bulk order for our new production workshop and will recommend Laibote’s testing machines to our industry partners across Europe.”
