Chrysler Bending Tester
1. Product Introduction & Applications
The Chrysler Bending Tester is designed to evaluate the bending and folding performance of coated fabrics and leather, assessing the mechanical stability and adhesion of coatings. It is based on the Chrysler Laboratory Test Method LP-463LB-9-01.
Applications:
Evaluates adhesion and mechanical stability of vinyl-coated fabrics, leather, and similar materials.
Detects whitening, cracking, lamellar separation, and unsupported rupture in coatings.
Applicable to soft furnishings, leather products, and vinyl-coated materials.
Simultaneous testing of multiple specimens for bending and folding behavior.
2. Product Advantages
Simultaneous Multi-Sample Testing: Four specimens can be tested at once — three for bending and one for folding.
Controlled Tension: Adjustable weights ensure consistent tension on bending specimens.
Adjustable Loads: Bending and folding loads can be set according to test requirements.
Quantitative Evaluation: Measures the coating’s resistance to mechanical stress and folding fatigue.
Electronic Counter: Six-digit counter tracks the number of cycles for precise monitoring.
Desktop Design: Compact structure suitable for lab benchtop use.
3. Product Features
Bending Test:
Three stations for bending specimens.
Sample clamped at both ends; one end fixed, the other moves horizontally.
Tension applied with fixed weight; 36 N (8 lbf.) bending load, adjustable.
Folding Test:
One station for folding specimen.
Sample clamped between opposing plates; 641 N (12 lbf.) folding load applied.
Ensures controlled and uniform pressure during fold.
Sample Sizes:
Bend specimens: 76 × 203 mm (3 × 8 in)
Folding specimen: 129 × 129 mm (5 × 5 in)
Cycle Tracking:
Manually resettable electronic counter.
6-digit display for precise cycle counting.
Compact Desktop Design:
Desktop footprint with durable mechanical construction.
Easy operation and sample replacement.
