Pendulum method propagation tear resistance tester determinates tear resistance property of films, sheets, flexible PVC, PVDC, waterproof films, woven materials, polypropylene, polyester, paper, cardboard, textile and non-woven, etc.
Principle: Acting by gravity, the pendulum swings through an arc, tearing the specimen from a precut slit. This loss in energy indicates the force required to tear the specimen.
