resistancefor filmfor textiles

C680M Tearing Tester is suitable for testing tear resistance of film, sheet, soft PVC, PVDC,water-proof roll, woven material, polyolefin, polyester, paper, paperboard,textile and non-woven fabric, etc. Features Computer control, automatic electronic measurement, easy to operate. Pneumatic sample clamping and automatic pendulum release can effectively avoid the systematic error caused by human factors. Computer assisted adjustment system can ensure the instrument is always in the best test state. It can be equipped with multiple groups of pendulum capacity to meet different test requirements. Professional software supports the data output of various test units. Standard RS232 interface is convenient for external access and data transmission of the system. Test Principle Lift the pendulum to a certain height to make it have a certain potential energy; when the pendulum swings freely, it uses its own stored energy to tear the sample; the computer control system calculates the energy consumed in tearing the sample, so as to obtain the force required for tearing the sample.
