Polar tensile testing machine

Polar tensile testing machine

The pole tensile tester is mainly used for testing and analyzing the mechanical properties of metal and non-metallic materials (including composite materials), lithium batteries, adhesives, adhesive tapes, stickers, medical adhesives, protective films, release paper, composite films, plastic packaging for food bags, plastic packaging for daily cosmetics, artificial leather, woven bags, films, paper, such as tension, compression, bending, puncture, peeling, tearing, etc., with stress, strain Three closed-loop control modes of displacement can be used to calculate parameters such as force, tensile strength, bending strength, compression strength, elastic modulus, elongation at break, yield strength, etc.

Test and provide test data according to GB, ISO, JIS, ASTM, DIN and other standards.
