Description
PW-UCD80-40 Stress Relaxation Tester
It finds wide application in rubber, plastic, polymer materials, adhesives, and adhesive tape industries. It tests tensile strength, elongation, Poisson’s ratio, flat compression strength, compressibility, and fatigue performance of samples under normal, low, and high temperatures. Users can switch between temperature modes with ease, achieving high efficiency and multi‑functionality in one machine.
Features a dual-column structure with three working stations operating in sync.
