Quicktest 38®S Poly Testpen serves to check if the treatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect on the material. A stroke of the pen leaves a full line on the material if the material’s surface energy has a value of ca. 38 dyne/cm (mN/m) or more. If, however, the surface energy is lower than ca. 38 dyne/cm (mN/m), then the fluid contained in the pen will form small droplets on the surface.
