Material
ZX-100K as replacement for polyamide

Description of the application
In this application it is about rolls in a adhesive roller machine. Previously as material polyamide was used.

Problem
In this application a high precision, dimensional stable and anti-adhesive material is required. The accuracy and precision of the clearance, which is extremely important for the  functionality of the machine, had to be improved. Polyamide should be replace because of its dimensional changes due to the high moisture absorption.

Problem-solving
Polyamide’s rolls were replaced from the ones made of ZX-100K.

Advantages
Higher precision, thereby precisely defi ned clearance (0,3 mm before, 0,03 mm now), anti-adhesive properties, better machinability and thereby cheaper, better surface quality. Higher wear resistance. The surface can be easily re-machined if necessary.
