Laser surface texturing for anti-adhesion in EPDM processing

Overview

Laser Surface Texturing (LST) offers an innovative approach to reduce self-adhesion in EPDM rubber processing by introducing micro/nanoscale surface patterns. This method aims to eliminate the need for conventional dusting agents, which pose contamination risks and environmental concerns. By optimizing laser parameters such as pulse duration, energy, and spacing, LST creates hierarchical structures that minimize adhesive forces, offering a scalable and cost-effective solution for synthetic rubber manufacturing.
