Wear-resistant non-adhesive coating for foam manufacturing
A silicon and oxygen-modified DLC coating designed to enhance demolding efficiency and eliminate the need for liquid mold release agents in rigid polyisocyanurate foam manufacturing. Offers superior wear resistance and temperature stability.
Overview
The wear-resistant non-adhesive coating is an innovative solution designed to improve the manufacturing process of rigid polyisocyanurate foam. By applying a silicon and oxygen-modified diamond-like carbon (DLC) coating to the mold's side metal plates, this technology significantly reduces foam adhesion. This advancement enhances demolding efficiency, potentially eliminating the need for traditional liquid mold release agents, thus simplifying the process, lowering costs, and reducing environmental impact. Additionally, more consistent demolding can lead to improved product quality.
