CHC technology has succeeded in maintaining the non-stick properties of heat plates compared to conventional fluoropolymer coatings (PTFE coatings)!
■Customer Request We want to eliminate stringing that occurs on the heating plate during the thermal welding of polyethylene containers. We aim to reduce product defects caused by stringing without changing the takt time and to decrease the frequency of heating plate replacement. ■Conditions for Process Selection As a result of considering cost-effectiveness, we require a lifespan that is double that of the current coating. ■Achieved Effects By adopting CHC technology for the coating, we have successfully balanced release effect and lifespan. *You can download a PDF summarizing the product information.

basic information
■What is CHC Technology? CHC technology is a method that prevents the reduction of coating strength in high-temperature environments, which is a weakness of fluororesins, enhances durability, and maintains excellent release properties in environments above 200°C. ■Features - Non-stick properties equivalent to PTFE and PFA - High film hardness at temperatures above 200°C (compared to PTFE) *Based on internal testing ■Applications - Resin welding plates - Resin molding molds - Heater plates *For product details, please download the PDF or refer to the link below. *For more information, please contact us.
