Give your products the moisture protection they require with HydroBlock® barrier films. These industrial-grade polychlorotrifluoroethylene (PCTFE) films offer class-leading moisture barrier capability at a lower cost than traditional barrier films used in non-food and non-medical applications.


Product Feature Overview

Moisture Protection

When compared with fluorinated ethylene propylene (FEP) and polyvinyldene fluoride (PVDF) films, HydroBlock PCTFE films offer the superior moisture barrier you need for the most demanding industrial applications, such as outdoor signage.

Chemical and Weather Resistance

HydroBlock offers excellent chemical resistance, making it a clear choice for products that need to withstand harsh environments, such as lab bench liners and graffiti-resistant surfaces. The material also resists the odors, ultraviolet light and sub-zero temperatures outdoor products must endure, making it ideal for sensor casings and other applications where durability is required.


As one of the clearest industrial barrier films available today, HydroBlock is suitable for use in industrial packaging and electroluminescent lamps.


HydroBlock films can be thermoformed or vacuum formed to meet the needs of your application. They can also be laminated to other films, or coated with heat seal adhesives. Contact Honeywell’s technical service team today to find out which grade of HydroBlock can work for your application.
