Chemlam high performance laminates are manufactured from chemfilm advanced fluoropolymer films, bonded to fiberglass, aramid substrates. These composites exceed Dotmar’s customers expectations in applications where resistance to chemical, heat and sticking are demanding.
The coatings are built up in layers (similar to multiple dipping of a candle) to produce crack and pinhole-free surfaces suitable for applications ranging from food, beverage, chemical and plastics processing and packaging to energy, environmental and protective systems requiring low chemical permeation, easy decontamination, flame resistance and outdoor durability.
The lack of cracks and pinholes offer many important benefits, including ease of cleaning, because there are no anchor points for contaminates. And because the laminates protect their reinforcement materials better, the belt or surface retains its mechanical properties longer. |

Applications of the technology include:
- Quick serve food processing.
- Industrial food processing.
- Plastic packaging and processing.
- Expansion joints requiring qualities such as low permeability, chemical compatibility, environmental stability and outstanding protection of reinforcement to delay loss in mechanical properties.
- Protective systems, including Hazmat chemical suits and protective tents required in many industries, including chemical, petrochemical and minerals processing.
- Speciality laminates, where normally incompatible materials are combined to the desirable properties of each. Examples include roll covers on printing presses and friction management in shoes and prosthetics.
- Specialised applications including chute linings, heat sealing jaw covers, covers for platens, rollers and dryer cans, drying oven curtains, splash curtains and aprons, mandrel covers, weigh pan covers, insulation gaskets, trough and tray liners.

The superior mechanical properties produced by Chemlam means thinner materials can be used, as a result of this, the temperature of platens or heat sealing bars can be reduced, offering a lower operating cost due to less heat energy being required. The range of substrates that can be coated is extensive - Aramids include high-strength highly flexible materials such as Kevlar® and Nomex®, while speciality substrates include cotton, polyester, Lycra® and others.

Chemlam coatings have high dielectric strength, extreme thermal range (–150°C to +260°C), exceptional dimensional stability, outstanding fire resistance, low shrinkage and flex resistance.
