Chemours Teflon industrial coatings are used in the paper industry to improve the efficiency of paper mills, pulp mills and related paper converting industries. In these industries, fiber can stick to process equipment, resulting in expensive downtime for cleaning. In addition, the agglomeration of fibers can often cause quality problems in the finished paper product.
Teflon industrial coatings are offered in two categories:
1 Bake Systems
With these systems, Teflon PFA or FEP is applied to the appropriate equipment (typically a drying cylinder) and then baked at a high temperature. Because of the need for a high temperature bake (up to 380 C/715 F), the equipment to be coated is usually transported to a applicator.
In special cases where additional abrasion resistance is required, Teflon is applied over a plasma or metal sprayed substrate.
The benefits to the mill are reduced paper ripping or sticking to a coated drying cylinder, resulting in increased mill efficiency.
2 Non-Bake Systems
The traditional Bake Systems can be difficult to apply since the equipment needs to be transported to an oven. For this reason, Teflon offers a non-bake alternative.
The Non-Bake system has been proven to reduce the downtime associated with the cleaning of:
Teflon also allows press rollers to be doctored. Because of the improved nonstick, Teflon industrial coatings increase the life of the doctor blade.
Teflon systems have been successfully used on a wide range of surfaces:
