Fluorinated plastic coatings:
  • FEP
  • HALAR ®
  • PFA
  • PTFE
  • PVDF

 
Typical features of our PTFE plastic coatings:

     - anti-adhesive surface
     - good sliding
     - low friction coefficient
     - highest temperature resistance
     - good release properties



  Applications:


- general mechanics: Bolts, screws, bolts, fans, rotors, Reactors

- food confectionery industry: Rolling, baking pans, plates, mixers, hoppers, screw conveyors

- chemical and pharmaceutical industry: Dosing, conveying inner, mixers, valves, tanks, shelf trays, molds, mixers

- textile industry: Sliding rollers, damper rolls, dye tubs, drying cylinders

- paper industry: Drying cylinders, guide rollers, paint trays

- rubber and plastics industry: Heating sockets, calendar, forms, welding mirror

- packaging machinery: Stamping. Hot plates, under seal, Vorwärmeplatten, knives, molds, guide rails

...and wherever baking, to prevent sticking and low-wetting is necessary, or sliding and release properties are to be improved.



Procedure:

Depending on the application, the required properties and the stress we offer different types of procedures
and material combinations with plasma (Alu-oxide or VA-Mat.), hard chrome or aluminum hard-coated as a primer
