Thermef

THERMEF: 100% Saturated D.M.D. laminate Class F insulation (155°C). Thermef is a D.M.D. laminate (polyester non woven fibermat/polyester film/polyester non woven fibermat), that is 100% saturated with class H resins to obtain thermal index 155°C according to A.S.T.M. D-1830. The resin is hot-cured so that it is permanent and non melting. The polyester film is heat-stabilized to minimize shrinkage at 150°C.

Polyesterfolie

Polyester film based flexible composites

Polyester film can be laminated to one or more different flexible substrates, e.g. plastic films, papers, fabric, metal foils, etc., thus obtaining composite materials having outstanding technical qualities, for example:
  • greater tensile strenght and elongation

  • improved tear strength (initial and propagating)

  • increased thermal index from class 130°C (B) to class 155°C (F)

  • greater adhesion of impregnating resins

  • improved heat dissipation

  • prevention of polyester oxydation

  • higher insulation properties

  • resulting in true cost reduction benefits

Polipress

LP COMPOSITE: pressboard-polyester film lamination

Class B insulation (130°C).


LP Composite is a lamination of polyester film 23 or 50 microns thick (1 or 2 mils), laminated to one or two layers of prssboard paper of varying thickness. When laminated to polyester film, pressboard papers have good tear resistance and exellent flexibility along with good dielectric properties in conditions of high humidity.

Politrix

Politrix: Kraft/Polyester/Kraft lamination

Class B insulation (130°C).


Politrix is produced by laminating polyester film between two layers of kraft paper, thus giving outstanding electrical and mechanical properties, plus the protection of the polyester film from oxydation. This makes Politrix suitable for insulation in low and medium tension electrical machines. Politrix can be easily impregnated and has good tear strength.

DMD

DMD: Polyester fibermat/film lamination 70% saturated

Class B/F insulation (130/155°C).


D.M.D. is produced by laminating polyester film to two outer layers of polyester non-woven fibermat. The lamination process is made with a heat resistant adhsive system which encloses and protects the film at elevated temperature and gives 70% saturation. Once impregnated the material is thermally upgraded dependant on the type of resin used.
