GFI 400 Ultra Flat Film from 0,025 to 0,508 1500 Natural To customers’ specifications

CALFIM GF - CALENDERED PTFE SKIVED TEKFILM

Oriented high modulus PTFE skived films and tapes. The main benefit are:
  • higher elastic modulus
  • higher dieletric strength
  • lower porosity
  • reduced cold flow
  • better trasparency

LAS DOS GRANDES FAMILIAS DEL P.T.F.E.

** SUSPENSIONES **

Dos tipos de grados, Virgen o cargado, divididos en FF (Free Flowing) y NFF (No free flowing)

Se utilizan para fabricar Productos semielaborados y terminados como placas, barras, tubos, film etc.. para su posterior mecanizado

 

** EMULSIONES **

Dos tipos de grados: Dispersiones y Grados de extrusion de polvo fino

Las dispersiones se usan para la Formulación de sistemas de recubrimiento Impregnación Recubrimiento de tejidos de fibra de vidrio

Los grados de extrusion de polvo fino se usan para tubos de pared fina, cintas de estanqueidad (tipicas de fontanero) cintas aislantes electricas y como aislamiento de cables.

Una mezcla de las dos familias serian los MICROPOWDERS (Micropolvos) utilizados como Aditivos para plásticos, lubricantes y tintas de impresión Recubrimientos antiadherentes y antifricción

CADA FAMILIA CORRESPONDE A DISTINTOS PROCESOS DE TRANSFORMACIÓN Y PRODUCCIÓN que detallaremos en posteriores articulos.

Hasta aquí nuestro segundo articulo. Os esperamos en el siguiente para hablar de los procesos de produccion y de las multiples aplicaciones.
