Skived

PTFE STANDARD SKIVED TEKFILM

Tekfilm skived PTFE is produced by compression molding a large cylindrical billet and “skiving” the film off of the billet in a lathe.
Standard, modified, conductive and anthistatic, pigmented PTFE grades available in a wide range of thicknesses with tigth tollerances.

GFI - ULTRA FLAT PTFE SKIVED TEKFILM

A proprietary flattening process is used to produce an ultraflat film eliminating the curling effect typical of the PTFE skived film.

CODE	TYPE	THICKNESS (mm)	MAX WIDTH (mm)	COLOUR	ROLL LENGTH
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
