Harmonization Code : 3919.90.80.99 |   Polyacrylic plates / sheets / film / tape / strip, self-adhesive, in rolls
Main features
  • 91% Light transmittance
  • 1 Optical haze
  • Acid free

Product Description

LINQTAPE OCA is a film made out of Optically Clear Adhesive (OCA) backed on a PET substrate. OCA is a double-sided adhesive tape that is matrix-free, meaning it contains no supporting material.

LINQTAPE OCA has exceptional high visible light transmittance and low resistivity, making OCA film one of the most versatile and high-performance conductive materials available.

 

Applications include:

  • Transparent device bonding: With exceptional light transmittance of up to 91%, our OCA Film guarantees crystal-clear visibility within the visible spectral region.
  • Display assembly: With exceptional light transmittance of up to 91%, our OCA Film guarantees crystal-clear visibility within the visible spectral region.
  • Areospace and militairy optic assembly: With exceptional light transmittance of up to 91%, our OCA Film guarantees crystal-clear visibility within the visible spectral region.
  • Lenses: With exceptional light transmittance of up to 91%, our OCA Film guarantees crystal-clear visibility within the visible spectral region.

Adhesive Layer
Adhesive Layer
A layer that is applied to one surface or both to bind items together and resist their separation
 Acrylic
Adhesive Thickness
Adhesive Thickness
Adhesive thickness indicates the thickness of an adhesive layer.

It refers to the adhesive thickness of a single side so for double sided tapes it always needs to be multiplied.

Release Liner
Release Liner
A paper or plastic-based film sheet used to prevent a sticky surface from prematurely adhering

Total Thickness
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
 60 μm
Mechanical Properties
Adhesion Strength
Adhesion Strength
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other.
