Ozone Resistant Test Chamber

In operation the rubber materials deteriorate when exposed to ozone. Thus it is vey important to have test methods in which simple, accelerated time/exposure, comparisons of the material’s ability to resist cracking caused by ozone exposure can be empirically evaluated.

N-Wissen GmbH is glad to present the new Ozone Resistant Chamber OZT-QL-15040 for testing rubber materials and components according to the following standards:

  • ASTM D1149 – 18 “Standard Test Methods for Rubber Deterioration – Cracking in an Ozone Controlled Environment”
  • ISO 1431-3:2017 “Rubber, vulcanized or thermoplastic – Resistance to ozone cracking”

High-efficient autoclaves for defoaming LCD panels

N-Wissen GmbH introduces the new generation of already very well known YYK series autoclaves amoung our customers across the whole Europe.
These autoclaves are used for high-efficient dispersing (purging) the residual air bubbles in cell panels after polarizer aligning process in LCD production. By applying uniform pressure while heating work piece in chamber, it not only removes bubbles but also increases adhesive strength in an instant.
It can also crush bubbles entrained during resin-molding of electronic components by pressurization and cure the resin by heating.
