Need an effective weatherproof seal? Talk to J-Flex!


J-Flex Products In Action

Our Customer:

A large European producer of specialised electronic and electrical lighting equipment for airports & heliports.



The Requirements:

A suitable flat gasket material to create an effective permanent weatherproof seal, even after long term exposure to external weather conditions.

A material that gives no outgassing when heated in light fittings to high temperatures of 150°- 185°C.


The Problem:

OUTGASSING!!

Outgassing is defined as the release of a gas that was dissolved, trapped, frozen or absorbed in some materials. Evidence of outgassing is shown as a thin film deposited on surrounding surfaces. Some materials exhibit some degree of water vapour causing misting (fogging) of glass or plastic surfaces.

Outgassing is a challenge to lighting equipment producers, to create & maintain condensate  free glass lighting products.

Some traditional rubber seal materials outgas when installed in light fittings, as temperature rises it manifests itself as a condensate  fog on the inside of the light glass.

Silicone if processed correctly does not outgas. Thermally Silicone is one of the most stable elastomer materials available, capable of working over a wide temperature range – typically -40°C + 230°C continually.

A pre-requisite of correct processing is post curing. This additional heat conditioning process, or secondary curing, removes unwanted volatiles by diffusion and evaporation. This is carried out at high temperatures & once the volatiles are vapourised they are no longer available to outgas. Some traditional rubber materials, and some producers, do not advocate the use of post curing.
