DESCRIPTION

Pyrostrip® 300 has been developed for use with various types of fire resistant glass, to provide at least 30 minutes fire resistance in accordance with BS476 Part 22: 1987.

Pyrostrip® 300 is a phosphate based multi-component intumescent system. Under the action of heat, the components react chemically to form a soft, high volumetric expanded char that will seal gaps which occur during a fire.

Pyrostrip® 300 also has insulating properties to protect substrates such as timber, when exposed to fire. Pyrostrip 300 is 2mm thick.

Pyrostrip® 300 has achieved in excess of 30 minutes integrity to BS476:Part 22: 1987. Examples of tested construction as follows:

 



69484/A Glazed aperture 578mm x 908mm in Sauerland Type 38RF door core.

69484/B Glazed aperture 578mm x 908mm in Sauerland Type 38PV door core.RF 95045 Glazed aperture 370mm x 270mm in softwood laminated door core.
70603 Glazed aperture 730mm x 1755mm (Pyran S) in single acting, double leaf, glazed doorset.

Pyrostrip® 300 is a non-pressure developing intumescent seal, which produces high volumetric expansion when exposed to heat. The binder system employed in the manufacture of the product means Pyrostrip® 300 is flexible in its cold state.

Pyrostrip® 300 intumesces at
approximately 160°C.

 

 



The blowing agents react and expand the insulating char material to around 40 times its original volume.

Pyrostrip® 300 seals can be used as a glazing seal within glazed apertures of fire resisting doors.

Pyrostrip® 300 is available in white and brown and can be supplied as self-adhesive for ease of fixing.

Pyrostrip® 300 can be supplied in 10 metre coils and is easily cut to length, using a sharp knife or scissors, however, we can cut to length if required.
