Cut from 2mm thick FS4004 graphite material, with self-adhesive backing on one side. The activation temperature is 288°C and they expand 80 times their own volume with an expansion pressure of 0.09 N/mm². ZHP44 intumescent hinge pads are supplied in packs of six pre-cut pieces with full installation instructions.
The depth of rebate should be increased when cutting out for the hinge. Apply the pad to the back of hinge using self-adhesive backing and trim to size if necessary. Fit the hinge in the normal fashion, screwing through the intumescent pads, ensuring hinges are flush with door/frame.
Intumescent hinge pads cannot be tested as a stand-alone product. Each situation is different. Performance is dependent upon the door specification and hinge specification and the interaction between each of these components. However FS4004 type intumescent is a well proven material which has been included in many successful fire tests in various applications over years. This offers confidence to manufacturers wishing to adopt a reliable hinge pad material where situations demand.
Hinge pads are available in five sizes to suit all regular size hinges; 102x76mm, 102x89mm, 102x102mm, 114x102mm and 114x114mm. They are available with square corners as standard, but can also be supplied with two 10mm radius corners to suit radius corner hinges. Suffix ref -R instead of -S.
