DIRAX heat shrink sleeve, Heat-shrink cuff Canusa-CPS
DIRAX includes:
- A heat-shrink wrap cuff, reinforced with (1) glass fiber and a pre-fastened lock and (2) a coat of hot-melt adhesive resistance to shear. (The special cuff reinforced with glass fiber makes the material highly abrasion-resistant but also keeps it flexible to follow pipe bends);
- A narrow cuff made of a narrow heat-shrink cuff reinforced with glass fiber and a fastened lock, and a coating from hot-melt adhesive resistant to shears;
- two-component epoxide primer.
Heat-shrink cuff Canusa-CPS is a two-layer system on a radiation-grafted polyolefine base covered inside with a hot-melt or mastic adhesive. Subject to project specifications and if a three-layer coating is used for pipe trunk insulation, the third layer could be applied – an epoxide primer – directly onto the pipe when the cuff is being installed onto a pipe to be laid.
