Permatek® HP
A high performance polymeric dispersion formulated especially for use on fire
hose jackets. By the nature of the polymer and the process by which it is
applied Permatek® HP virtually encapsulates every fibre of the substrate
thereby imparting superior physical properties.
Performance When Applied to Sample Hose
| U.V. Resistance |
Excellent |
No deterioration after 600 hours U.V. exposure (equivalent to 2 years of
sunlight). |
| Fungal Resistance |
Excellent |
Does not support fungal growth |
| Heat Resistance |
Good |
A 4" propane flame held 1" from the hose took 18 seconds to burn
through. |
| Water Retention |
Minimal |
Two identical pieces of hose, one treated with Permatek® HP and the other
untreated, soaked in tap water for 1 hour. After drip drying for 3 minutes the
untreated hose gained 44% of its weight while the Permatek® HP treated hose
gained only 25%. |
| Abrasion Resistance |
Excellent |
Depending on the type of hose tested, an increase of 100% to 400% in the
ability of the hose to withstand abrasion may be realized with Permatek® HP
protection when checked with a standard F.M. Abrasion Tester. Using a Taber
Abrasion Tester a 500% to 600% increase may be expected. |
