Easy installation with a uniform nish
Can be formed by hand
Stored in a straight condition to save storage space
No special installation tools required
Patented technology ensures industry leading heat transfer
Up to 75% sheath contact with round and square hotex
heaters when recommended groove geometry is followed
Rapid heat-up times
Minimal temperature difference between heater sheath
and heated tool
3-dimensional groove geometry possible
Industry’s smallest bending radius
Hotex’s exibility enables heat to be located where it is
needed; an improvement over rigid cartridge heaters
Reduced energy costs: tool mass can be reduced
