Description

The Ester tube is a tube braided with single thread, either, Polyester threads PET or PBT. 
It is used for cable protection.
The PET is an abbreviation of Polyester Terephtalate.
The PBT is an abbreviation of Polybutylene Terephtalate. This product is obtained by Polycondensation of Dimethylterephtalate DMT and of 1.4 Butanediol. With the properties listed below, the PBT is rated among the technical plastics.
 

 

  • Resistant to high temperatures (Superior to 473 k or 200c)
  •  Dimensional stability(al absorption virtually no water)
  •  Tenacity, resistance to creep.
  •  Remarkable fire resisting properties when used as fire proofing.

    Other important properties of PBT:
  •  Reliable rubbing coefficient.
  •  Good dielectric properties.
  • Good age – resistant qualities.
