M300 Cable Separating and Insulating films 0.00300″ (76µ) Polyester
film
Core Wrap & Separator Tape
Slit film which wraps and binds conductors, separating them from
cable fillers and jacketing materials.
PET (Polyester) Film
In the cable industry films are used particularly suitable for
shielding electrical conductor, as a separating and insulating
films or moisturizing protection. Thus, polyester films, because of
their physical and chemical properties both in data and
communication cables as well as power cables used.
The high tensile strength, low weight per unit area, a high degree
of flexibility and good electrical properties are important
criteria for the selection of the film set in the cable production.
Construction
Single or multi-layer films (polyester, polyethylene, or polyimide)
or aramid paper with optional colored or adhesive coatings or
films.
General Features/Benefits
- Protect conductors from penetration of moisture, chemicals, and
jacket compound
- Maintain cable concentricity and firmness of conductor bundles
- Isolate pairs
- Provide dielectric insulation

Electrical characteristics:
Temperature resistance of 180 ° c, with high mechanical strength,
excellent insulation shielding property, high temperature
resistance, low temperature resistance, is an ideal wrapping
material, mainly used as insulation and isolation, as well as
increased impedance.
Packaging and Marking:
Polyester Tape will be packed in wooden barrel with PE film bag and bubble paper
inside. It is then sealed and inserted in a wooden case. After it
is fixed, an external plastic coversheet is wrapped around it to
avoid water penetration.
Storage:
Polyester Tape has a shelf life of 12 months from production date
if stored in unopened original packages, under dry and clean
conditions at temperatures between 10-30°C. The product will be
damaged if it is stored in a moist area or if it gets in contact
with water.
