Mylar® DuPont & 2LSO polyester insulating tubes, tubing, sleeve & insulator caps
THEMAL CLASS B-F
Mylar® DuPont polyester spiral wound tubes & caps produced by Politubes are used for many applications such as electrical insulation, thermal or chemical protection in the electromechanical and automotive industry.
The spiraling technique consists in coupling a series of adhesive-coated strips, winding them around a mandrel, obtaining a tubular whose electrical, thermal and mechanical characteristics are the sum of the ones of each layer.
Mylar® DuPont polyester is an exceptionally strong, durable, transparent film with high tensile, tear and impact strength. It is moisture and vapour resistant and does not transmit oils, greases and volatile aromatics.
These custom designed Mylar® components can be supplied as tubes (round / oval) or ultrasonic welded, ultrasonic dot welded, bullnose insulation caps or low shrinkage semi caps.
Heat shrinkable Mylar ® polyester – 2LSO tubes & insulation caps.
Mylar® polyester tubes and caps can be supplied also with a shrinkage of 35% and they offer a dielectric strength far exceeding other shrinkable materials.
They are extremely tough and forms an excellent mechanical, thermal, electrical, chemical barrier for those components on which they are heat shrink achieving a perfect adhesion and shape of the internal component.
One of the advantages to using a shrinkable polyester film for insulating material is that even after it has been shrunk onto a component, it is able to move, twisting and bending as necessary without exposing the insulated product. This elasticity, coupled with its high temperature rating makes it an ideal product of choice for cable, wire assemblies and crimping.
For special applications also low shrinkage (15%) 2LSO polyester tubes and insulator caps are available.
Politubes adhesives, carefully selected during our forty years of experience, comply with all REACH and RoHS most updated regulations. They are compatible with resins and chemicals in the end-use application and guarantee that the original thermal, dielectric, mechanical, chemical properties of the films used are fully maintained.
Mylar ® tubes & caps are mainly used for:
- Electrical insulation during the crimping of connections and wiring loom
- SPM BLDC brushless motors to fix and protect permanent magnets
- Noise reduction and protection for rotors of universal motors
- Motor lead termination
- Welding insulator
- Electrical connections in automotive market
- Final connections electric motors
- Hermetic electric motors
- Coil windings
- Guarantees the double electrical insulation requested by IEC 60335-1 standard
- Anti-corrosion cathodic protection for flanges bolts
- Hermetic pumps
- Industrial sensors
- Pencil coil
- Transformer tie rods
- Thermistors, thermostats, thermal protectors, thermal switches, thermal cut-off within electric motor windings temperature probe
- Cable harness
