Welcome to Know Mylar Sleeve

Mylar sleeve is the most recognised and industry approved sleeve material. It is the preferred material for bolt isolation as It provides excellent resistance against galvanic corrosion.

Is Mylar® the Same as Polyester?

The answer is Yes. Mylar® is the brand names of polyester film created by DuPont Teijin Films.

Mylar® 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. It was first developed in the mid-1950s by DuPont.


Mylar sleeve has excellent temperature resistance, strong tear initiation and puncture resistance. It also has superior chemical resistance, excellent oil, grease or moisture-barrier resistance.


Mylar sleeve is suitable for general electrical insulator applications, bolts protection, as it has excellent dielectric strength and low water absorbtion. It is also used for many applications such as electrical insulation, thermal or chemical protection in the electromechanical and automotive industry.
