Mylar Rolls
In order to cater for a wider customer base and to keep delivery times to a minimum, Advanced Seals & Gaskets Ltd buy in bulk and hold master rolls of material in stock ready to despatch or convert. One material group available we supply are those used for electrical insulation applications, some of which are manufactured in rolls in the form of papers, resins, laminates and plastics.
Mylar is just one of these materials, also known by the names BoPET (Biaxially-oriented polyethylene terephthalate), Mylar Electrical Insulation Melinex and Hostaphan which is a polyester film made from stretched polyethylene terephthalate (PET). Mylar Electrical insulation films are very thin and are measured in microns instead of mm like other plastics and are available in a choice of 12 to 500 microns and are manufactured in roll form at 914mm wide and in lengths of 25 meters up to 200 meters depending on thickness.
These rolls of material can can be laminated with a choice of adhesive coatings or foils prior to being converted into finished products such as pads gaskets or washers, using methods such as die-cutting or thermoforming, alternatively they can be cut using a slitter or log cutter, producing coils or strips of film or tape. This versatile plastic film can be found used in a variety of general purpose industrial applications within engineering, chemical and electrical industries in the form of one of the components listed above.

What are Mylar Rolls?
Mylar rolls are continuous lengths of material, which are often manufactured in this form where they can be easily transported and held in stock before being cut and supplied as sheets or finished cut components. Materials are sometimes taken in roll form as they give the customer and end user the flexibility to be able to cut their own components as and when required. Mylar is a milky white coloured heat resistant polyester film, which is a flexible film which offers dielectric strength and moisture and chemical resistance (apart from alcohol) which will not become brittle under normal use. Components cut from rolls of Mylar material are durable and versatile, found used in many general purpose applications, including those at high temperatures.
Advantages of Using Mylar
Mylar rolls are a popular multi purpose electrical insulation product which offers a number of excellent properties making it suitable for use in printing, packaging, sealing and electrical applications. Just some of Mylars extensive list of desirable features include its resistance to moisture and many chemicals, it has a broad operating temperature range of -70°C to +150°C, will seal against gases and is generally strong, flexible, durable and long lasting. Mylar electrical insulation can be manufactured in a number of thicknesses from 23 to 500 microns, in roll sizes of between 25 and 200 metres and in different grades including a fairly new flame retardant variant. Mylar electrical insulation has a rough surface which helps with handing, conversion and to hold adhesives prior to converting. Rolls of Mylar Electrical Insulation can be supplied in full, cut and supplied as sheets or converted into pads, gaskets, washers and strips, all available in a plain or self-adhesive finish. Some popular uses for Mylar Electrical Insulation include cable insulations, heating elements, within solar panels, motors and aerospace.
Why use Mylar Rolls?
Products cut from Mylar rolls can be found utilised in an array of applications such as within the magnetic media, imaging and graphics, and packaging markets, however it is more often found within electronic and electrical applications as insulation. Mylar electrical insulation materials offer good ageing properties, are strong and flexible with a high tensile strength, flexibility, durability as well as dimensional stability.
Both the materials and components cut from Mylar rolls of raw materials also demonstrate low moisture absorption, good dielectric properties and high thermal resistance, withstanding a temperature range of -70°C to +150°C. Mylar electrical insulation can be supplied in full sized rolls, which depending on thickness (gauge) are available from 25 linear metres up to 200 metres long x 914mm wide and in thicknesses from 23 to 500 microns, all of which can be used to convert into finished components and products.

Types of Electrical Insulation Materials Available
Some of our other popular electrical insulation materials include:
Epoxy Glass - a green coloured material with good mechanical strength, good chemical, electrical and radiation resistance, low moisture absorption and a working temperature range of upto +120℃.
Kapton - is a polyamide film which offers a combination of mechanical and tear strength along with chemical, electrical and thermal properties that enables the gasket to withstand vibration and extreme temperatures in demanding environments.
Leatheroid - is a grey/blue coloured paper gasket material, also sometimes called Elephantide. This material is used within the electrical industry to insulate hot elements.
MICA - is a mineral based sheeting material which has excellent mechanical performances, is resistant to chemicals and provides electrical and therm insulation. MICA gaskets are often used to replace asbestos as they can withstand extremely high temperatures of up to 1000℃.
Nomex can be manufactured using nomex paper or nomex board, it can withstand high temperatures, has high mechanical and dielectric strength, and is an excellent insulation material for all kinds of electrical equipment and applications.
Presspahn is a brown coloured material, manufactured using kraft wood pulp. Presspahn sheets have excellent physical and mechanical properties, generally used as electrical insulation.
SRBF is resin bonded fibre material which is tough and rigid, with an operating temperature of 120℃, low water absorption and is resistant to wear, impact chemicals.
SRBP (synthetic resin bonded paper) is manufactured using layers of paper and synthetic resins. This material is suited to high and medium voltage application. SRBP has good mechanical and excellent electrical insulation properties, with low water absorption.
