PVC Electrical Insulation

PVC Electrical Insulation

PVC Electrical Insulation

A small group of products manufactured by ASG cut from various electrical insulation materials, supplied by world leading plastic suppliers and available in numerous grades, colours and thicknesses, one of which includes PVC plastics or Polyvinyl Chloride - recognised as one the most popular engineering plastics.  PVC plastics sheets can be supplied in sizes of up to 2000mm x 1000mm and in thicknesses between 1mm and 20mm as standard from which components such as strips, pads, washers, gaskets and other bespoke shapes seals can be cut. Non-standard shaped and sized products with different textures can also be supplied to order as PVC plastic can also be moulded or vacuumed formed into bespoke shapes and are found used across several industry sectors.  By using customers'  samples, drawings or dimensions and one of our many on-site saws, presses or CNC machines, we are able to convert PVC plastic sheets into parts which can be supplied with a choice of self-adhesives or foils.

    What is PVC Electrical Insulation?

    Polyvinyl chloride or PVC can be manufactured in a range of forms including soft foams, rigid sheets and very thin flexible films making it one of the world's most popular synthetic plastics polymers.  PVC plastic components as lightweight and one of the preferred alternatives to metal due to their durability and resistance to weathering and corrosion,  they are often purchased for use in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities or in this case to act as insulation such as electrical barriers.  PVC plastics are used in the conversion and production of electrical insulation components which include strips or seals for electrical insulation applications as the material ‘binds’ electrons, holding them still and this prevents electrical charges - in return preventing electric shocks, making it perfect for use within circuit board, wire sleeves and trunking, high voltage applications, etc

    Why use PVC Electrical Insulation?

    Plastic materials are each formulated and manufactured using different versions and compositions of compound in order to produce a product with specific and unique properties making PVC electrical insulation stable and inert, extremely workable and will hold their shape during fitting and even vigorous milling and sawing processes.

    It is highly chemically stable and offers excellent compressive strength and electrical insulation properties, available in a range of colours which can be very transparent or opaque.  PVC electrical insulation plastics can be cut and converted into a range of intricate sizes using various techniques including laser cutting, die cutting, sawing and even thermoforming (where the material is heated until it is soft, re-shaped and then left to cool and harden).

    A few of the applications in which PVC electrical insulation components can be found used include, chemical or acid tanks, cladding, electrical cases and within machinery and equipment.  The high dielectric strength of PVC Electrical Insulation provides a barrier restricting the flow of electrical current, protecting electrical conductors from coming into contact with people or tools during installation, repairs or when an electrical appliance or device is being used.

    Benefits of using PVC Electrical Insulation

    • Cost-effective
    • Impact, corrosion, abrasion and weather resistant
    • High chemical resistance
    • Strong and rigid
    • Can be easily machined, heated and bent, glued and moulded
    • low heat and electricity conductivity for use with electrical insulation

    Other Types of Electrical Insulation Materials Available

    Advanced Seals & Gaskets work with a multitude of material manufacturers and suppliers, giving our customers more choice of electrical insulation products - our most popular materials being:

    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 up to +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℃.

    MYLAR is an extremely strong, flexible polyester film.  MYLAR is an excellent insulation material with dielectric strength, moisture resistance and is an excellent insulation material.

    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.

    Valox is an excellent electrical insulation material which also offers flame retardant properties.

    PTFE is a non-conductive plastic material used to produce electrical insulation sheets.  PTFE sheets are suitable for high temperature applications and have a high melting temperature.  This material has excellent dielectric properties and can be often found used in circuit boards.

    Advantages of Using PVC Electrical Insulation

    PVC plastic components are some of the world's most commonly used products, this is due to the vast range of advantages and desirable properties the material and products offer.  The material itself is strong, rigid and lightweight.  PVC electrical insulation plastic offers durability and longevity as PVC plastic is resistant to chemical and weather corrosion, shock and abrasion which means it can be utilised for many indoor and outdoor applications.  PVC can be made available in standard sizes or moulded into bespoke sizes both of which can be converted by way of sawing, milling, drilling, glueing or bending (heated and manipulated) to produce finish components such as washers, strips, gaskets, tubes, pipes, etc.  PVC plastic is non-toxic, do not conduct electricity so can be used for electrical applications and although PVC plastic will burn, it is self-extinguishing due to having a high chlorine content.    Using PVC Electrical Insulation within electrical devices and equipment for the purpose of electrical insulation protects them from generating and passing high voltages, reduces the cost of energy, improves performance and protects users from shock.
