What Different Types of Silicone Gaskets Are There


Nearly all manufacturing companies have uses for silicone gaskets due to silicone being extremely versatile. Silicone and silicone-based gaskets commonly have many wished for qualities, including great resiliency and heat resistance. They come available as moulded gaskets, and foam or sponge gaskets, plus in shapes cut from solid silicone substance.

A number of manufacturers produce specialty gaskets from various materials, like gel-based silicone or silicone which has been moulded with metal, for specialised industrial treatments. Some of the unique businesses that make use of gaskets developed from silicone include the likes of food and medical organisations, aero – and vehicle based businesses, and manufacturers of electronics.

Made by Different Methods

Gasket manufacturers normally make silicone gaskets in different types of methods.

  1. They utilise die-cut or water jet apparatus to cut solid gasket material to develop solid gaskets.
  2. Sponge and foam gaskets are much the same, but a different material is used.
  3. The last process makes use of mould injection techniques. Companies will order the type of gasket that best suits their requirements, such as utilising foam gaskets for vibration reducing seals and various other sealing products in Leeds.

Solid Silicone Gaskets are the Strongest Kind of Gasket

  • Even though a lot of gasket manufacturers cut solid gaskets from large sheets of solid silicone, a number of them utilise injection or compression moulding techniques.
  • Nowadays, silicone gasket sheeting is available for anyone who wishes to customise their own gaskets.

Various Grades

  • The sponge range of gaskets can vary from soft to firm.
  • The firm type of sponge gasket material is akin to the soft grade of solid gasket material.
  • The sponge silicone gasket material is closed cell, and known as expanded silicone rubber.
  • Manufacturers provide foam gasket material as closed or open cell.
  • The open cell gaskets are efficient as dust-proof seals.

A number of applications require specialised silicone gaskets.

  • Silicone gaskets that contains metal are frequently used to make electrical conductivity.
  • Interchangeably, silicone, combined with other types of materials, like ceramic powders, are put to use to disperse with heat in electrical devices without creating and conductivity.
  • All are perfect examples of silicone’s diverse versatility.

Yet Even More Qualities

  • Superb resistance to aging and weakness
  • Is able to withstand solar and ozone degeneration
  • Is resistant to constant compression

The gel-based silicone easily adjusts to all surfaces, and a number of electronics manufacturers make use of them as thermal interface seals.

  • Its flame-resistant capability makes certain that it’s useful in a range of applications, including demonstrative apparatus.
  • When silicone is burned it is normally non-toxic, and the ash still keeps its electrical insulation ability.


Businesses, typically utilise food-grade silicone gaskets as seals in areas such as:

  • Water purification
  • Filtration
  • Oven
  • Refrigeration
  • Food-manufacturing

Other gasket uses include external electrical appliances due to its insulating capability. Buyers can purchase silicone gaskets in different colours, making it an advantage over traditional natural rubber.
