Plastic Gaskets

Advanced Seals & Gaskets Ltd work with a number of manufacturers and suppliers, therefore able to offer gaskets cut from an array of non-metallic materials including plastics. As our gaskets are produced in-house on state of the art machinery, we can manufacture bespoke items to match our customer’s samples/drawings, from a simple rectangular picture frame gasket to a more complex shape with cut-outs – we can offer a solution. Whether it’s a small sample batch or a multi-thousand run, we have a machine to quickly and accurately produce perfectly formed gaskets in a range of sizes, these include a number of presses and CNC machines. Our gaskets can be produced plain or with a choice of finishes including foils and choice of self-adhesives.


What are Plastic Gaskets?

Gaskets sometimes come in the form of a strip or pad but are generally an intricately cut shaped piece or ring of material placed between two surfaces to create a seal. Plastics are often used to manufacture gaskets as they’re lightweight and one of the preferred alternatives to metal due to their durability and resistance to corrosion, they also come in different grades with a range of qualities for example impact strength, heat and chemical resistance, etc.


Why use Plastic Gaskets?

Plastic gaskets are available in a variety of grades and have a number of properties and can be used as a solution in a number of applications including sealing against fuel, oil and water, gaskets in machinery where exposed to water and gaskets where there is exposure to corrosive fluids.  Industries that utilize plastics gaskets are packaging, petrochemical, oil & gas and petrochemical processing.


Types of Plastic

Advanced Seals & Gaskets work with a multitude of material manufacturers and suppliers, giving our customers more choice when designing their plastic gasket solution, each type has its own range of properties, colours, thicknesses, etc – our most popular materials being:

  • PTFE
  • Polycarbonate
  • Polypropylene
  • HIPS (High Impact Polystyrene)
  • PVC
  • ABS
  • Polyester 
  • Acetal
  • Acrylic
  • Nylatron


Benefits of Using Plastic Gaskets

Using plastic gaskets offers a whole host of benefits, not only are they cheaper and lighter in weight in comparison to metal and some sponge options, but also offer more resistance to wear, abrasion and corrosion (will not rust unlike metal gaskets). Despite being a fairly rigid material, plastic gaskets can still be compressed to create a tight seal and as well as being great for insulation applications as it does not conduct heat or electricity.
