Plastic Gaskets: Cut to Your Drawing from Engineering Plastics
Reliable, Customisable, and Delivered Fast by Hollinbrow Precision Products
Hollinbrow manufactures plastic gaskets cut to your drawing in PTFE, nylon, polypropylene, polyester, PEEK and other engineering plastics, from single prototypes to production runs. A plastic gasket seals the joint between two surfaces where rubber or fibre would absorb moisture, react with the media or break down, giving you chemical resistance, electrical insulation and a stable, low-friction seal. They are part of our wider custom gasket range, cut at our UK site.
Why Choose Plastic Gaskets?
Plastic gaskets resist many chemicals, absorb little or no moisture, insulate electrically and, in materials such as PTFE and acetal, give low friction. Compared with a rubber gasket, plastic is firmer and compresses less, so it suits thin, precise seals, spacers and insulating washers. Where you need a softer, more compressible seal, a rubber gasket is usually the better choice, and we can advise on which suits your joint.
Plastics We Offer for Plastic Gaskets
- Polyester (PET / Mylar®) – One of the most common plastic shim materials. Good dimensional stability, strength and electrical insulation. Available in very thin gauges for thin gaskets and insulating washers.
- Polycarbonate (PC / Lexan®) – Tough, impact-resistant and dimensionally stable. Useful where greater durability is required.
- Polypropylene (PP) – Lightweight with good chemical resistance and low moisture absorption.
- Polyethylene (PE) – Available as LDPE, HDPE and UHMWPE. Good chemical resistance; UHMWPE also offers excellent wear and low friction.
- Acetal (POM / Delrin®) – Strong, rigid and dimensionally stable with low friction. Good for engineering shims, spacers and wear applications.
- Nylon (PA6 / PA66) – Strong and wear-resistant, although it absorbs more moisture than many other engineering plastics.
- PTFE (Teflon®) – Excellent chemical resistance, very low friction and suitable for relatively high temperatures. See our PTFE gasket range.
- PEEK – High-performance engineering plastic with excellent temperature, chemical and mechanical properties. Used particularly in aerospace and demanding industrial applications.
- PVC – Economical with good chemical and electrical properties for general-purpose applications.
- Kapton® (Polyimide) – Very thin, high-temperature film with excellent electrical insulation properties, particularly useful in electronics and aerospace.
How We Make Plastic Gaskets
We cut plastic gaskets from sheet to your drawing, sample or specification using CNC and die-cutting, holding tight tolerances from the first gasket to the last. We can supply rings, flange gaskets, washers and multi-hole shapes in the thickness and material your joint needs.
Applications of Plastic Gaskets
Our plastic shims are trusted by engineers, builders, and manufacturers across the UK and beyond. Typical applications include:
- Chemical processing and pumps: chemical-resistant seals in PTFE, polypropylene and polyethylene
- Electrical and electronics: insulating washers and gaskets in polyester, Kapton® and polycarbonate
- Aerospace: lightweight, non-corrosive gaskets in PEEK and PTFE
- Automotive and general engineering: spacers, wear washers and low-friction gaskets in acetal and nylon

Frequently Asked Questions About Plastic Gaskets
Ready to experience the benefits of Hollinbrow plastic shims? We make it easy to get started:
Can you make plastic gaskets to my drawing?
Yes. Send us your drawing or specification and we will quote for plastic gaskets cut to match.
Which plastic is best for chemical resistance?
PTFE offers excellent chemical resistance, and polypropylene and polyethylene are also widely used. Tell us the media, temperature and pressure and we will recommend a material.
Do you also supply plastic shims?
Yes. If you need a spacer rather than a seal, see our plastic shims.
