Polyethylene Terephthalate (PET) vs Polyether Ether Ketone (PEEK) Anti-static and ESD Plastic Products: Which Material Wins in textile and garment?

2026-09-26 Plastic News 4 views

Polyethylene Terephthalate (PET) and Polyether Ether Ketone (PEEK) are the two most quoted options for anti-static and ESD plastic products in textile and garment projects. Both are widely available, but they behave very differently once they are in service.

This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.

Product Overview

This category covers a family of products rather than a single item. In practice a buyer defines anti-static and ESD plastic products by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include surface resistivity 10^6 to 10^9 ohm/sq; transparent conductive coatings; carbon filled and permanent antistat grades. Materials most often specified are Polyethylene Terephthalate, Polycarbonate, Acrylonitrile Butadiene Styrene, Polyether Ether Ketone, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the textile and garment sector the decision is usually driven by flexibility and abrasion resistance, with colour fastness as a secondary requirement. Typical end uses include elastic tapes, fibre and filament, zipper components.

Key Material Properties

Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.

MaterialDensityTensile strengthService temperature
Polycarbonate1.20 g/cm³55-70 MPa-40°C to 120°C
Polyether Ether Ketone1.32 g/cm³90-100 MPa-50°C to 250°C
Polyethylene Terephthalate1.35-1.40 g/cm³50-70 MPa-40°C to 70°C

Polyethylene Terephthalate is frequently the default selection here: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.

Polyethylene Terephthalate Compared With Polyether Ether Ketone

Polyethylene Terephthalate grades offer excellent barrier to CO2 and moisture, while Polyether Ether Ketone brings retains strength at 250°C. For textile and garment service the difference shows up in chemical resistance and in the long term behaviour under load.

  • Polyethylene Terephthalate: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.
  • Polyether Ether Ketone: PEEK replaces metal in the hottest and most chemically aggressive service conditions.

The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.

Common Grades and Variants

  • Polyethylene Terephthalate based: excellent barrier to CO2 and moisture
  • Polyvinyl Chloride based: inherently flame retardant
  • Polypropylene based: lowest density among commodity plastics
  • Polyether Ether Ketone based: retains strength at 250°C

Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.

Processing and Finishing Options

Processing method drives both cost and performance, so it should be fixed early in the design.

  • Compounding with conductive additive
  • Injection moulding
  • Extrusion
  • Coating

Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.

How to Specify Anti-static and esd plastic products Correctly

Work through these points in order and most specification mistakes disappear.

  1. specify surface and volume resistivity separately
  2. re-test resistivity after cleaning
  3. check the cleanliness requirement for cleanroom use
  4. confirm whether permanent or topical antistat
  5. ground the workstation, not just the plastic

Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.

Frequently Asked Questions

Can you produce anti-static and ESD plastic products in Polyethylene Terephthalate?

Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.

How long does tooling and sampling take?

A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.

What is the minimum order quantity for anti-static and ESD plastic products?

For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.

Do you offer samples?

Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.

What tolerance can be achieved?

Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.

Conclusion

If you are planning a new textile and garment project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
