Description
This high-performance PETP extruded natural rod is a versatile engineering plastic stock material, designed for precision-machined components that demand excellent dimensional stability. Manufactured from polyethylene terephthalate in natural (unfilled) grade, it offers a smooth, consistent finish that is ideal for turning, milling and drilling on both manual and CNC equipment.
With low moisture absorption and good resistance to creep, this PETP rod is particularly suited to applications where tight tolerances, mechanical strength and long-term reliability are essential. Available in a wide choice of diameters and standard lengths, it is commonly used for bearings, bushes, guides, wear parts and structural components in industrial machinery, food-processing equipment and general engineering environments.
Product Features
- Manufactured from high-performance PETP (polyethylene terephthalate) in a natural, unfilled grade for consistent machining behaviour.
- Available diameters from 12 mm, 16 mm, 20 mm, 25 mm and 30 mm, plus a further range of intermediate and larger sizes to suit varied design requirements.
- Supplied in standard lengths of 1000 mm, 2000 mm and 3000 mm to accommodate both small parts and longer components.
- Excellent dimensional stability with low thermal expansion, supporting high-precision machined parts.
- Very low moisture absorption, helping components maintain size and shape even in humid environments.
- Good mechanical strength and stiffness, suitable for load-bearing and wear-resistant engineering applications.
- Smooth surface finish on the extruded rod for improved sliding characteristics and reduced finishing work.
Key Features and Benefits
- Maintains tight tolerances thanks to low moisture uptake and stable material properties, reducing the risk of swelling or warping in service.
- Supports long service life in dynamic applications through good wear resistance and resistance to creep under load.
- Easy to machine with standard metalworking tools, helping to minimise production time and tooling costs.
- Offers a strong combination of rigidity and toughness, allowing designers to reduce component weight without compromising performance.
- Consistent quality across multiple diameters and lengths simplifies repeat production and makes material planning more predictable.
- Versatile stock shape suitable for a wide variety of turned, milled and drilled parts, reducing the need to hold multiple different plastic grades.

Frequently Asked Questions
Can this PETP rod be machined with standard workshop tools?
Yes, the rod is designed for machining using standard metalworking equipment such as lathes, milling machines and drill presses. Sharp tools and appropriate cutting speeds are recommended to achieve the best surface finish and dimensional accuracy.
Is this PETP rod suitable for use in wet or humid environments?
Yes, PETP has low moisture absorption compared with many other engineering plastics, so it maintains its dimensions better in wet or humid conditions. However, it is still good practice to consider drainage, cleaning, and any chemical exposure in the final application.
Can I cut the rod to custom lengths on site?
Yes, the rod can be cut down from the supplied 1000 mm, 2000 mm or 3000 mm lengths using suitable saws or cutting equipment. Ensure the rod is well supported during cutting and allow for a small machining allowance if tight final dimensions are required.
