BEIGE POLYPROPYLENE ROD

Polypropylene Rod is a strong choice where you need a lightweight, moisture-resistant and chemically resistant engineering plastic.

It is particularly useful for chemical-handling components, wet-environment parts, spacers, bushes, guides, rollers, fittings and general machined components.

Polypropylene is less rigid than engineering plastics such as Acetal and has relatively high thermal expansion. Where high stiffness or very close dimensional tolerances are the main requirement, another material may be a better choice.

• Excellent chemical resistance — useful in many acid, alkali and chemical-handling environments.
• Very low moisture absorption — suitable for wet and moisture-exposed applications.
• Lightweight — polypropylene has a low density compared with many other engineering plastics.
• Corrosion resistant — will not rust or corrode like metal.
• Useful electrical insulation for suitable industrial applications.
• Machinable using conventional equipment and appropriate sharp tooling.
• Economical for many general-purpose engineering components.

Beige Polypropylene Rod is commonly machined into:

• Spacers
• Bushes and bushings
• Guides
• Rollers
• Valve components
• Chemical-resistant fittings
• Washers and supports
• Jigs and fixtures
• Wet-environment components
• General industrial machined parts

Polypropylene is well known for strong resistance to many acids, alkalis and other chemicals, which makes it useful in chemical, process and wet-environment applications.

Chemical compatibility depends on the exact chemical, concentration, temperature, exposure time and mechanical loading.

Where chemical exposure is critical, suitability should be confirmed for the specific operating environment before selecting the material.

Polypropylene absorbs very little moisture, so it is useful in wet, wash-down and liquid-handling environments.

Unlike moisture-sensitive plastics, its low water absorption helps minimise dimensional changes caused specifically by water uptake.

Temperature changes can still cause dimensional movement because polypropylene has relatively high thermal expansion.

Polypropylene can be turned, milled, drilled and bored using conventional machining equipment and suitable sharp tooling.

Sharp tools, positive cutting geometry and good chip clearance help minimise heat build-up and improve surface finish.

Because polypropylene is relatively flexible and expands more with temperature than materials such as Acetal, careful machining is important where dimensional accuracy is required.

All Warlond Plastics Beige Polypropylene Rod is supplied in 1000mm lengths. Select your required diameter using the product options above. Custom rod cutting or fabrication is not offered.

Polypropylene is suitable for many normal industrial operating temperatures but should not be treated as a high-temperature engineering plastic.

Its stiffness and dimensional behaviour can change as temperature increases, and polypropylene also has relatively high thermal expansion.

Where elevated temperature is a major requirement, the load, service duration and operating environment should be considered before selecting the material.

Polypropylene as a material family is widely available in grades intended for food-contact applications. However, food-contact compliance depends on the specific resin and supplied grade.

We do not recommend assuming food-contact compliance from the material name alone.

If your application requires FDA, Australian, EU or other food-contact documentation, please contact Warlond Plastics before ordering so the requirements can be checked against the supplied material.

Beige Polypropylene Rod is available in selectable diameters up to 50mm.

All rod is supplied in 1000mm lengths only.

Select the required diameter using the product options above to view current pricing and availability.

Engineering plastic rod is supplied as machining stock. Where a precise finished diameter is required, allow sufficient material for machining to the final dimension.

Polypropylene has a low-energy surface and is generally difficult to bond using ordinary adhesives.

Mechanical fastening or plastic welding may be more suitable for many applications.

Specialised surface treatments, primers and adhesive systems can sometimes be used, but the bonding process should be tested before relying on an adhesive joint.

Polypropylene is a good economical choice for chemical, moisture-resistant and lightweight components, but another engineering plastic may perform better where the requirements are different.
