PET Rod – Strong, Reliable, and Built for Precision

PET rod is a fantastic option if you're looking for a rigid, wear-resistant plastic that holds its shape. Polyethylene Terephthalate, PET is a high-performance engineering plastic known for its strength, stability, and smooth machinability. Whether you're working on gears, bearings, conveyor parts, or food-safe equipment, PET offers long-lasting durability with minimal maintenance.

One of its standout features is that it absorbs very little moisture, meaning it won't swell or change shape over time. This makes it perfect for applications that require precision and consistency, especially in humid or wet environments.

​

What Makes PET Rod a Great Choice?

Strong and Rigid
PET is naturally tough, making it a great alternative to metal in applications requiring high strength without the extra weight. It resists deformation under pressure, so parts made from PET hold up well, even in high-stress environments.

​

Keeps Its Shape – Even in Humid Conditions
Some plastics can absorb moisture and swell, which can throw off measurements and cause issues over time. PET doesn’t have this problem—it stays dimensionally stable, meaning it holds its exact shape even in humid or wet environments.

​

Low Friction - Smooth, Long-Lasting Parts
PET has a naturally low friction coefficient, meaning parts slide smoothly and don’t wear down quickly. This makes it an excellent choice for moving components that must last a long time, such as gears, bushings, and conveyor rollers.

​

Handles Chemicals with Ease
PET resists oils, acids, cleaning agents, and industrial chemicals, so it’s commonly used in food processing equipment, conveyor systems, and machine parts that need to be cleaned regularly without breaking down.

​

Food-Safe and Hygienic
PET is FDA-approved for food contact, meaning it’s safe to use in food processing, beverage production, and packaging applications. It doesn’t absorb bacteria, odours, or moisture, making it a hygienic choice for cutting boards, conveyor belts, and food-handling surfaces.

​

Easy to Machine with High Precision
PET is easy to cut, drill, and shape, making it a favourite among manufacturers, engineers, and machinists. It also holds tight tolerances, making it an excellent choice for applications that require precision and consistency.

​

Where Is PET Rod Used?

Because of its strength, low friction, and stability, PET rod is widely used across many industries, including:

​

Gears and Bearings - Smooth operation and long-lasting durability make PET perfect for moving parts.
Bushings and Seals - PET maintains its shape and wear resistance, ensuring a long service life.
Food Processing Equipment - Safe for direct food contact, PET is used in conveyor belts, cutting surfaces, and machine components.
Conveyor Components - PET’s low friction and wear resistance are ideal for rollers, guides, and chain links.
Medical and Pharmaceutical Equipment - PET is used in surgical and sterilised equipment because it withstands cleaning and high-precision machining.
Electrical Insulation - PET, due to its strong insulating properties, is used in cable insulation, electrical housings, and circuit components.
Automotive and Aerospace Parts - PET is strong yet lightweight, making it useful for precision-engineered automotive and aerospace components.

Available Sizes and Colours

PET rods come in various diameters and lengths so that you can find the right size for your project. The most common colours are natural (white) and black, though some suppliers may offer custom colours. If you need a specific size, many suppliers also provide cut-to-size options to match your exact requirements.
