Polyurethane O-Rings - Benefits, Properties and Varieties

An O-ring is also known as a toric joint which is designed in a manner so that it can be used to assemble two or more parts. It acts as a seal between the parts. O-ring manufacturers design it to be used in dynamic applications or in static applications. Polyurethane O-rings are specially suited to handle dynamic loads. They are applied in pneumatics, hydraulics and in other critical areas. Their high mechanical strengths make them superior as compared to the other o-rings.

Benefits:  Polyurethane o-rings are long-lasting, strong and durable and are thus best suited for industrial applications.

1. The structural bonds of these products are incredibly good and also offer flexibility.
2. They can be customized for several applications.
3. Twisted polyurethane o-rings can be excellently applied in transfer belts, line shaft conveyors and roller to roller conveyors.
4. The loop and hook system in these o-rings make them easy to use.
5. This variety of urethane o-rings offer shortcut in connection and thus there is no need to break up the conveyor system.

Properties: Check out some of the unique features of polyurethane o-ring material:

1. Flexibility and Hardness: Owing to the hardness of this material, it can withstand any amount of load. Another significant property of polyurethane is that it can be molded to any shape before put to use.
2. Versatility: Polyurethane offers excellent insulation and can perform in any differences of temperature, humidity and electricity.
3. Cost Effective: The manufacturing cost of polyurethane is much cheaper as compared to plastic. Therefore, it is available at a much lower cost in the market.
4. Sterility: Polyurethane is resistant to various fungi like mold and mildew. Thus, there are no issues of food contamination when these materials are used.

Types of Polyurethane:  This type of o-ring is available in different types and each one of them has their individual advantages and applications. Polyester is one of the most common types of polyurethane. It is resistant to hydrocarbon oils and hydraulic oils which offer great application at lower temperatures.

Another type is poly-caprolactone. This variety of polyurethane o-ring is also resistant to oil.

So, for faster and smoother conveyor, you can always rely on polyurethane o-rings.
