Chemical Compatibility Lookup

Polymers used in the oil and gas industry endure some of the most brutal conditions on the planet. Climates range from sweltering desert to arctic freeze—and that’s not even the worst part. High-performance polymers face their biggest challenge inside, within the wells and machinery.

From pipelines to seals, engineers rely on polymers for their ability to hold up under duress. Designed to withstand high temperatures and tremendous pressure, many of these compounds can take an incredible beating. But even high-performance polymers aren’t immune to chemical reaction.

Each polymer is formulated to have specific strengths, such as heat, light and chemical resistance. But most also have a chemical Achilles heel. Exposure to the wrong substance can change a polymer’s properties enough that it can’t do its job. Sealing capability or structural integrity is compromised as the material shrinks, swells, hardens, cracks or tears.

To prevent premature failure, it’s crucial to understand the chemical compatibilities of polymers before selecting the right one for your application.

Understanding Chemical Compatibility

A polymer is a long, chainlike molecule consisting of several thousand chemical repeating units linked together by covalent bonds. Its useful properties stem from its size, which is very large on a molecular scale.

Under normal conditions, a polymer’s long molecular strands are coiled up like spaghetti. When force is applied, the molecules straighten out. When released, they bounce back to their compact, random tangle. That’s what gives polymeric compounds their flexibility and toughness.

Exposure to certain chemicals can break the bonds that link together a polymeric chain, causing the strands to become shorter. Since a polymer’s usefulness relies on its molecular size, any loss in chain length lowers its tensile strength and can cause premature cracking or other failure.

That’s why, when you’re working with polymers such as urethane, rubber or plastic, chemical compatibility plays a big role in selecting which material is right for the job.

Types of Industrial Polymers

High-performance polymers are engineered to retain their mechanical properties and insulating abilities even as they age. When they fail, it’s often because of environmental factors such as chemical exposure.

Since each application requires a specific type of performance under certain conditions, each polymer is engineered with different chemical resistances. A material’s weakness depends on its molecular makeup. There are three main types of industrial polymers:

Plastic: Although it’s more flexible than wood or metal, plastic is the most brittle of the commonly used polymers. The harder it is, the more likely it will crack and break. Stretch it beyond a certain point, and it will stay permanently stretched.

Rubber: Polymers with elastic properties, such as rubber, are known as elastomers. Rubber is able to stretch much farther than plastic and still return to its original shape. It can stretch, compress and rebound while still providing shock insulation.

Urethane: With the flexibility of rubber and the cut and tear resistance of plastic, polyurethane is capable of tremendous impact resistance. It can withstand substantial stretching and still return to its original form. Still, even with urethane, chemical compatibility remains an issue.

Each type of polymer has its own characteristic modes of degradation as well as heat, light and chemical resistances. When selecting an application-specific plastic, urethane or rubber, chemical compatibility should always remain top of mind.
