Corrosion-Resistant Plastics for Industrial Applications

Engineered to Perform in Chemical and Harsh Industrial Environments

Corrosion can significantly reduce the lifespan of industrial components, especially in environments exposed to chemicals, moisture, and temperature fluctuations. Material degradation under these conditions often leads to equipment failure, increased maintenance, and operational disruptions.

Corrosion-resistant plastics provide a reliable alternative. They maintain structural integrity and dimensional stability while performing consistently in chemically aggressive environments.

Johnston Industrial Plastics Limited supplies a range of corrosion-resistant plastics designed to support demanding industrial applications across Canada.

What Makes Plastics Corrosion-Resistant?

Corrosion-resistant plastics are engineered to resist degradation when exposed to acids, alkalis, solvents, and moisture. Unlike metals, they do not rust or oxidize, making them suitable for long-term use in harsh environments.

Key performance characteristics include:

• Resistance to chemical attack
• Low moisture absorption
• Stability in humid and wet environments
• Non-reactive surface properties
• Consistent performance across temperature variations

These properties make corrosion-resistant plastics suitable for both structural and fluid-handling applications.

Types of Corrosion-Resistant Plastics Available

Johnston Industrial Plastics Limited offers several corrosion-resistant materials, each suited to different operating conditions.

1. CPVC (Chlorinated Polyvinyl Chloride): Suitable for higher temperature applications and offers strong resistance to acids and corrosive chemicals. Commonly used in chemical processing systems.
2. Polypropylene: Provides excellent chemical resistance and low moisture absorption. Performs well in environments with acids, alkalis, and salts. Commonly used in tanks, piping, and fabricated components.
3. PTFE (Polytetrafluoroethylene): Highly inert and resistant to nearly all chemicals. Its low-friction properties make it suitable for sealing, lining, and high-purity applications.
4. PVC (Polyvinyl Chloride): Offers strong corrosion resistance and good mechanical strength. Commonly used in electrical and chemical environments. Easily fabricated and welded for custom applications.
5. Polyurethane: Combines corrosion resistance with abrasion resistance. Suitable for applications involving wear and impact.

Where Corrosion-Resistant Plastics Are Used

Corrosion-resistant plastics are used in industries where material durability is critical to operational reliability.

Common applications include:

• Chemical processing equipment
• Water and wastewater systems
• Storage tanks and containment systems
• Electrical insulation components
• Piping, valves, and fittings
• Manufacturing and processing environments

These materials help reduce downtime and extend the service life of equipment in challenging conditions.

Why Choose Corrosion-Resistant Plastics

Compared to traditional materials like metals, corrosion-resistant plastics offer several operational advantages:

• No rust or oxidation
• Lower maintenance requirements
• Lightweight and easier to handle
• Resistance to a wide range of chemicals
• Long service life in aggressive environments

These benefits contribute to more predictable performance and reduced lifecycle costs.
