Neoprene Seals

Neoprene seals are a versatile and cost-effective choice for a wide range of industries. They offer a balance of performance and affordability, making them ideal for many sealing applications.

What are Neoprene seals?

Neoprene seals are mouldings formed from polychloroprene, a synthetic rubber known for its durability and flexibility. These seals create a tight barrier between surfaces, preventing leaks and protecting components from contaminants.

What are some common Neoprene applications?

Neoprene’s versatility extends across various industries, including:

  • Aerospace: Sealing environmental control systems.
  • Energy: Sealing valves, pipes, and flanges in power generation facilities.
  • Food & Beverage: Food-grade neoprene seals for processing equipment and packaging.
  • Instrumentation & Electronics: Protecting sensitive components from dust, moisture, and vibration.
  • Motorsport: High-performance seals for suspension systems.
  • Subsea & Oil & Gas: Durable seals for demanding underwater environments, resisting oil and gas exposure.

Fibre-optic Cable Connectors
These Fibre-optic Cable Connectors combine highly detailed cross-sections along with rubber to metal bonding. Designed to work in the harshest of conditions they are used primarily in subsea applications.

Neoprene Characteristics

Neoprene provides almost unique environmental performance. Here’s an overview of it’s properties:

  • Hardness: Ranges from soft and flexible to firm for various sealing pressures.
  • Tensile Strength: High resistance to pulling forces, ensuring a strong seal.
  • Tear Resistance: Resists punctures and rips for long-lasting performance.
  • Impact Resistance: Absorbs shock and impact without cracking.
  • Compression Set: Excellent mechanical performance maintaining shape and sealing integrity under compression.
  • Temperature Resistance: Performs well in moderate temperatures, with options for low and high-temperature applications.
  • Weather and Sunlight: Good resistance to weathering and sunlight degradation.
  • Water Resistance: Excellent for applications involving water exposure.
  • Abrasion Resistance: Moderate resistance to wear and tear.
  • Solvent Resistance: Limited resistance to certain solvents, requiring careful selection.
  • Oils and Gasoline: Resists some oils and gasoline, but compatibility testing is crucial.
  • Adhesion to Metals: Bonds well with many metals using bonding agents or adhesives.
