Cryogenic Industry Thermoset Composites

Thermoset Composite Parts for the Cryogenics Industry

Cryogenics involves the production, storage, and transportation of materials at ultra-low temperatures—often below -160°C. From liquefied natural gas (LNG) systems to superconducting applications, cryogenic environments demand materials engineered for extreme cold, high performance, and long-term stability.

Thermoset composites maintain strength, dimensional stability, and electrical insulation even in frigid conditions—making them ideal for structural supports, insulators, valve components, and other critical parts in cryogenic systems. Atlas Fibre provides cryogenic equipment manufacturers with precision-machined components and fabrication-ready shapes made from proven thermoset materials. Our composites are built to perform where metals and thermoplastics fall short.

We collaborate with engineers and procurement teams to reduce complexity, contain costs, and deliver reliable materials that perform under pressure—no matter how cold the environment.

Benefits of Cryogenic Compatible Materials

Thermoset composite materials are ideal for use in demanding environments due to their physical and chemical properties.

Low thermal creep materials and cryogenic plastics offer multiple benefits to the industry, including:

Insulation: It’s critical that cryogenic piping and pumps are insulated and protected from the extreme cold. Composite materials offer thermal insulation, safeguarding equipment from below-freezing temperatures. Additionally, composite materials provide excellent electrical insulation.
Weight: Thermoset composites weigh much less than metal. Due to their reduced weight, the materials help to improve costs.
Strength: G10 cryo and other composite materials have a high strength-to-weight ratio. For example, G10, a type of glass epoxy composite, has a tensile strength-to-weight ratio nearly twice that of aluminum. Their strength allows them to perform well as structural elements in cryogenic equipment.

Thermal expansion: Cryogenic grade thermoset composite materials have extremely low thermal expansion and remain stable at low temperatures.
Temperature tolerance: Cryogenic equipment experiences prolonged exposure to subzero temperatures and must withstand extreme cold. Thermoset composites have a high temperature tolerance and can withstand the extreme temperatures of cryogenics.
Corrosion resistance: Corrosion occurs when oxygen gradually destroys materials, weakening metals over time. Thermoset composites resist corrosion. The addition of a resin binder enhances the material’s corrosion resistance.
Flexibility: Atlas Fibre works with each of our customers to create materials and parts that fit their unique designs. We can machine phenolic and glass thermosets as well as thermoplastic for the aerospace industry.

Uses for Cryogenic Composites

Thermoset composites, such as cryogenic grade G10, make up many of the parts used in cryogenic equipment, including:

Piping
Sensors
Pumps
Containers
Valves
Winding insulators
