Industrial Composites for the Corrosion Industry – The Two Main Components

Industrial composites pave the way for the corrosion industry to operate efficiently, and Composites One is proud to be the leading provider of composite material.


To keep up with the high demand of the corrosion industry, our industrial composites must be able to withstand the harsh environmental elements and chemicals often used in conjunction with these materials. That is why we turn to the two most prominently used industrial composites: polyester resin and vinyl ester resin. These two materials are chemical resistant and temperature resistant, making them an ideal solution for the corrosion and energy industry.

The Role of Polyester Resin in Industrial Composites

Polyester resin is the backbone of industrial composites. Typically used in its unsaturated form, UPR (unsaturated polyester resin) is resistant to water, temperature and harsh chemicals found in the corrosion and energy industries. This industrial composite material is highly versatile, having the ability to transition from liquid to solid state under the correct conditions.


Many advantages are associated with using polyester resin as an industrial composite for the corrosion industry, such as:


  • Water resistance and chemical resistance
  • Temperature resistance typically up to 80°C
  • Cost effective, especially when Orthophthalic resin is used
  • Limited thermal expansion
  • Resistant to corrosion and weathering over time


Because of these advantages, polyester resin is the backbone of the industrial composites industry.

The Role of Vinyl Ester Resin in Industrial Composites

Vinyl ester resin is a median between polyester resin and epoxy. Though commonly used in conjunction with polyester resins, vinyl ester resins have a higher resistance to corrosion, chemicals and environmental elements than polyester resins. To ensure the best industrial composites are used in the corrosion industry, vinyl ester resins are often blended with polyester resins to create the most durable and resistant composite available for these industries. As an added bonus, vinyl ester resin increases the strength of polyester resin, making it more resistant to corrosion over time.


Halogenated vinyl esters and polyester resins provide manufacturers with the opportunity to develop fire retardant composite products. Halogenated fire retardant (FR) resins are generally better performing, less expensive, easier to process and have better physical properties than halogen-free formulations. The type of fire retardant resin solution used will depend on the application and specific fire performance requirements. Uses can include electrical and electronic components, building panels, ducting, roofing, and other equipment exposed to high temperatures.
