Hybrid Resins

Hybrid Resins

Hybrids are normally cold blends of polyesters (PE), vinyl esters (VE), and even polyurethanes or epoxies that achieve the optimal set of properties for a product. The ability to custom blend resins and various reinforcements affords the ability to optimize the properties very specifically.

Hybrids are very compatible with glass fibers and, depending on the blends, it’s possible to enhance the bondability with other reinforcements like carbon and even aramids.

Best Processes

Open Molding (Hand Lay-up/Spray-up), SMC/BMC, RTM. The best process for your product is a function of your tooling budget, part specification (such as dimensional tolerance and physical properties) and production volume.

Reinforcements

Typically glass, but carbon fiber is an emerging trend.

Special Design Considerations

MFG’s dedicated design experts are available to help with your product design.  MFG’s Technical Design Guide for FRP Composite Products and Parts provides in-depth information for product designers. You can download it on the bottom of this page.

Technical Details

Properties are very similar to polyester, vinyl ester, epoxy and polyurethane as described in those sections. Given the range of blending, properties can be highly tailored to your targets.

The strength-weight ratio is very impressive in comparison to metal because of the low starting density of 1.1 grams/cc for the resin alone.

Cost Considerations

In some cases shelf life (how long the mixture can be stored) may be a factor, as well as blending costs. MFG can tailor properties specifically for your application. Our dedicated R&D Center is staffed with professionals with decades of formulating expertise to help you.
