The Proxima® thermosets are a groundbreaking advanced polymer system based on dicyclopentadiene (DCPD), specially formulated to address high performance applications unmatched by many of today’s competing materials technologies. Our thermosets are designed to be a near drop-in replacement for traditional resins, such as epoxy, vinyl ester, and polyester resins, adaptable to industry-standard manufacturing processes.

Proxima Thermosets
Proxima thermosets derive their unique characteristics through a polymerization reaction enabled by Materia’s proprietary Grubbs Catalyst® technology. Enabled by the versatility of our metathesis catalyst portfolio, we can design and develop a wide range of performance polymers with optimal processing and superior properties.

Superior Performance for Next-Generation Materials
At Materia, we develop our own proprietary blends of monomers and functional additives that are polymerized by our Grubbs Catalyst products through a process known as ring-opening metathesis polymerization (ROMP), which creates unique high-performance polymers with the structural integrity of a thermoset and the toughness of a thermoplastic.

Proxima thermosets are designed to deliver the performance characteristics that companies need to solve advanced materials challenges.

  • Excellent Toughness. High-speed impact resistance and crack propagation resistance enable longer lasting parts with more predictable life cycles.
  • Lightweight. Density is “similar to water” and 10-15% lighter than comparable thermoset resins.
  • Excellent Hot/Wet Properties. Extremely low water absorption of polyolefins combined with the thermal stability of thermosets.
  • Low Carbon Footprint. Cradle-to-gate emissions 47% lower than standard epoxy resins.
  • Low Viscosity Resins. Viscosity is also “similar to water”, enabling quicker molding of complex shapes, high filler loadings, and lower void content.

Compatibility with Standard Processing Techniques
Proxima resins are two-part liquid thermosetting systems specially designed to have a low viscosity for fast and easy mold fill or infusion. As a result, Proxima resins can be processed by most standard thermoset processing techniques and are one of the few advanced polymers able to deliver performance properties with effortless integration into today’s manufacturing processes.

Flexible Property Range
The Proxima resin platform enables a range of formulations, from rigid structural polymers to flexible soft materials, and anything in between.
