Features & Benefits
Few competing materials can match the power and versatility of Proxima® thermoset resins. Compared with traditional resins like epoxies, vinyl esters, and polyester resins, Proxima resins exhibit significantly improved performance characteristics without the need for costly capital investments as they were designed to be compatible with today’s industry-standard manufacturing processes.
Proxima thermosets are unique, exhibiting the high performance characteristics of existing systems while minimizing the drawbacks inherent in most of competing materials. Proxima resin systems have the heat tolerance and processability of a thermoset, the excellent impact strength and damage tolerance of a thermoplastic, and the low moisture absorption and corrosion resistance of a fluoropolymer.
Common Properties of Our Multi-Purpose Formulation
Proxima resins can be formulated for a wide variety of application and business requirements.

* Typical values are intended for reference purposes only and should not be used as design specifications. Specific geometry and processing parameters can affect polymer properties.
** Shrinkage in X, Y, and Z axis varies with part thickness: 0.009”/” up to 0.250”, 0.010”/” for 0.250” - 0.375” and 0.011”/” for > 0.375”. Shrinkage through the wall thickness of the part is 0.035”/”.
Property Ranges Throughout the Resin Series
Unlike most thermoset resins, Proxima is not brittle, but exceptionally tough and durable, and has other beneficial characteristics such as corrosion resistance, ease of fabrication, and a wide use-temperature range. We have a variety of formulations to provide excellent combinations of stiffness, impact strength, and heat deflection temperature.
