What EFI POLYMERS does

EFI Polymers (legal entity Epoxy Formulations INC) is a privately held, Denver-based polymer formulator and manufacturer founded in 1993 that specializes in epoxy and urethane formulations for electrical potting, motor encapsulation, and adhesive applications. Its core products are two-part epoxy and polyurethane systems ranging from low-viscosity potting compounds (sub-1,000 cps) to high-Tg motor stator encapsulation materials (up to 200°C+ Tg, up to 1.6 W/m-K thermal conductivity), many carrying UL 94V0, UL 1446 Electrical Insulation System, and 120°C RTI certifications. The company also offers custom formulation services, private label and toll manufacturing, and adhesive systems tailored for fast cure, high temperature, and food-contact applications.

EFI serves primarily electronics manufacturers, motor manufacturers, and power-grid component producers, with secondary exposure to private label and toll-manufacturing customers. The company operates a sales-led, technical-account-manager-driven go-to-market model with hands-on application engineering from needs analysis through production scale-up, supported by content marketing (white papers, application guides) and a LinkedIn presence. Revenue is generated through quote-based pricing on custom and standard polymer formulations, with no public pricing and application-specific contracts that may run on multi-year terms. EFI maintains an ISO 9001:2015 certified manufacturing facility in Denver equipped with heated/chilled vessels, vacuum dispersion, and cartridge filling, ships to 15+ countries (with distributor partnerships in China since 2006), and claims a 95% customer retention rate across 500+ businesses served.
