What RVD Materiais Dielétricos does

RVD Materiais Dielétricos is a Brazilian specialty manufacturer of electrical insulating materials, founded in 1992 and headquartered in Valinhos, São Paulo. The company produces a comprehensive portfolio including Kraft and Presspaper (RVDFLEX® Neutro and DDP), polyester and polyimide films (RVDFLEX® PES and PI), multilayer flexible laminates in thermal classes 130°C (B) through 180°C (H) under the TERCOTT® and THERNOMID® brands, pre-impregnated prepreg laminates, custom-converted kits, impregnating varnishes, and formulated epoxy (ROYAPOX®) and unsaturated polyester (DIAPOL®) resins. RVD also serves as the long-standing Brazilian and South American distributor of DuPont Nomex® aramid insulation products and integrates DuPont Kapton® polyimide film into its high-temperature laminate offerings.

The company's technology rests on materials formulation and precision conversion rather than software or digital platforms, with in-house capabilities spanning longitudinal cutting (5–1500mm width), rotary die-cutting, sheet cutting up to 2000mm, lamination up to 5 layers at 1340mm width, forming, and custom kit assembly. Products are designed into customer project specifications, with custom solutions developed for particular thermal, dielectric, and mechanical requirements.

RVD operates a sales-led B2B go-to-market, selling directly to industrial manufacturers of electric motors, generators, transformers (both dry and oil-immersed), voltage regulators, automotive electrical components, power tools, and home appliances, as well as to renewable energy and specialty industrial segments. Pricing is quote-based and not publicly disclosed, and the company holds ISO 9001:2015 quality management certification (UKAS-accredited). With 51–100 employees and no disclosed funding, M&A, or leadership transitions, RVD presents the profile of a mature, privately held regional industrial supplier.
