What Cuming Microwave does
Cuming Microwave, founded in 1986 and headquartered in Avon, Massachusetts, is the manufacturer and supplier of low-loss dielectrics, conductive materials, and standard and custom electromagnetic (EM) absorbers, operating as a product brand under PPG Aerospace, which is a division of PPG Industries, Inc. (NYSE: PPG), the publicly traded Fortune 500 coatings and specialty materials conglomerate. The portfolio spans two proprietary brands: C-RAM (radar absorbing materials, including flexible foam absorbers RGDS, FLX, LF, and MT; broadband pyramidal absorbers SFC; high-power honeycomb pyramidal absorbers SFC-HC; broadband honeycomb absorbers HC; iron/epoxy casting resin KR; and sprayable absorbers) and C-STOCK (low-loss dielectric materials, including C-STOCK AK plastic stock with adjusted dielectric constant and C-STOCK RH low dielectric constant structural foam). Cuming Microwave serves a 48-SKU catalog across nine product categories, addressing RF absorption, microwave absorption, EMI mitigation, radar cross-section reduction, anechoic chamber construction, and electromagnetic testing use cases primarily for aerospace and defense customers, with secondary demand from EMC testing laboratories.
Cuming Microwave's business model is built on quote-based, project-specific sales of engineered specialty materials rather than standardized commodity pricing; pricing is not publicly disclosed and bespoke configurations (e.g., radar absorbing structures, custom anechoic chamber builds) drive project economics. Go-to-market runs through PPG Aerospace's global direct sales force, a dedicated aerospace product catalog on ppg.com, and the dedicated e-commerce storefront ppgaerospacestore.com, where buyers can purchase standard items or submit "Additional Product" inquiries for non-catalog specifications. Distribution is global, leveraging PPG's worldwide aerospace footprint to reach OEM, Tier 1, government/defense, and EMC laboratory customers. Customer segmentation is vertical-focused, with aerospace and defense as the primary segment (stealth, EMI shielding, structural RF absorption) and electromagnetic testing laboratories as a secondary segment. The company is classified in PPG's product taxonomy as an acquired brand within the Aerospace business unit, with no separate corporate entity, subsidiaries, or independent funding structure.
Commercially, Cuming Microwave's revenue and growth are not disclosed at the brand level, instead rolling up into PPG Industries' consolidated reporting. There is no public management team data beyond founder William R. Cuming (named as founder) and a purchasing manager (Michael Goossens), consistent with a lean 51-100 employee operations absorbed into a larger corporate parent. There are no disclosed partnerships, awards, patents, regulatory actions, or mergers and acquisitions specific to the brand in the supplied data; competitive positioning rests on domain specialization (a deep catalog of qualified RF/microwave absorber SKUs), brand reputation across decades of aerospace and EMC test deployment, and the distribution leverage provided by PPG Aerospace.

Cuming Microwave product offering
Product offeringCore offering
Cuming Microwave manufactures and supplies low-loss dielectric materials, conductive materials, and standard and custom electromagnetic (EM) absorbers. The portfolio consists of two main product lines: C-RAM radar absorbing materials (flexible, pyramidal, honeycomb, elastomeric, castable, and sprayable absorbers) and C-STOCK dielectric and structural materials (plastic stock with adjusted dielectric constants and low-loss structural foam). These products are designed for RF/microwave absorption, radar cross-section reduction, EMI mitigation, and anechoic chamber construction.
Product overview
Cuming Microwave is a product portfolio under PPG Aerospace consisting of specialized RF and microwave absorption materials. The portfolio includes two main product lines: C-RAM (radar absorbing materials) and C-STOCK (dielectric and structural materials). C-RAM products encompass flexible foam absorbers (RGDS, FLX, LF, MT), pyramidal RF absorbers (SFC), honeycomb absorbers (SFC-HC, HC), casting resins (KR), and sprayable absorbers. C-STOCK products include plastic stock with adjusted dielectric constants (AK) and low-loss structural foams (RH). These materials serve anechoic chamber construction, radar cross-section reduction, and electromagnetic interference mitigation across aerospace, defense, and telecommunications applications.
