What Cb Frost does

CB Frost & Co Limited is a UK-based specialist rubber, sponge, foam, and plastics converter founded in 1921 and headquartered in Birmingham. The company manufactures precision-engineered components, including gaskets, seals, washers, strips, sheets, extrusions, moulded parts, machined plastics, and adhesive-laminated products, through die cutting, rubber moulding, extrusion, and custom fabrication processes. Core competencies include conversion of high-performance materials such as Rogers BISCO silicones and PORON urethanes (via a 30+ year preferred converter relationship), Armacell Armaflex closed-cell insulation foams, and Zotefoams AZOTE/ZOTEK foams, with in-house die cutting forme manufacture providing vertical integration.

The company's primary vertical is UK rail and mass transit, where it supplies EN45545-2 (HL1-HL3), BS6853, UL94 V-0/HF-1, LUL S1085, and NFF-16-101 compliant materials for rolling stock OEMs, train operators, and infrastructure projects including Crossrail, Rail Floating Floor, and London Underground (Transport for London Victoria and Sub-Surface Lines). Secondary verticals include UK Ministry of Defence land and naval systems (30+ year approved supplier, including a £60k Boxer armoured vehicle contract), automotive NVH and weather sealing, EV/HEV battery thermal management (entered 2022), HVAC, construction, solar/energy, lighting, agriculture, and enclosures.

Revenue is generated through three streams: one-time e-commerce sales of standard sheet and strip materials (priced £3.00-£892.50 per unit), bespoke custom manufacturing and conversion services priced via consultation, and adhesive lamination services. Distribution combines a direct B2B sales model with technical material consultation, an own-storefront e-commerce shop for SMB and individual buyers, and engagement at industry exhibitions (Rolling Stock Networking, Rail Industry Technology Roadshow). Delivery within mainland UK is typically next-day for stock items and 7-10 days for non-stock items, with the company operating from a single Birmingham facility employing 11-50 staff.
