What Diamorph does

Diamorph AB (publ) is a Swedish-registered, publicly structured industrial group that supplies advanced material solutions for safety-critical and high cost-of-failure applications. The company operates through three business units — Composite and Polymer Materials (CPM), High Temperature Solutions, and Passive Fire Protection — each anchored by a portfolio of heritage sub-brands including Tenmat Wear, Permali, Tufnol, Railko, Hob Certec, PFC Corofil, and the Tuftane TPU film line. Its technical capabilities span ultra-tough composites, laminated composites, thermoplastic polyurethane films (30+ grades), ceramic solutions rated to 1000°C, and passive fire stopping products, supported by AS9100 Rev D, ISO 9001:2018, and ISO 14001:2015 certifications at the 10,500 sqm Gloucester manufacturing site.

The company's revenue model is built on direct B2B sales of OEM materials to industrial customers, supplemented by custom material development for demanding specifications. It serves a diversified base across aerospace (Formula 1 teams, Rolls-Royce), defence, rail, marine, construction, oil and gas, mining, medical, and process industries (steel, aluminium, glass, ceramics), with more than 61% of revenue generated outside the UK & Ireland. Manufacturing is concentrated in the UK (Gloucester, Manchester) and Czech Republic (Horní Bříza), with sales offices in the USA, Italy, Germany, and Czech Republic, plus channel partnerships through NBS Source and the Association of Brickwork Contractors to reach UK construction specifiers. Go-to-market blends direct enterprise sales, trade show presence (JEC World, FILTECH), and specification platforms for building products. Pricing is quote-based and bespoke rather than publicly disclosed, reflecting the engineered, low-volume nature of the products.

Products and services

• Tuftane TPU Films Thermoplastic polyurethane (TPU) elastomeric films manufactured by Permali in over 30 grades, supplied in rolls up to 1.6m wide. Used in medical (e.g. University of Oxford tendon tissue research), aerospace, automotive, construction and industrial applications requiring tough, highly elastic flexible films.
• TUFNOL Laminated Composites High-performance fabric-base laminated composites under the TUFNOL brand (including Whale and Carp variants), providing chemical resistance, light weight and ease of machining. Used by industrial customers such as Rolls-Royce Derby works for etch baskets in chemical component processing, delivering four times the life of metal predecessors.
• Tenmat Firefly Hot Gas Filter Elements High-temperature hot gas filter elements branded Firefly, safe to operate up to 1000°C, designed to emit cleaner emissions and resist most chemicals. Targeted at filtration industry and high-temperature process operators.
• Ferosafe Lock Box Anti-theft shipping and storage container lock box using Ferosafe Anti-Cutting Technology, resisting more than 10 grinding discs and a full battery worth of angle grinder attacks. Constructed from powder-coated galvanised steel.
• Tenmat Wear Tenmat Wear product line of ultra-tough composites and wear parts engineered for endurance and security in demanding industrial applications.
• Permali Permali product line of advanced composites and TPU films for defence, aerospace and motorsport excellence, including the Tuftane TPU film range.
• Tufnol Tufnol product line of high-performance laminated composites for strength, precision and versatility across industrial applications.
• Hob Certec Hob Certec product line of innovative ceramic solutions for high-temperature and filtration applications, headquartered at the Horni Briza (Czech Republic) facility.
• PFC Corofil PFC Corofil product line of passive fire protection products, including cavity barriers, fire stops and brickwork façade fire protection for building construction.
• Railko Railko product line of composite bearing solutions for rail applications, part of the Gloucester-based Composite and Polymer Materials operations.

Quantifiable outcome
