Geba Polymer Compounds

Geba Kunststoffcompounds GmbH is a German family-owned compounder producing high-performance thermoplastic compounds for the automotive, electrical, appliance, and industrial sectors. Supplied to the UK market by Abbey Polymers, the Geba portfolio spans polymer alloys, flame-retardant compounds, and single-polymer technical grades, all available in prime and recycled formulations.

Geba’s compounds are organised into product families by polymer type, from the Gebablend alloy range through to flame-retardant polycarbonate, PBT, PMMA, and ASA grades. Every family is backed by in-house colour matching, long-standing automotive OEM approvals, and the consistency required for high-volume production. Abbey Polymers stocks and supplies grades from across the Geba range, providing UK manufacturers with reliable access alongside expert technical support.

The Geba Product Range

Each Geba product family is built around a specific polymer or polymer blend, giving a targeted performance profile for different application requirements. Reinforced, flame-retardant, UV-stabilised, and recycled options are available across the range, along with full colour matching to RAL, Pantone, HKS, and custom specifications including metallic and special-effect finishes.

Gebablend (Polymer Alloys)

Polymer base: PC/ABS, PC/ASA, PC/PBT, PBT/ASA

Gebablend is Geba’s alloy range and the product family for which the company is best known. Each blend combines two engineering polymers to balance impact strength, heat resistance, surface quality, and chemical or weather resistance. Gebablend PC/ABS holds long-standing OEM approvals for automotive interior applications and is available in all current interior colour specifications for leading European marques.

PC/ABS: High impact and notched impact strength with excellent thermal resistance and surface finish. Available across a range of PC-to-ABS ratios and with glass fibre reinforcement.
PC/ASA: Hard and scratch resistant with a high-gloss finish straight from the mould, removing the need for a painting process. Excellent UV stability and weatherability.
PC/PBT: High toughness combined with strong resistance to fuels, oils, and cleaning agents, plus good scratch resistance and stiffness.
PBT/ASA: Chemical resistance and mechanical performance from the PBT, with weatherability and long-term colour stability from the ASA.

Typical applications: Display surrounds, centre consoles, storage compartments, air vents, overhead control units, rear-light housings, exterior trim, connectors, sensor housings, and outdoor enclosures.

Gebalon Ultimate (Flame-Retardant Polycarbonate)

Polymer base: PC

Gebalon Ultimate is Geba’s halogen-free flame-retardant polycarbonate range, UL listed to V0 and available unfilled or with 10% and 20% glass fibre reinforcement. It combines polycarbonate’s inherent impact strength and high heat deflection temperature with certified fire safety performance, and is available in the full colour range rather than being restricted to natural or black.

This family is used predominantly in electrical and electronic applications where housing components must meet flammability requirements without compromising on mechanical performance or appearance.

Typical applications: Electrical enclosures and housings, switchgear components, distribution equipment, IT and telecoms housings, and appliance parts requiring UL-certified flame retardancy.

Gecomblend (Flame-Retardant PC/ABS)

Polymer base: PC/ABS

Gecomblend is Geba’s flame-retardant PC/ABS range, offering halogen-free V0 rated grades. It brings together the impact strength, heat resistance, and surface quality of a PC/ABS alloy with certified flame retardancy, making it a strong option where a standard Gebablend grade would meet the mechanical requirement but not the fire safety specification.

Typical applications: Electrical and electronic housings, appliance components, IT equipment enclosures, and industrial parts where flame retardancy and impact performance are both specified.

Gebadur (PBT)

Polymer base: PBT

Gebadur is Geba’s polybutylene terephthalate range, available unfilled and with glass fibre reinforcement. PBT’s low coefficient of thermal expansion and very low moisture absorption give it excellent dimensional stability, making it well suited to precision-moulded technical components that must hold tight tolerances in service. It also offers strong chemical resistance and good electrical properties.

Typical applications: Connectors, terminal blocks, sensor housings, precision technical mouldings, and automotive components exposed to oils, fuels, and cleaning agents.

Gebacryl (PMMA)

Polymer base: PMMA

Gebacryl is Geba’s polymethyl methacrylate range, offering high transparency, hardness, and excellent surface quality. PMMA is resistant to weathering and ageing and stands up well to acids and alkalis at medium concentrations, making it a common choice for visible and optical components. Recycled Gebacryl grades are used in visible automotive exterior applications, demonstrating that recycled content and appearance-critical parts are compatible.

Typical applications: Lenses and light guides, badges and emblems, decorative trim, display covers, signage, and optical or visible components where clarity and surface finish are critical.

Gebaran (ASA)

Polymer base: ASA

Gebaran is Geba’s acrylonitrile styrene acrylate range. The acrylic ester rubber content gives ASA markedly better weathering resistance and heat deflection performance than ABS, with UV-stabilised grades available for prolonged outdoor exposure. Colour and gloss are retained over long service life without the need for painting or coating.

Typical applications: Exterior automotive trim, outdoor housings and enclosures, garden and leisure products, construction components, and any visible part subject to sustained UV exposure.

The families above represent the Geba grades most commonly specified by UK manufacturers. Geba’s wider portfolio also includes ABS, PA6, PA66, and POM technical compounds, TPU ranges, microgranulates, and high-performance polymers such as PEEK, PEI, PES, PVDF, PPS, and LCP. Abbey Polymers can source and supply grades from across the full Geba range to suit specific project requirements.

Features and Benefits of Geba Compounds

Proven OEM Approvals: Gebablend PC/ABS holds long-standing approvals from several major European vehicle manufacturers, providing confidence that the material meets the stringent quality, performance, and consistency standards required for automotive production.
Certified Flame Retardancy: Gebalon Ultimate and Gecomblend offer halogen-free, UL-listed V0 grades, giving third-party verified fire safety performance for electrical and electronic applications.
Extensive Colour-Matching Capability: Geba’s in-house colour laboratory can match RAL, Pantone, HKS, and custom colour specifications, including metallic and special-effect finishes. For automotive applications, grades are available in all current interior colour standards for leading OEMs.
Prime and Recycled Options: Product families across the range are available in both prime (virgin) and recycled formulations, allowing manufacturers to meet sustainability targets without changing material specifications or supplier.
Breadth of Polymer Choice: With alloys, flame-retardant grades, and single-polymer technical compounds available from one compounder, material changes across a product family can be managed without adding new suppliers to the approved list.
Excellent Surface Finish: Geba compounds are formulated to deliver high-quality surface aesthetics directly from the mould, reducing or eliminating the need for secondary finishing operations.
Good Processability: Consistent flow characteristics and predictable shrinkage behaviour support efficient processing on standard injection moulding equipment in high-volume production.
Goal Zero Sustainability Commitment: Geba operates under its Goal Zero programme, targeting climate-neutral production by 2030. Recycled grades contribute to circular economy objectives while maintaining full technical performance.

Typical Applications for Geba Compounds

Geba compounds are used across industries where a combination of mechanical performance, surface quality, and chemical, thermal, or environmental resistance is required. Typical applications include:
