Fire-resistant compounds
At Bekina® Compounds, fire-resistant compounds are developed with an emphasis on safety and environmental friendliness. All our compounds are based on halogen-free flame retardants such as ATHs (aluminium trihydroxides), which help reduce smoke development and minimise harmful by-products during combustion. Moreover, they do not contain heavy metals. Depending on the requirements, loading levels of up to 80% may be needed to achieve the desired level of flame retardancy. With internal mixers, such high filling levels are achievable without compromising processability or the quality of the final product.
These compounds are used primarily in infrastructure (buildings, data centres, rail, telecom) and in oil and gas (on drilling platforms to protect pipelines from so-called jet fires), but also in shipping, the (process) industry, energy and automotive. It can also be adapted to fire safety standards such as UL94, EN 45545-2 and others, depending on customer requirements and application.
Our fire-resistant compounds are made from polymers such as: EPDM, Silicone (VMQ), EVA, FKM, NBR,...
