KEBABLEND / RS 49.1800 PA 12

KEBABLEND / RS are special compounds based on different polymers for applications through which radiation is to be shielded. KEBABLEND / RS 49.1800 PA 12 was developed for applications that are to shield soft and hard X-ray radiation. The physical properties of the filler systems used make them particularly suitable for absorbing or attenuating radiation up to 600 keV. Processing by injection molding allows a particular degree of design freedom. Despite the high filler content, KEBABLEND / RS 49.1800 PA 12 has excellent mechanical properties.



KEBABLEND is a wide range of functional compounds, often tailor-made to customer requirements. Under the trade name KEBABLEND, we market magnetizable, thermally or electrically conductive compounds, high-density injection molding materials, compounds for radiation protection applications, detectable plastics and much more.
