摘要

Material composition (A) for the production of molded parts, with formation of a cross linked polymer material, comprises at least one silicon containing polymer (I), which is formed by cross-linking silicon containing structures under UV-radiation in a continuous manufacturing method. An independent claim is also included for a method for cross-linking (I) comprising plasticizing (I) and forming molded parts in a continuous manufacturing method (which exhibits: wall thickness of more than 0.5 mm; a manufacturing speed of 5-100 m/min under irradiation of UV light; wavelength of 120-450 nm; radiation intensity in the UV range of 10-100 W/cm and emission from at least monochromatic and/or polychromatic UV-radiation source, comprises a excimer-laser (xenon fluoride, xenon chloride, krypton fluoride, krypton chloride-laser), a excimer lamp (xenon chloride, krypton chloride or krypton bromide lamp), a mercury vapor lamp with microwave- or light arc stimulation, a mercury vapor lamp with iron or gallium-indium or gallium-lead doping), on which UV light contacts before or after hardening the plasticized (I) and which is cross-linked under formation of silicon containing structures, where after the UV cross-linking with cross-linking degree of 50-98% (preferably 70-80%) and/or the course deformation residue (measured according to DIN ISO 2285 at 70[deg]C) amounts to 10-50% (preferably 10-20%).
