SILICONE MIXTURES WITH IMPROVED RESISTANCE TO FURTHER TEARING

A silicone composition including: at least two reactive polydiorganosiloxane polymers P1 and P2 that together account for 20% to 60% by weight, based on the overall silicone composition; at least one crosslinker for polydiorganosiloxanes, with a proportion of 0.5% to 5% by weight, based on the overa...

Zusammenfassung:	A silicone composition including: at least two reactive polydiorganosiloxane polymers P1 and P2 that together account for 20% to 60% by weight, based on the overall silicone composition; at least one crosslinker for polydiorganosiloxanes, with a proportion of 0.5% to 5% by weight, based on the overall silicone composition; at least one catalyst, with a proportion of 0.001% to 0.1% by weight, based on the overall silicone composition; at least one optionally hydrophobized filler, selected from precipitated or fumed silica and ground or precipitated chalk, with a proportion of 10% to 70% by weight, based on the overall silicone composition, wherein the reactive polyorganosiloxane polymer P1 has a higher reactivity in the condensation crosslinking with the crosslinker than the reactive polyorganosiloxane polymer P2 and the molar ratio P1:P2 in the composition is between 0.1 and 15.
