Title:
MODIFIED SILICONE RESIN FOAM
Document Type and Number:
WIPO Patent Application WO/2017/119396
Kind Code:
A1
Abstract:
Provided is a modified silicone resin foam which can be foam-molded without generating hydrogen as a byproduct, while maintaining excellent tactile properties or flexibility. The present invention is a modified silicone resin foam obtained by curing a foamable liquid resin composition including 100 parts by weight of a base material resin (A), 0.1-5 parts by weight of a silanol condensation catalyst, and 2-40 parts by weight of a chemical foaming agent, the modified silicone resin foam characterized in that the 100 parts by weight of the base material resin (A) comprises 65-95 parts by weight of a polymer (a) and 5-35 parts by weight of a reactive plasticizer, the polymer (a) has 1.0 to 2.0 reactive silicon groups in the molecular chain thereof, the main chain thereof comprising a polymer configured from oxyalkylene-based units, the reactive plasticizer (b) has 1.0 or fewer reactive silicon groups at one terminal end of the molecular chain thereof, the main chain thereof comprising a polymer configured from oxyalkylene-based units, and the elongation percentage of the foam is 300-1000% in a 25°C atmosphere.
