The silicone elastomer null addition building a bridge Characteristic silicone

摘要

The target of this invention, being the addition building a bridge Characteristic silicone material (M), has the arukeniru basis 2 at least in such as (A)1 numerator, at least possesses the viscosity of 1000000mPa s, at the same time 0.3 mols % possesses the arukeniru basis, the polydyorganosiloxane 100 mass section of arukeniru basic content and, (B) the SiH functionality building a bridge medicine and, (C) the hydrosilyl conversion catalytic converter and, (D) specific surface² the additional strength Characteristic² bulking agent 10 - 80 mass sections which possess 50m/g - 350m/g and, (E) to possess viscosity 20 - 5000mPa s, to possess the basis which₁ is chosen from₆ the phenyl group and C - C alkyl group, all basesAt least 5 mols % it contains with the silicone oil which is the phenyl group, it is silicone elastomer it can production manner of the addition building a bridge Characteristic silicone material (M) and the said addition building a bridge Characteristic silicone material (M), by building a bridge of the said addition building a bridge Characteristic silicone material (M).
