100 parts by mass of (A) an organopolysiloxane containing an alkenyl group,
0.2-20 parts by mass of (B) an organohydrogenpolysiloxane containing a hydrogen atom bonded to a silicon atom,
(C) a catalyst based on a platinum-group metal, the amount of which is 0.5-500 ppm in terms of platinum-group metal amount (in mass) with respect to the total mass of the components (A) and (B),
1-10 parts by mass of (D) a specific phenyl-group-containing organopolysiloxane,
1-25 parts by mass of (E) a specific nonfunctional dimethylpolysiloxane, and
(F) a specific benzotriazole derivative, the amount of which is 2-100 mol per mol of the platinum atoms contained in the component (C).

The oil-bleeding silicone rubber composition gives cured objects having improved heat resistance, without containing any of conventional additives for improving heat resistance.

Abstract: The invention relates to a sterilizable and reusable ultraviolet-resistant elastomer composites including an elastomeric matrix comprising at least one elastomer; and an UV-resistant additive incorporated into the elastomeric matrix. The ultraviolet-resistant elastomer composite remains mechanically robust over at least 150 sterilization cycles, enabling safe reuse following ultraviolet germicidal irradiation (UVGI). Beyond N95 masks, these UVGI-compatible ultraviolet-resistant elastomer composites have potential utility in other PPE applications to address the broader issue of single-use waste.
