Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from −55 to 300 °C (−70 to 570 °F) while still maintaining its useful properties.
RTV-2 (Two-component systems); two-component products that, when mixed, cure at room-temperature to a solid elastomer, a gel, or a flexible foam. RTV-2 remains flexible from −80 to 250 °C (−112 to 482 °F). Break-down occurs at temperatures above 350 °C (662 °F), leaving an inert silica deposit that is non-flammable and non-combustible.
No release agent is required, obviating post-production cleanup. Silicones also exhibit good chemical resistance and high-temperature resistance (205 °C, 400 °F and higher). For this reason, silicone molds are suitable for casting low-melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal).
Coming in second was a temperature of 70 or 71 (25.57%). But don't go too low. You might think you can set your thermostat very low and compensate for it with extra blankets or by dressing in layers.

While this is ultimately a personal choice, most experts recommend turning on the heat in your home when the outside temperature is less than 55 or 50 degrees, or when the indoor temperature dips ...
Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...
