Abstract:
A gel has improved thermal stability and is the hydrosilylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a hydrosilylation catalyst and (D) a phthalocyanine. The (D) phthalocyanine is present in an amount of from about 0.05 to about 30 weight percent based on a total weight of (A) and (B). The gel has a hardness of less than about 1500 grams as measured after heat ageing at 225 °C for 1000 hours that is calculated as a weight required to insert a TA-23 probe into the gel to a depth of 3 mm.
Abstract:
A soft tacky composition comprising a polymer, in particular a silicone gel, is provided for use as a pottant (105) within a power converter (100), in particular a micro-inverter. The composition when cured, has a hardness measured by Shore A scale less than 30, thermal conductivity of no less than 0.2 W/m·K, and has a tacky surface. A power converter filled with the soft tacky gel and the process of manufacturing the power converter are also provided.
Abstract:
The removal of moisture from an object to be sterilized is provided through at least the steps of placing the load in the chamber, reducing the pressure within the chamber to increase the rate of evaporation of moisture from the load, monitoring over a predetermined period of time the increase in the quantity of vapor within the chamber resulting from evaporation of moisture from the load, admitting gas into the chamber and repeating the steps following placing the load into the chamber.
