  • Publication number: 20240076436
    Abstract: The present disclosure relates to a polyurethane foam composition, comprising (A) a polyol component, comprising one or more polyols selected from the group consisting of a polyester polyol, a polyether polyol, and the combination thereof, wherein the one or more polyols have an average hydroxyl group functionality of from 3 to 7 and an average hydroxyl group number of from 300 to 1000 mg KOH/g; and (B) an isocyanate component, comprising one or more isocyanate compounds; wherein in either or both of the (A) polyol component and the (B) isocyanate component, the polyurethane foam composition further comprises one or more flame retardants in an amount of no more than 15 percent by weight based on the total weight of the polyurethane foam composition, and, one or more blowing agents; and wherein the NCO/OH ratio of the isocyanate component to the polyol component is within the range of from 0.5:1 to 5:1.

  • Patent number: 9825390
    Abstract: An improved connection apparatus that meets these and other needs includes, in one embodiment, an approximately J-shaped flexible conductor having at its end an opening that receives therethrough a portion of the shank for mechanical and electrical connection therebetween. The conductor further includes a hole formed therein at approximately its midpoint that receives therein, in a movable and non-contacting fashion, another portion of the elongated shank. In another pair of embodiments, another connection apparatus includes a flexible conductor that is co-formed with a rigid conductor to form a single piece unitary element. The free end of the flexible conductor is connected with the movable shank, and the rigid conductor is connectable with the primary conductor of the circuit. By providing the flexible conductor and the rigid conductor as a co-formed unit, a detachable fastener need not be employed to provide a connection therebetween, which reduces heat generation.
