Halogenated alkene heat transfer composition with improved oil return

Blowing agent based on HFC-134a and cyclopentane for the expansion of polymers

Polymer foams containing nanoclay are provided, the foams having improved properties such as thermal insulation values.

Polymer foam containing nanoclay

Foam blowing agent blends of D11 and a pentane are provided, as are polyol premixes containing such blends. The resulting foams exhibit dramatic improvement in fire resistance.

Blowing agent blends

Inhibition of the formation of unsaturated carbon compounds during the heating of 141b involving the addition of various inhibitors such as butylene oxide and/or the use of a vessel made of a nickel alloy.

Inhibition of 141b decomposition

PVC foam blown with a physical blowing agent comprising a gaseous HFC is provided.

PVC foam

Inhibition of the formation of unsaturated carbon compounds during the heating of 141b involving the addition of various inhibitors such as dialkylhydroxylamine and/or the use of a vessel made of a nickel alloy.

Foam blowing agents blends of 10-90% of n- and/or i-pentane with 90-10% of 142b or 124 are provided, as are polyol premixes and polyurethane foam compositions containing such blends.

Inhibition of 141B decomposition

Storage-stable 141b prepared by contacting 141b with alumina at temperatures of about 0-100 degrees Centigrade, compositions containing the thus treated 141b, and uses thereof for the production of polyurethane and polyisocyanurate foams.
