Block copolymer foam additives |
| abstract |
The present invention provides an additive for thermoplastic polymer foams which provide for enlarged cell size or with decreased density with minimal impact on the thermal mechanical properties of the thermoplastic foam. The additive is an essentially block copolymer blowing agent compatibilizer. Including the additive in a thermoplastic foaming composition comprised of a thermoplastic polymer resin and a physical blowing agent provides for the production of foam having enlarged cell size or with decreased density and minimal impact on the thermal mechanical properties of the thermoplastic foam. The block copolymer compatibilizer has at least a first block having at least one functionality compatible with the thermoplastic resin and at least one second block having a functionality compatible with the blowing agent. |
