METHOD TO ENHANCE CELL NUCLEATION DENSITY IN SOLID-STATE FOAMS |
| 摘要 |
A method for creating a foam from a solid thermoplastic material is disclosed. The method includes heating a solid, noncellular thermoplastic material to a temperature greater than the material's glass transition temperature, and below the melting temperature, and then allowing the material to cool; after the material has cooled, saturating the cooled thermoplastic material with a non-reacting gas to provide a gas-saturated material; and heating the gas-saturated material below the melting temperature of the material so that the material remains a solid, and causes nucleation of bubbles, and creation of cells in the material. |

1. A method for creating a cellular thermoplastic material, comprising:
(a) heating a solid, noncellular thermoplastic material to a temperature greater than the material's glass transition temperature, and below the melting temperature, and then allowing the material to cool and solidify; (b) after the material has cooled, saturating the cooled solid thermoplastic material with a non-reacting gas to provide a gas-saturated material; and (c) heating the gas-saturated solid material below the melting temperature of the material so that the material remains a solid and causes nucleation of bubbles and creation of cells in the material. |
