Abstract
A method of making a solid foam material including the steps of heating in a chamber a starting material that is normally solid at room temperature to a temperature that is above its melting point, injecting a blowing liquid into the melted material to produce a mixture; and rapidly decompressing the mixture to produce the solid foam material.
Claims16
A method of making a solid foam material comprising:
- in a chamber heating a starting material that is normally solid at room temperature to a temperature that is above its melting point;
- injecting a blowing liquid into the melted material to produce a mixture;
- and
- rapidly decompressing the mixture to vaporize the blowing liquid so that its latent heat of vaporization cools the starting material sufficiently to produce the solid foam material.
