Abstract
A process for producing cellular thermoplastic articles. The process comprises the steps of treating a solid parison made from a thermoplastic material with a saturating gas at an elevated pressure for a period of time to provide a gas-saturated parison; heating the gas-saturated parison to prepare a cellular parison; placing the cellular parison in a mold; and blowing a molding gas into the cellular parison to expand the cellular parison into the shape of the mold to provide a shaped cellular article.
