Abstract
The disclosure concerns a polymer foam comprising cellulose acetate propionate and a second polymer selected from a group several polymers, and at least one nucleating agent and the foam is manufactured by using at least one blowing agent. Furthermore, an article, a method and use related thereto are described.
Claims30
A polymer foam, characterized in that said polymer foam comprises
- cellulose acetate propionate (CAP),
- a second polymer selected from an aliphatic or an aliphatic-aromatic polyester, an aliphatic or an aliphatic-aromatic co-polyester, or a polylactide,
- at least one nucleating agent, and
- in that the polymer foam has been manufactured by using at least one blowing agent.
(canceled)
A method for manufacturing a polymer foam characterized in that the method comprises the following steps:
- providing cellulose acetate propionate (CAP) and a second polymer selected from an aliphatic or an aliphatic-aromatic polyester or an aliphatic or an aliphatic-aromatic co-polyester, or a polylactide,
- mixing said cellulose acetate propionate (CAP) and said second polymer with at least one blowing agent and at least one nucleating agent to obtain a polymer mixture,
- forming said polymer mixture into a polymer foam by using a foam producing method and obtaining a polymer foam.
