Estimating the term…
A bio-resin composition contains cellulose acetate and a biodegradable secondary polymer in a ratio of at least 10:1 by weight of the total weight of the composition wherein the secondary polymer is an aliphatic polyester such as polybutylene succinate or an aliphatic co-polyester such as polybutylene succinate adipate or an aliphatic/aromatic polyester such as polybutylene adipate terephthalate. The secondary polymer may be present in an amount up to 10% by weight, more preferably up to 6% by weight and more preferably still in the range 2% to 3% by weight of the total weight of the composition where the combined amount of secondary polymer and cellulose acetate may be up to 85% of the total weight of the composition.
A bio-resin composition containing a blend of polymers including cellulose acetate and a biodegradable secondary polymer wherein the cellulose acetate and biodegradable secondary polymer are present in a combined amount of up to 85% by weight of the total weight of the composition, the biodegradable secondary polymer is selected from the group comprising aliphatic, aromatic and mixed aliphatic/aromatic polyesters and the ratio of cellulose acetate to biodegradable secondary polymer is at least 10:1.
A bio-resin composition containing a blend of polymers including cellulose acetate and a biodegradable secondary polymer wherein the biodegradable secondary polymer is selected from the group comprising aliphatic and aliphatic/aromatic polyesters and the ratio of cellulose acetate to biodegradable secondary polymer is at least 10:1 by weight.
A bio-resin composition containing cellulose acetate and a bio-degradable polyester selected from the group comprising polybutlyene succinate, polybutylene succinate adipate, and polybutylene adipate terephthalate and mixtures and derivatives thereof wherein the biodegradable polyester is present in an amount up to 10% by weight of the total weight of the composition.
