Plasticizer blends of ketal compounds
The present invention is directed to formulations including a polymer and a plasticizer composition. The plasticizer composition is a blend of an alkyl ketal ester plasticizer and a second plasticizer selected from a cycloaliphatic compound, an ortho phthalate compound, a terephthalate compound, a benzoate ester compound, and a bio-based compound. The plasticizer composition is at least 10% by weight of the total of the polymer and the plasticizer composition.
1. A plastisol formulation comprising, based on the total weight of the plastisol formulation:
i) between about 30-90% by weight of a polyvinyl chloride polymer;
ii) between about 5-30% by weight of the a first compound having the Structure (Ia):
and
iii) between about 5-30% by weight of the a second compound having the Structure
(II) that is selected from the group consisting of:
and combinations thereof,
wherein a plasticizer composition comprises a blend of the first compound and the second compound.
2. The plastisol formulation of claim 1 , wherein the plasticizer composition comprises at least 10% by weight of the first compound.
