Boosting the performance of Polylactic Acid with functionalized Calcium Carbonate
Omya Smartfill® 55 – OM is a new functionalized
Calcium Carbonate for use in biopolymers and in particular Polylactic Acid
Carbonate products lead to PLA degradation because of hydrolysis during
processing. Omya Smartfill® 55-OM demonstrates almost no hydrolysis when
processed at filler loads of up to 40%. At the same time, the addition of Omya
Smartfill® in films, sheets and injection molded items improves product
stiffness, impact resistance, elongation, heat transfer, and it contributes to
an overall reduction in formulation cost.
Omya Smartfill® is supplied as a powder and needs
to be pre-dispersed in a compound before being used on conventional single
screw extrusion lines.
Omya Smartfill® is derived from natural Calcium
Carbonate and a renewable material. The replenishment rate of Calcium Carbonate
from natural cycles far exceeds the consumption which makes it a renewable
material according to ISO 14021.
Omya recently received an Innovator Award from the Sustainable Packaging Coalition (SPC) as a member of PepsiCo’s Supply Chain Partnership to deliver a new bio-based film package to market. The outcome of a Partnership Innovator Award was one of a select few entries chosen for advancing the state of sustainable packaging. NatureWorks, Danimer Scientific, Berry Global, Johnson-Bryce and PepsiCo also received an award.
