Polystarch Additives

Polystarch Masterbatch Products
have been developed for use in blown film, injection molding and other applications of Polyethylene and Polypropylene resins. The Masterbatch contains a patented mix of compatabilizers and additives that alloy the starch to the plastic matrix. These formulations and their potential for use with a broad range of additives give...

Oxo-Biodegradable

PDQ
A non-starch based additive. This additive is loaded and works the same as PDQ-H. The
exception is that the end product will have a brownish tint.

PDQ-H
A non-starch based additive. This additive uses photo (UV) and oxidative methods to reduce the molecular weight of the plastic. After the molecular weight is reduced to a certain level, the biological process...

UV Degradable

UV-H
A non-starch based photo degradable additive. This additive is used in applications where only Photodegradation is required. The
recommended loading of this additive is 2-4% by weight, depending on the end product requirements. The end product manufactured with this additive will be clear. The end product manufactured with this additive must...

Aquanil/Desiccant

Water may sometimes be a problem in processing or reprocessing starch
based resins and also with other
water sensitive plastic resins such
as Polyethylene, Polypropylene,
Nylon, Polycarbonate, and PET.

Willow Ridge Plastics has developed AQUANIL, as desiccant for use, as needed, with these no-acid plastic resins and compounds...

Definitions

Degradation
The chemical, physical and/or biological process which leads to disintegration of the plastic.

Degradable Plastic
A plastic designed to undergo a significant change in its chemical structure under pecific environmental conditions resulting in a loss of some properties that may vary as measured by standard test methods appropriate to the plastic and the application in a period of time that determines ts classification.
