MARK 4781A is a liquid high efficiency non-Cd stabilizer for flexible PVC compounds.
MARK 4781A is a general purpose non-Cd stabilizer intended to be used in flexible PVC compounds requiring excellent process heat stability as well as excellent initial color hold. It will provide moderate temperature heat stability (MTHS) performance equal to or better than currently available Cd containing stabilizers while eliminating sulfide stain problems.
Utilizing the latest developments in technology, MARK 4781A can be used to replace exisiting Cd containing general purpose stabilizers in all types of flexible compounds whether processed via calendering, extrusion or injection molding. MARK 4781A imparts excellent clarity to clear compounds successfully resists calendar roll plate-out. |
