Akcrostab™ T-5311

Very low odor liquid organotin mercaptide stabilizer for non-weatherable substrate and general purpose extrusion applications.


Akcrostab T-5311 is a state–of–the–art organotin, reverse ester mercaptide, heat stabilizer containing 9% tin. It is a cost-effective recommendation for the substrate layer of PVC co-extruded profiles, and other rigid PVC applications where weatherability is not critical. Akcrostab T-5311 exhibits the same color development profile and thermal stability, on an equal phr basis, as the leading substrate stabilizer. The suggested usage level is 0.7 to 1.5 phr depending on the heat stability required. Akcrostab T-5311 has been designed to contain a mercaptan chemical trap. This results in a uniquely low odor product, both in the neat stabilizer and during the extrusion process.
