Akcrostab™ T-5314

A butyl tin stabilizer with high performance processability and superior stabilization, Akcrostab T-5314 is a more cost effective option to competitive weatherable tin stabilizers.


Akcrostab T-5314 is a new generation (19% Butyl Tin) PVC stabilizer. It is more cost – effective than older high efficiency stabilizers, while retaining their performance characteristics of excellent color hold, processing and weatherability. Akcrostab T-5314 has shown good weathering characteristics in weatherable formulations, making it suitable for use in PVC siding, topcoat, and window profiles applications. It exhibits good early- to mid- color hold and retains the same extrusion behavior as older high efficiency stabilizers including moderate external lubricity. It is also suitable for molding applications, highly filled or interior profile applications, clear extrusion, and calendering applications where excellent color hold and clarity are needed. Its suggested use level is 0.7 to 1.0 phr. This makes it more easily metered and dispersed in the PVC compound than more concentrated stabilizers.
