Unistars Plastics Additives recently showcased its flagship methyl tin stabilizers — XY-728 and XT-188 — to an international audience of PVC processors, packaging manufacturers, and packaging converters. The demonstration highlighted how Unistars’ custom-formulation approach helps customers reduce raw material costs while improving product quality.
Key takeaways from the event:
- XY-728 remains the top choice for all-around clear PVC processing, with tin content ≥19% and color ≤50 Pt-Co
- XT-188 is increasingly specified by film converters for heat-shrink packaging films, with recommended dosage of 1.6-2.0 phr
- Unistars’ customized stabilization service, launched in 2018, has helped customers achieve up to 12% raw material cost reduction
