We operate a fully self-contained in-house laboratory furnished with a comprehensive suite of testing instruments, delivering end-to-end performance testing and validation for PVC stabilizers and raw materials.

Our lab scope spans incoming raw material inspection, in-process mid-stream sampling, full-spec finished product verification, anti-aging evaluation, thermal stability profiling, physical property characterization, and compositional qualitative analysis. Every test is carried out independently onsite, eliminating the need for third-party lab outsourcing.
