Pipe & Fittings

Aimsea’s lead‑free calcium‑zinc PVC stabilizers give pipe and fitting manufacturers a mature, cost‑effective formulation that delivers low precipitation, smooth extrusion and excellent fusion control. With superior processability, they help you hit ISO 4422 and ASTM D1785 performance targets while meeting global RoHS, REACH, and potable‑water regulations—driving higher throughput and fewer rejects.

Product advantages

志海

High cost-effectiveness(mature)

Field‑proven Ca‑Zn PVC stabilizer technology offers a low‑cost alternative to tin systems while meeting ISO 4422/ASTM D1785 pipe standards.

志海

Low precipitation

Precision particle control minimizes chalk‑out, keeping compound viscosity stable and ensuring uniform wall thickness.


志海

Good processing performance

Fast fusion and a broad thermal window support high‑speed extrusion with fewer die clean‑outs.
