BASTONE's Polymer Contract Manufacture division produces masterbatch and polymer compounds to your exact formulation — pigment loading, additive package, carrier resin, and let-down ratio specified by your engineering team, not picked from a fixed catalog.

Backed by our production partners' extrusion and compounding lines across China, we run pilot-batch qualification through full-container production, with every shipment backed by a batch-traceable COA and your choice of FOB, CIF, or DAP delivery terms.
