Applications
Rigid and flexible sheets and films. Calendering is the application where thermal stability during processing earns its keep. Sheet stock sits on hot rolls for an extended thermal history, and a resin with poor stability shows it as yellowing and plate-out. The 1050 degree of polymerization gives the melt enough strength to draw into thin gauge without holes, and the max 0.3% volatiles keeps steam voids out of the web. Running the same grade for rigid and flexible sheet also lets a converter hold one resin silo instead of two.
Artificial leather. Coating and calendered leatherette lines depend on fast, even plasticizer absorption, because an under-absorbed blend separates and leaves soft spots in the coating layer. The porous suspension particle takes the plasticizer charge during dry blending, and apparent density of 0.53 ± 0.03 g/cm³ keeps the blend consistent batch to batch. Pair S-65 with DINP where the finished skin has to stay flexible and low-fogging in automotive interior trim, or with DOTP where phthalate-free specification applies.
Foamed products. Foam needs a melt that holds gas cells without collapsing or splitting. Medium molecular weight at K66 sits in the window where melt strength supports cell walls but viscosity stays low enough for the blowing agent to expand the matrix evenly. Low volatiles matter again here: moisture carried into a foaming melt produces coarse, irregular cells.
Flexible profile extrusion, tubing, and wire and cable insulation. Extruded flexible profiles and tube run at high plasticizer loadings, so the resin has to accept the full charge and still feed as a free-flowing powder. Thermal stability through the barrel controls whether a long production run finishes without a color shift or a degraded purge. For cable insulation, the max 1.0 ppm residual VCM supports compliance work on regulated construction and appliance wiring, and DOP or DINP remain the standard plasticizer choices for general-purpose insulation while TOTM covers higher continuous service temperatures.
Why Choose BASTONE
BASTONE sources Formolon S-65 through an established supply chain network rather than producing it. The resin ships with its original Formolon branding and the Formosa Plastics specification intact — no re-labeling, no substitution with a domestic equivalent. Buyers who have specified S-65 in a qualified formulation get the grade they qualified.
Quality control draws on the group's own chemical background. BASTONE operates four production sites and one R&D center in its own manufacturing lines, and the same technical staff vet sourced material, check COA data against the specification, and handle questions when a lot behaves differently on the line than the previous one.
Procurement is the practical advantage. BASTONE's plastics division supplies plasticizers — DOP, DOTP, DINP, DOA, TOTM — and additives alongside PVC resin, so a compounder can order resin and plasticizer on one contract, with one export entity, one documentation set, and one shipment to coordinate. Trade terms stay flexible, and logistics are arranged to fit the buyer's port and schedule.
