PSU Supply in Korea | BASF Ultrason® S (Polysulfone)

BASF Ultrason® S 2010 is the equivalent standard-viscosity transparent PSU injection grade, matching on tensile strength and HDT. Octud supplies it from Korean stock with evaluation samples.

PSU is widely used for potable-water and non-food applications. However PSU is BPA-based, so for EU food contact it is subject to recertification under Regulation 2024/3190. For high-temperature food contact, consider PPSU (Ultrason® P 3010), made without BPA or BPS.

Yes — where a part must stay transparent but needs higher heat, hydrolysis and chemical resistance than PC. Where notched impact matters, PPSU is preferable.

Yes. Octud is the official distributor and holds BASF Ultrason® S 2010 and the high-viscosity S 3010 / S 3010 MR / S 6010 grades in Korean stock — in-stock material ships and arrives anywhere in Korea within 1–2 days; non-stock grades are quoted with lead time.

Yes. Octud does not run its own molding machines, but we deliver part projects together with partner molders experienced in PSU. Send the drawing, quantity and requirements (potable-water contact, electrical insulation, etc.) — we review grade selection and processing conditions first, obtain the partner molder's quotation and quote you per molded part. If you already have a molder, we support with material, colorant and processing data only.

Yes. Octud is an official Avient Colorant Chromatics™ distributor and supplies sulfone-specific masterbatch (colour concentrate) with minimal colour shift at high processing temperatures, matched to RAL or Pantone references. Both transparent tints and opaque colours are possible on PSU; let-down ratios are confirmed after colour-sample approval.
