Engineering Detail

The PVA that sets your PVC particle character.

GOHSENOL KH-17 is used worldwide as the primary suspending agent for PVC suspension polymerization. Its specific hydrolysis degree and viscosity define the stability of the VCM droplet in water, which in turn governs the PVC resin's particle size distribution, internal porosity, and plasticiser absorption. Used alone or blended with a secondary PVA such as L-series grades, KH-17 delivers the narrow PSD and high porosity that compound and film processors demand.

Industry-standard grade

KH-17 is widely specified across PVC producers in Asia, the Gulf, and Europe — proven compatibility with major reactor designs.

Primary PVA

Controls VCM droplet stability and sets the upper bound of particle size during the early polymerization phase.

Consistent batch-to-batch

Nippon Gohsei manufacturing discipline delivers tight hydrolysis and viscosity tolerances between lots.

Technical support

Blend recommendations and PVA pairing (with L-11, 552p) based on your target PVC grade and reactor design.

Compliance & Documentation

Documentation that clears customs and survives audit.

Chemical shipments require more paperwork than steel or equipment. We supply the full file with every formal quote — verified against current export and destination-country regulations before payment release.

Identification
CAS no., HS code, and UN no. (where applicable) supplied with formal quote, matched to your destination tariff schedule.
Safety & Quality
MSDS / SDS in EN/CN/AR, GHS classification, and COA per lot issued before shipment. REACH status confirmed where the destination requires it.
Export & Origin
CO Form A/E, packing list, B/L, and commercial invoice issued under our active Hong Kong import & export licence. Country-of-origin verifiable against factory registration.
Destination Permits
Many chemicals require an import permit in the destination country (Saudi SFDA, UAE MOCCAE, Iran MIMT, etc.). We confirm requirements before booking and flag long-lead approvals up front.

Documentation requirements vary by HS code, destination, and end-use. The list above is the standard package; project-specific certifications (e.g. food-grade, pharma-grade, halal, kosher) are quoted on request.
