The product is Fluorescent Brightener OB-1 designed for plastic processing. It appears as a yellow powder that is insoluble in water and odorless, offering stable performance. Optical measurements show a maximum absorption at 374 nm and a strong fluorescence emission at 434 nm. The material is milled to 300 mesh fineness and classified as a whitening agent.
In the plastics industry OB‑1 is commonly added to polyester resins to improve visual brightness. Typical formulation levels range from 0.1 % to 0.5 % by weight, providing a noticeable shift toward blue‑white light without affecting mechanical properties. The agent remains effective across a storage temperature of 15 - 25 °C and tolerates the processing temperatures of most thermoplastic extrusion processes. Its insolubility in water prevents migration during downstream washing steps.
Manufacturers of transparent or lightly coloured plastic films, automotive interior components and consumer goods employ OB‑1 to meet aesthetic specifications. Buyers such as polymer compounders, OEMs and contract manufacturers source the brightener in bulk, usually in 25 kg or larger bags. Specific minimum order quantities, pricing and incoterms are not disclosed in the listing; interested parties should request a quotation and confirm payment and shipping terms directly with Nuhai(Yantai)Chemical Co., Ltd.

Before placing an order, buyers should request a current material safety data sheet and confirm the batch number to ensure traceability. It is advisable to ask for a certificate of analysis that details purity and the measured absorption/emission peaks. Verifying that the supplied product matches the 300 mesh fineness can prevent processing issues.
Logistics arrangements, including lead time, FOB or CIF terms and port of loading, are not detailed in the public listing and must be negotiated with Nuhai. Importers typically confirm the preferred incoterm and request a pro‑forma invoice that outlines payment milestones. Common payment methods include T/T against documents or escrow services, but the exact terms should be agreed with the supplier.
On arrival, a third‑party inspection can verify particle size distribution and fluorescence performance using spectrophotometric methods. Buyers may also conduct a small‑scale trial to assess colour shift in the intended plastic matrix. Retaining the test reports and batch records will support compliance with downstream quality standards.
