Import Bmp (Butynediol Propoxylate) (C10h18o4) — Buy in wholesale FOB from Supplier in China

Butynediol Propoxylate (BMP) with molecular formula C10H18O4 is a propoxylated diol intermediate used primarily in polyurethane formulations for flexible foam and elastomer production. Supplied by Wuhan Silworld Chemical Co., Ltd. from China, this material presents as a clear brown liquid with low viscosity and broad compatibility with solvents and polymers. The propoxylated structure derived from butynediol introduces ether linkages that modify chain flexibility and reactivity in polyol systems, making it distinct from ethoxylated or non-alkoxylated diol alternatives.

The C10H18O4 composition indicates a butynediol core with two propylene oxide units added, yielding a nominal molecular weight of approximately 178.24 g/mol (typical for this propoxylation degree). Standard grades for polyurethane chain extension contain primary hydroxyl content between 95-100% with hydroxyl values typically in the 560-630 mg KOH/g range, though buyers should request the Certificate of Analysis for the specific batch. The material functions as a chain extender that enhances tensile properties and tear resistance in cast elastomers, and as a crosslinking modifier in flexible foam formulations where it improves load-bearing capacity without significant density increase. Compatibility with aromatic and aliphatic isocyanates, including MDI and TDI systems, is well-established in coating and adhesive applications.

Primary buyers include polyurethane foam manufacturers, CASE (coatings, adhesives, sealants, elastomers) formulators, and automotive interior suppliers requiring flame-laminated foam substrates. The material is typically traded in 200 kg drums, IBC totes, or bulk ISO tank containers for volumes above 20 metric tons. Import buyers should confirm moisture content (typically <0.05% standard), acid value, and colour specification (APHA or Gardner scale) with Wuhan Silworld Chemical Co., Ltd. directly, as these parameters affect isocyanate reactivity and final product aesthetics. FOB Shanghai or Ningbo, and CFR terms are common for this commodity chemical, though specific Incoterms require direct confirmation with the supplier.

Wuhan Silworld Chemical Co., Ltd. operates from No.198 Jiangjun Road in Wuhan, Hubei Province, with postal code 430033. The company holds a Harbor trust tier classification on the platform, though its response rate is recorded at 0.00% with zero average response hours, which indicates no historical response data is available through this channel. The supplier's profile does not state founding year, registered capital, production capacity, or specific quality management system certifications, so buyers should request ISO 9001, ISO 14001, or equivalent documentation directly during qualification.

The listing presents Wuhan Silworld Chemical Co., Ltd. as offering Butynediol Propoxylate for industrial polyurethane applications, with emphasis on bulk supply flexibility. No manufacturing site details, R&D credentials, or export licence numbers are provided in the source material. Buyers are advised to verify business licence, dangerous goods handling permits (given the acetylenic alcohol chemistry involved), and previous export references to Europe or North America before committing to volume orders.
