Common questions about polyurethane raw materials and our supply capabilities
Q: What is Polyether Polyol used for?
A: Polyether polyol is widely used for polyurethane foam production including rigid foam insulation for buildings and appliances, flexible foam for furniture and automotive seating, and integral skin foams for various industrial applications.
Q: What is the difference between MDI and TDI?
A: MDI (Methylene Diphenyl Diisocyanate) is primarily used for rigid foam insulation and structural applications requiring high strength. TDI (Toluene Diisocyanate) is mainly used for flexible foam production such as furniture cushioning, automotive seats, and carpet underlay.
Q: What is your minimum order quantity (MOQ)?
A: MOQ varies by product type. For bulk chemicals like Polyol and MDI, typical MOQ starts from one full container load (FCL). For additives and specialty products, smaller quantities may be available. Please contact our sales team for specific product MOQ details.
Q: Do you provide technical documentation?
A: Yes, we provide comprehensive Technical Data Sheets (TDS), Material Safety Data Sheets (MSDS), and Certificates of Analysis (COA) for all products. These documents are available upon request or can be downloaded from our product pages.
Q: How do you ensure product quality?
A: All our partner manufacturers are ISO9001 certified. We implement strict quality control procedures with batch traceability. Every shipment comes with a Certificate of Analysis (COA) verifying product specifications meet international standards.
