Suzhou TreeUp Chemical Co., Ltd. has spent 13 years exporting polyurethane raw materials from China. We supply TDI, polyether polyol PPG, POP, MDI and the full range of PU additives — supported by four bonded warehouses and container loading out of Shanghai, Ningbo and Shenzhen.
Indicative FOB China main port ranges, updated 21 Oct 2026. Export tax rebate and port charges are included in the ranges; final terms are confirmed per order and subject to market movement.
More than a supplier — an export partner covering sourcing, warehousing, documents and vessel schedules
Long-term purchase contracts with Wanhua Chemical, Cangzhou Dahua and BASF secure both pricing and allocation.
Regular grades are stocked in Shanghai, Ningbo, Nantong and Qingdao bonded zones; containers loaded within 72 hours.
Our application lab provides free samples, cell-structure analysis and formulation tuning to cut your total material cost.
Licensed for dangerous goods export, with REACH support letters, UN-approved packaging and a full document set.
TDI, PPG, MDI and the full additive package — drums, IBC or ISO tank
Available as TDI 80/20, TDI 65 and TDI 100. Purity ≥ 99.6%. For flexible slabstock foam, coating hardeners and prepolymers.
Learn more →Slabstock, rigid, CASE and amine-terminated grades. Molecular weight 300 – 6000, hydroxyl value customised on request.
Learn more →SAN-grafted polyol that raises foam hardness and load-bearing behaviour. Used in HR, viscoelastic and moulded foam.
Learn more →Polymeric, modified and liquefied MDI for appliance insulation, PIR panels, adhesives and shoe sole systems.
Learn more →Silicone surfactants, amine and tin catalysts (A33 / T-9 / T-12), flame retardants, pigments, release agents and odour removers.
Learn more →Propylene glycol, dipropylene glycol, glycerine, NMP and DMC — serving cosmetics, flavours, pharma and animal health.
Learn more →From a piece of foam to an insulation panel — our raw materials end up everywhere
Built on our PPG and TDI supply strength, we deliver consistent resilience and support for premium mattresses, memory pillows, sofas and automotive seating.
Prepolymers and CASE-grade polyols for casters, rollers, seals and polyurea coatings, delivering outstanding tear strength and abrasion resistance.
Polymeric MDI paired with high-functionality rigid polyol gives low thermal conductivity and excellent dimensional stability for cold rooms and facade insulation.
TDI adducts and trimer hardeners combined with low-unsaturation polyols balance hardness, flexibility and weather resistance.
