- Genuine Wanhua material only
- Wanhua COA and TDS with every batch
- Shipped from Dubai or Qingdao
- One consistent specification, order after order
Polyols
Polyols are the backbone of every polyurethane — they set the flexibility, durability and performance of the finished product.
Polyether polyols
Flexible foamExcellent hydrolytic stability and easy processing.
- High resilience
- Low viscosity
- Broad isocyanate compatibility
Used in: Furniture foam, mattresses, car seats, sponges, packaging foam
Polyester polyols
Rigid & elastomersHigher rigidity, abrasion and chemical resistance, with strong tensile strength and thermal resistance.
- Rigid foam applications
- Shoe soles
- Coatings & adhesives
Used in: Rigid foam, shoe soles, coatings, adhesives, flexible moulded foam
Isocyanates
TDI and MDI react with polyols to build the polyurethane network. Choose by end use: TDI for flexible foam, MDI for rigid insulation and CASE.
TDI 80/20
Flexible foamAromatic isocyanate blend of 80% 2,4-TDI and 20% 2,6-TDI with excellent reactivity for high-volume foam production.
Used in: Flexible slabstock and moulded foam
Polymeric MDI
Rigid foamHigh thermal insulation and good flow properties.
Used in: Insulation panels, refrigeration, spray foam
Monomeric MDI
SpecialtyPure MDI for applications needing precision and high-performance bonding.
Used in: Specialty systems and elastomers
Prepolymeric MDI
Adhesives & sealantsModified MDI with better workability and extended pot life.
Used in: Adhesives, sealants, elastomers
Catalysts, surfactants & additives
The additives that control reaction speed, cell structure, fire performance and colour.
Amine catalysts
Reaction controlControlled reaction rates, foam stability and better surface quality.
Used in: Slabstock, rigid panels, moulded automotive parts
Stannous octoate
Metal catalystAccelerates urethane formation and works alongside amine catalysts for precise processing control.
Used in: Flexible polyurethane foam
Silicone surfactants
Cell structureRigid grades give fine closed cells and dimensional stability; HR and viscoelastic grades give flow, comfort and uniformity.
Used in: Rigid, HR moulded and memory foam
Blowing agents
ExpansionPhysical and chemical agents for uniform cells, low thermal conductivity and lower density.
Used in: Refrigeration insulation, spray and moulded foam
Flame retardants
Fire safetyImproved fire resistance in line with global fire-safety standards.
Used in: Furniture, construction and automotive foams
Foam hardener
Load bearingRaises density and hardness without changing formulation ratios.
Used in: Rigid and high-load-bearing foams
Colorants
Liquid & pasteUV-resistant, non-bleeding, heat-stable colours compatible with PU systems.
Used in: Automotive interiors, footwear, specialty foam
Bio-based & raw materials
Castor oil
RenewableA natural, renewable raw material for eco-friendly polyurethane systems.
