In-House Formulation Depth
What Goes Into a Blended Polyol System
We do not resell drums. Every component below is formulated and blended in-house, which is why the same core chemistry can range from stiff insulation to soft cushioning.
Polyol
Polyether & polyester polyols blended to your target OH value and reactivity.
Catalyst
Amine and metal catalysts tuned for cream, gel and rise-time control.
Surfactant
Silicone surfactants for cell structure, flow and surface quality.
Flame retardant
Reactive and additive FRs to reach your fire-rating targets.
Your blended polyol system
One drum, formulated to your spec — the ready-to-run polyol side (our component A).
Pair it with the matching isocyanate — MDI or TDI, our component B — and you have a complete two-component system ready for your line.
Applications & Industries
Trusted Globally Across Cold Chain, Automotive & Construction Industries
Our blended-polyol systems go into insulated panels, vehicle interiors, building insulation and industrial parts shipped worldwide.
Cold Chain
Cold Chain & Refrigeration
Insulated panels, cold rooms and refrigerator cabinets live or die on lambda and closed-cell content. Our rigid systems hold λ ≤0.020–0.024 W/(m·K) with even density across the full panel cross-section.
Automotive
Automotive & Transportation
Seat cushions, backrests and headrests need resilience and comfort that survive years of use — plus self-skinned parts for armrests and steering wheels moulded straight out of the tool.
Construction
Construction & Insulation
Two-component spray systems for roofing, walls, tanks and pre-insulated pipe — water-blown, closed-cell and applied on site at 1200–1700 psi.
Furniture & Industry
Furniture, Bedding & Industrial Parts
Mattresses, pillows and sofa cushioning from high-resilience systems — alongside solid cast elastomers for wheels, rollers, sieve plates and wear parts.

FAQ
Frequently Asked Questions
Quick answer: A blend polyol supplier formulates and blends the polyol side (component A) of a two-component polyurethane system — base polyol, catalyst, silicone surfactant, blowing agent and flame retardant — which reacts with an isocyanate (component B, MDI or TDI) to form finished foam. Quality is verified against recognised methods such as ISO 845 (apparent density) and ASTM D1622 (rigid cellular plastics density). BlendPolyol has run its own polyol-blending plant in Wuxi, China since 2010, with in-house formulation, batch Certificates of Analysis and REACH-compliant export documents. For ground stabilization and slab-jacking (concrete lifting / void filling), we also blend an injection-grade closed-cell polyol at ≥ 30 kg/m³ free-rise density — see our slab jacking material guide. In short: rebound/settlement resistance for slab-jacking foam comes from the formula (closed-cell content ≥90%, compressive modulus ≥8 MPa) — not just a headline density figure.
