TDI and MDI across all grades — Chinese and imported origins
An 80:20 blend of the 2,4 and 2,6 isomers. The workhorse isocyanate for flexible polyurethane foam with a wide processing window.
Request quote →Pure 2,4-isomer and a 65:35 blend for coating hardeners, cast elastomers and speciality prepolymer synthesis.
Request quote →The standard black component for appliance insulation, building panels and spray rigid foam.
Request quote →PPG / POP / CASE polyols / amine-terminated grades — molecular weight and functionality on request
Trifunctional high-reactivity polyol, OH value 54 – 56 mgKOH/g. Uniform cell structure and good resilience — the standard white component for slabstock.
Request quote →SAN-grafted polyol with stable solids content. Raises foam hardness, IFD and open-cell behaviour.
Request quote →High-functionality polyol combined with PMDI delivers dimensional stability and low thermal conductivity for panels and spray foam.
Request quote →Low-unsaturation, narrow-distribution polyol for adhesives, sealants, coatings and elastomers — flexible and hydrolysis resistant.
Request quote →From 1 kg, repacking available — ideal for formulation trials
Grades such as L-580 and B-8110 stabilise cell structure and prevent collapse or shrinkage, with matched types for flexible and rigid foam.
Request quote →A33 (DABCO), T-9 stannous octoate and T-12 DBTDL — balancing the blowing and gelling reactions precisely.
Request quote →Eco-friendly phosphorus flame retardants, water-based release agents and universal PU pigments. Solutions for BS 5852 and CA 117 available.
Request quote →Serving cosmetics, flavours, pharma and feed industries
Industrial and food grades. Used as humectant, solvent and UPR feedstock. Low odour, consistent purity.
Request quote →99.5% refined and 95% industrial grades for cosmetics, flavour carriers, tobacco humectants and veterinary formulations.
Request quote →A strong polar aprotic solvent for lithium batteries, electronics cleaning, resin synthesis and agrochemical intermediates. Low moisture, low free amine.
Request quote →Part of our regular stock range. Custom specifications on request
