Resonance PL91-203_D is a medium functionality aromatic polyether polyol that is delivered in clear liquid form.
Hydroxyl type | Primary aliphatic |
Polyol functionality | Nominal 2.6 |
Delivery form | Clear liquid |
Resonance PL91-203_D is suitable for all polyurethane rigid foam applications such as flexible faced insulation, insulated metal panels and spray polyurethane foams.
Resonance PL91-203_D polyol is reactive with isocyanate, has high aromaticity and exhibits higher functionality than a typical aromatic polyester polyol.
Resonance PL91-203_D polyol is designed to be used in formulated polyol blends for rigid polyurethane foam applications. The polyol is designed to enhance the aromaticity of polyol blends for improved reaction to fire and insulation thermal conductivity. The product is 100% ethylene oxide capped and exhibits good reactivity.
