Resonance™ PL91-203_D

Description

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 

Application

Resonance PL91-203_D is suitable for all polyurethane rigid foam applications such as flexible faced insulation, insulated metal panels and spray polyurethane foams. 

Benefits

Resonance PL91-203_D polyol is reactive with isocyanate, has high aromaticity and exhibits higher functionality than a typical aromatic polyester polyol. 

  • Eliminate or reduce aliphatic polyether polyols
  • Improve reaction to fire or reduce fire-retardant additives
  • Maintain mechanical properties such as dimensional stability when replacing high functionality aliphatic polyether polyols
  • Compatible with several commonly used fire retardants, polyols and blowing agents including HFOs
  • Water resistant

Product Features

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.
