PINE-POL™ A220: Due to the rigid structure of one of the most common pine chemicals – rosin – rigid foam applications are a natural fit for Lawter’s biopolyols. PINE-POL™ A220 was developed as a drop-in replacement for petroleum-based polyols in polyisocyanurate (or PIR, polyiso) foam commonly used in the construction industry. Including A220 increases bio renewable content and reduces carbon footprint without compromise to PIR foam properties.
PINE-POL™ B-series: Pine chemicals are also ideal for rigid polyurethane (PUR) foam applications such as spray and appliance foams, where dimensional stability, thermal resistance, and reaction kinetics are critical. The PINE-POL™ B-series biopolyols are miscible with a wide range of chemistry, have a high functionality with reasonable viscosity, and the kinetics can be easily tuned to meet system needs via tweaks to the catalyst package.
Biopolyols for flexible foam
PINE-POL™ F-Series: Pine chemistry is also ideally suited for flexible foam polyols. Many of the foams used daily by consumers are flexible polyurethane foams (e.g. mattresses, pillows, furniture cushions) and there is growing demand for bio-based foams in these applications. PINE-POL™ F-series polyols offer unique technical properties for such flexible foam types as viscoelastic, high resilience, and conventional. They are a novel formulation tool for maximizing % bio renewable content in a flexible foam, and also offer unique properties to foam, regardless of whether bio renewable content is of interest.
