Rosins & Derivatives
Pentaerythritol Ester of Rosin
Higher softening point, broader compatibility.
Pentaerythritol ester providing improved heat resistance and adhesion in hot-melt and pressure-sensitive adhesive systems. The four-functional alcohol crosslinks more rosin acids per molecule than glycerol, lifting the softening point by ~15 °C over conventional ester gum.
