Grupo RB’s pentaerythritol rosin esters are high-performance tackifying resins that offer customers high-quality formulation tools for glues, hot-melt adhesives, pressure-sensitive adhesives, and depilatory waxes. Having excellent compatibility with natural and synthetic resins and a higher softening point than glycerol esters, they are an ideal choice for various formulations and can also be used as a substitute for hydrocarbon, aromatic, or aliphatic resins.
