Plasticizers

Plasticizers increase polymer chain mobility, lowering glass transition temperature, and enhancing flexibility without compromising adhesion strength. Plasticizers prove essential in applications in construction sealants, pressure-sensitive adhesives, and assembly applications. 

Sub-types include adipates, benzoates, citrates, and polymeric plasticizers. Recent developments focus on bio-based plasticizers derived from renewable resources like vegetable oils and growing demand for non-phthalate plasticizers addressing regulatory concerns.
