Pentaerythritol Tetrabenzoate (Cat No.:L045462) is an ester-based plasticizer primarily used to improve the flexibility, durability, and thermal stability of polymers such as PVC. It is a white, crystalline, non-volatile compound known for its low migration and excellent compatibility with resins. Due to its high molecular weight and aromatic content, PETB enhances flame resistance and mechanical properties in coatings, adhesives, and sealants. Its non-toxic nature and resistance to weathering also make it suitable for medical and cosmetic formulations, offering both performance and environmental benefits in specialty applications.
