Description

Bis(3,3,5-Trimethylcyclohexyl) Phthalate is a high-molecular-weight, non-phthalate plasticizer known for its excellent permanence and low volatility. This compound is valued for its ability to impart superior flexibility, durability, and resistance to extraction in demanding polymer applications. It is primarily required by manufacturers of high-performance PVC, synthetic rubbers, and specialty polymer compounds seeking enhanced product longevity and stability.

Application

• Primary Plasticizer for PVC: Used in the formulation of flexible PVC products requiring high-temperature resistance and low migration, such as automotive interiors, wire and cable insulation, and coated fabrics.
• Synthetic Rubber Compounding: Acts as a processing aid and plasticizer in nitrile rubber (NBR), chloroprene rubber (CR), and other elastomers to improve low-temperature flexibility and elongation.
• Specialty Polymer Additive: Employed in polyurethanes, acrylics, and other polymer systems to modify flexibility and reduce brittleness in finished goods.
• Adhesive and Sealant Formulations: Enhances the workability and final properties of solvent-based and hot-melt adhesives and sealants.
• Coating and Ink Resins: Imparts flexibility and adhesion in certain industrial coating and printing ink formulations.
