Description

Tri-Isodecyl Trimellitate (CAS NO 36631-30-8) is a high-performance, high-molecular-weight trimellitate ester plasticizer. This compound matters for its exceptional permanence properties, offering superior resistance to extraction and migration compared to standard phthalate plasticizers. It is primarily needed by manufacturers in the polymer industry seeking durable, low-volatility plasticizers for demanding applications, particularly in high-temperature wire and cable insulation, automotive components, and specialty films.

Application

• Primary plasticizer for high-temperature PVC wire and cable insulation and jacketing.
• Key component in automotive interior applications, such as dashboard skins and under-hood components requiring heat and oil resistance.
• Formulation of specialty films and sheets where low volatility and minimal fogging are critical.
• Use in gaskets, seals, and other elastomeric products demanding long-term flexibility and durability.
• Plasticizer for coated fabrics and tarpaulins that require weather and water resistance.
• Formulation of adhesives and sealants requiring permanent plasticization and compatibility with various polymers.
