TOTM and DOA: selecting plasticizers for temperature requirements
TOTM and DOA address different selection goals.
TOTM and DOA address different selection goals. TOTM is a trimellitate considered for high-temperature PVC applications where low volatility is needed. DOA is an adipate considered for low-temperature flexibility. Classifying DOA simply as a high-temperature plasticizer would therefore be misleading.
A comparison plan
Define the service-temperature range and ageing duration first. For hot conditions, assess mass loss, hardness and mechanical changes; for cold conditions, use the relevant flexibility or brittleness test. Validate blends within the complete formulation. Request the current grade-specific TDS for TOTM, DOA or polymeric plasticizers rather than relying on a universal temperature rating.

Optafleks TOTM — TOTM high-temperature plasticizer
Assess long-term heat ageing, mass loss and retention of mechanical properties together. TOTM viscosity may affect processing and mixing conditions. The raw material's flash point is not the continuous service temperature of the finished PVC article; validate temperature ratings through finished-product tests.

Evaluate cold flexibility alongside migration and volatility targets when selecting DOA. Use alone or with other plasticizers depends on the formulation. Validate low-temperature performance through cold-bend and mechanical tests on the intended finished article.
