Tris-(2-ethyl-1-hexyl)-1,3,5-cyclohexantricarboxylat, also known as Tri-(2-ethylhexyl) trimellitate (TEHTM), is a high molecular weight ester plasticizer derived from cyclohexane-1,2,3-tricarboxylic acid and 2-ethylhexanol. It is characterized by its excellent low temperature flexibility, resistance to extraction, and low volatility, making it suitable for use in various applications such as PVC, adhesives, sealants, and coatings. TEHTM is known for its good compatibility with polymers, providing improved mechanical properties and durability. It is also recognized for its low migration properties, which is beneficial for applications where resistance to migration is critical, such as in food packaging and automotive interiors.
The CAS Registry Mumber 67208-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,0 and 8 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 67208-88: (7*6)+(6*7)+(5*2)+(4*0)+(3*8)+(2*8)+(1*8)=142 142 % 10 = 2 So 67208-88-2 is a valid CAS Registry Number.
