FAQ - Technical & Supply Chain
-
Q:
Is Di-n-octyl Adipate the same as Bis(2-ethylhexyl) Adipate?
A: No. Di-n-octyl adipate under CAS 123-79-5 is the straight-chain n-octyl ester. Bis(2-ethylhexyl) adipate, often also called DOA, is CAS 103-23-1 and has branched ester groups. The full chemical name and CAS number are essential when comparing plasticizer offers. -
Q:
Which release specifications matter for Di-n-octyl Adipate?
A: Agree ester assay and method, acid value, water, color, density, refractive index, viscosity, flash point and specified ester-related impurities. Low-temperature plasticizer use may also require a defined pour point or cold-flexibility qualification. Review the batch COA against the intended formulation specification rather than approving a generic DOA name.
