Trial design and interpretation

Require chemical name, CAS number and destination-market documents and check them against the sample label. Resolve ambiguous trade abbreviations with each supplier before comparing costs.

Recording Density at 20 °C

Density at 20 °C (g/cm³): ENVO listing for CAS 117-81-7: 0.983–0.985. Applies only to bis(2-ethylhexyl) phthalate. Verify identity and temperature before use. Assay (% by mass): ENVO CAS 117-81-7 listing ≥99.5. State the chromatographic or other assay basis.

Do two offers marked DOP identify the same ester?

Request the full chemical name, CAS, SDS and COA for each. Match identities before comparing price and PVC trials. Flexible PVC compounding: Keep resin and plasticizer loading fixed. Compare fusion time, hardness and tensile properties.
