Plan a trial for your application
Heat-resistant flexible PVC
In equal-hardness formulations, compare heat loss, color change on aging and tensile strength retention.
Heat-resistant cable compounds
Evaluate heat aging, volume resistivity and processing stability in the actual insulation compound.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. ENVO · Trioctyl Trimellitate (TOTM) catalogue and specifications ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Acid value | mg KOH/g | ENVO published premium grade ≤0.15 | Define the titration basis. Confirm the main ester identity and method before comparison. |
| Density | g/cm³ | ENVO published premium grade 0.984–0.991 | Measured at 20 °C. Verify the contractual acceptance temperature. |
| Volume resistivity | Ω·m | Agree for the cable compound. | Measure on the actual insulation compound at specified temperature, humidity, thickness and electrode conditions. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Published examples include 200 kg drums and IBCs. Check that unloading equipment can handle the viscosity.
Storage and handling
Monitor colour, moisture and residual contamination by lot. For cable grades, request application-specific test results.
Sample and order lead times
State the finished part, machine trial quantity and routine order size. Match trial and commercial grades and agree MOQ, load unit, lead-time start and arrival.
Questions from the plant
Will hardness and mass hold after heat ageing?
Age at the intended temperature for the relevant duration. For cable applications, also test electrical properties of the finished compound.
Does low volatility establish cable compound compliance?
Check the matrix, residual ions and moisture. Measure electrical performance of the finished insulation compound at the project temperature.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check ester value, volatile loss, volume resistivity test conditions.
