Test data only means something when the comparison is fair: the same base formulation, the same process, and the same conditioning method, with and without the compatibilizer. Organized into five blocks, each test block answers a specific decision question.
Raw material
Measure appearance, MFR / MFI, grafting ratio, and density.
Decision question: is the grade within the agreed incoming-control window?
Processing
Track torque, melt pressure, output, surface, and die build-up.
Decision question: can the compound run stably without hidden process cost?
Mechanical
Measure tensile strength and elongation at break.
Decision question: did the interface improvement preserve the target mechanical balance?
Durability
Run thermal aging and record retention of tensile and elongation.
Decision question: is the improvement stable after heat exposure?
Cable-specific
Apply flame, smoke, acidity, hot-set, or electrical tests as the cable design requires.
Decision question: does the final compound meet the customer specification?
Applicable cable tests depend on cable design and customer standard. Numbers without stated test conditions are not evidence — always report the full method alongside the result, and never claim IEC / UL performance without a traceable test report.
