Thermal and impact instruments for rubber and thermoplastics — softening point, heat deflection, oxidation induction and ash content — to ASTM and ISO methods.

Rubber and engineering thermoplastics are judged on how they hold up under heat and stress: the temperature at which they soften or deflect, how long they resist oxidation, and how much residue remains on combustion. These properties predict service life and processing behaviour.
International Equipments builds this thermal and impact group in-house in Mumbai and exports it to 50+ markets, each instrument mapped to the relevant ASTM/ISO method, CE marked and calibration-certified.
Each machine links to full technical specifications, models and standards.
