Polymers Testing Equipments — Complete Range of Laboratory Instruments for Engineering Plastics, Master-batch, Compounding & Speciality Polymer Quality Control

★ CLIENT USING THIS MODEL

International Equipments is one of India's leading manufacturers, suppliers and exporters of laboratory Polymer Testing Equipments — covering the complete range of instruments needed for the quality control, grade qualification, R&D and failure analysis of engineering plastics, master-batch, compounded polymers, speciality polymers and composites. Built at our Mumbai facility since 1971 and exported to over 50 countries, our polymer testing instruments are installed in the QC and R&D laboratories of polymer producers, master-batch compounders, engineering plastic moulders, automotive component manufacturers, defence and ordnance establishments, and premier polymer research institutions including CIPET.

Polymer testing is the most R&D-intensive of our testing-equipment categories — it serves not just routine production QC but also the demanding requirements of polymer grade development, new compound qualification, composite material characterisation and advanced materials research. Our polymer testing instruments measure the full spectrum of polymer properties: melt flow behaviour, mechanical strength and toughness, thermal performance (softening point, heat deflection, oxidation stability), environmental stress cracking resistance, density and compositional makeup. We supply the complete polymer-testing instrument range from a single Mumbai facility.

About Our Polymer Testing Equipment Range

Equipment for testing Master batch, Engineering plastics, Compounding and Speciality polymers such as PE-KK (Poly Ether-Ketone-Ketone), SAN (styrene Acrilo-Nitrile) and composites such as Poly Carbonate, ABS, Poly Styrene, Thermo plastic resins, Amides and thermoplastic Elastomers, PE, Nylon, Rigid PVC, PP with glass filled, Medium Density poly ethylene (MDPE), High density poly ethylene (HDPE) and various different material testing.

What are Polymer Testing Equipments?

Polymer testing is the systematic laboratory measurement of a polymer's mechanical, thermal, physical, rheological and chemical properties — to characterise the polymer for quality control, grade qualification, R&D development or failure analysis. While closely related to plastic testing and material testing, polymer testing carries a particular emphasis on the science of the material itself: measuring how molecular weight, crystallinity, filler content, additive loading and processing history affect the polymer's behaviour. This makes polymer testing the natural domain of polymer producers, master-batch compounders, R&D laboratories and academic / research institutions.

The polymer materials tested span an enormous range — from commodity polyolefins (PE, PP, HDPE, MDPE) through engineering plastics (ABS, PC, PA/Nylon, POM, SAN) to high-performance speciality polymers (PEKK and other PEEK-family polymers) and fibre-reinforced composites (glass-filled PP, glass-filled nylon). Each material family has its own characteristic property profile and its own testing requirements. Our instrument range — built specifically for the load ranges, temperature ranges and sample geometries relevant to polymer materials — covers the testing needs across this complete spectrum.

Polymers & Composites We Help You Test

Commodity Polyolefins (PE, HDPE, MDPE, PP)

Polyethylene (PE), High-Density Polyethylene (HDPE), Medium-Density Polyethylene (MDPE), Polypropylene (PP) — the high-volume commodity polymers used in packaging, pipes, containers and consumer products. Tested for MFI, density, tensile, impact, OIT (for HDPE/MDPE pipe grades), ESCR and ash content.

Engineering Plastics (ABS, PC, PA/Nylon, POM, SAN)

Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Polyamide/Nylon (PA), Polyoxymethylene (POM), Styrene Acrylonitrile (SAN) — the higher-performance engineering plastics used in automotive, electronics and durable goods. Tested for tensile, flexural, Izod/Charpy impact (critical for engineering plastics), VSP/HDT, MFI, density and moisture (for hygroscopic grades like PA, PC, ABS).

Speciality & High-Performance Polymers (PEKK, PEEK family)

Poly Ether-Ketone-Ketone (PEKK) and the broader PEEK family of high-performance semi-crystalline thermoplastics — used in aerospace, medical implants, oil-and-gas and demanding engineering applications. Tested for high-temperature mechanical properties, VSP/HDT (these polymers have very high softening points), thermal stability and density.

Thermoplastic Elastomers (TPE, TPV)

Thermoplastic Elastomers and Thermoplastic Vulcanisates — combining rubber-like flexibility with thermoplastic processability. Tested using both plastic methods (MFI, tensile) and rubber methods (ASTM D 412 tensile, heat ageing).

Glass-Filled & Fibre-Reinforced Composites

Glass-filled PP, glass-filled nylon (PA-GF), and other fibre-reinforced polymer composites — where glass fibre dramatically increases stiffness and strength. Tested for tensile and flexural strength (much higher than the base polymer), Izod/Charpy impact, HDT (significantly elevated by glass fill), ash content (to verify the glass-fibre loading percentage via the Muffle Furnace).

Master-Batch & Compounded Polymers

Colour master-batch, additive master-batch, filler master-batch and fully-compounded polymer grades — where pigments, additives, fillers and modifiers are blended into a base polymer. Tested for MFI (to verify compound consistency), density, ash content (filler loading), dispersion quality and the mechanical/thermal properties imparted by the compound.

Rigid PVC, Styrenics & Other Thermoplastic Resins

Rigid (unplasticized) PVC, Polystyrene (PS), and the broad family of thermoplastic resins and amides. Tested for VSP (critical for rigid PVC), tensile, impact, MFI and density.

Categories of Polymer Testing Instruments We Manufacture

Polymer testing instruments fall into five broad categories. A complete polymer testing laboratory typically needs instruments spanning all five:

Rheological Testing (Melt Flow)

The Melt Flow Index Tester characterises the molten-polymer flow behaviour — the single most-used polymer QC measurement, directly correlating with molecular weight and processability. Available in Manual, Auto-cut and Computerised variants. The gatekeeper test for every incoming polymer batch and the primary grade-consistency check.

Mechanical Testing (Tensile, Flexural, Impact)

The Universal Testing Machine and Single-Screw Tensile Testing Machine measure tensile, flexural and compression properties. The Izod / Charpy Impact Tester measures impact toughness — particularly critical for engineering plastics and glass-filled composites where impact behaviour is a key design property. The Motorized Notch Cutter and Micro-meter Jig prepare and verify impact specimens.

Thermal Testing (VSP, HDT, OIT, Ash)

The VSP / HDT Apparatus measures Vicat Softening Point and Heat Deflection Temperature — defining the maximum service temperature of the polymer (especially important for engineering plastics and high-performance polymers). The OIT Apparatus measures oxidation stability. The Muffle Furnace measures ash / filler content. The Hot Air Oven provides conditioning and ageing.

Environmental & Physical Testing (ESCR, Density, Moisture)

The ESCR Apparatus measures environmental stress cracking resistance (critical for HDPE grades). The Digital Density Apparatus measures density (verifies composition and filler loading). The Moisture Analyser measures moisture content (essential for hygroscopic engineering polymers like PA, PC, ABS before processing).

Sample Preparation

The Hydraulic Press (with ASTM/ISO cutting dies) and Contour Cutter produce dimensionally-accurate test specimens; the Motorized Notch Cutter adds the standard notch for impact specimens. Reliable polymer test results depend on correctly-prepared specimens.
