Overview

TCR Engineering tests polymers, rubbers, composites and FRP/GRP materials for mechanical, thermal and environmental performance at its NABL ISO/IEC 17025:2017 accredited laboratory (NABLT0726MH18640) in Navi Mumbai. The bench covers tensile, flexural, compression, impact and hardness testing alongside DSC, TGA, FTIR, filler identification, density, water absorption and FRP/GRP pipe qualification.

Testing of polymers, rubbers, and fibre-reinforced plastics for mechanical and environmental performance. Tensile, flexural, compression per ASTM D638, ASTM D790, ASTM D695. Izod impact on plastics per ASTM D256. Hardness (Shore A, D, IRHD) per ASTM D2240. Thermal properties: glass transition temperature, melting point, coefficient of thermal expansion, TGA, DSC. Environmental: accelerated weathering, UV resistance, heat ageing. FRP/GRP pipe qualification for hydrostatic performance, axial load, and cyclic pressure. ISO 527, ISO 178, ISO 179, ISO 180.

Overview

Mica testing for EV battery thermal insulation was added in May 2026. Tile adhesive testing per IS 15477 (comprehensive shear, pull-off, open time, and slip tests) supports the construction-materials buyer.

Rubber and polymer characterisation also covers compression set and compressive strength on rubber, water absorption, filler content and identification, density, Fourier-transform infrared spectroscopy (FTIR).

At our advanced materials testing lab in India, we offer comprehensive testing services for composites, plastics, and rubber to ensure the quality, durability, and performance of your materials.

Our services include:

  • Tensile Testing (Average of % Specimen): Measures the strength and elongation properties of materials under tension.
  • Shore Hardness Testing (Shore A & Shore D): Determines material hardness levels for both soft and rigid plastics.
  • Differential Scanning Calorimetry (DSC): Analyses thermal properties and stability.
  • Thermogravimetric Analysis (TGA): Measures changes in material weight as it is heated.
  • Fourier Transform Infrared Spectroscopy (FTIR): Identifies chemical bonds in a material.
  • Filler Content & Identification: Determines the percentage and type of filler in materials.
  • Density Testing: Measures material density.
  • Water Absorption Testing: Evaluates material's resistance to water.
  • Compression Set & Compressive Strength Testing: Assesses rubber deformation and compressive strength.

These tests ensure compliance with industry standards and provide insights into material performance for demanding applications.

Standards: ASTM D638, D790, and D695 (tensile, flexural, compression), ASTM D256 (Izod impact), ASTM D785 and D2240 (hardness). ISO 527, ISO 178, ISO 179, ISO 180. IS 15477 (tile adhesive).
