Buy Carbon Black Dispersion Tester directly from the manufacturer. No middlemen — best price and fastest support in Kolkata.
Every Carbon Black Dispersion Tester comes with a factory calibration certificate. NABL calibration available on request.
Our engineers visit your lab in Kolkata for installation, commissioning and operator training.
Complies with ISO 18553, ASTM D5596, IS 12235 — accepted by QC labs and export testing facilities.
Carbon black dispersion testing evaluates how evenly carbon black particles are distributed through the polyethylene matrix, using optical microscopy. Thin microtomed sections of the pipe or compound are examined under a microscope and compared against standard reference charts to assign a dispersion grade (A to E) per ISO 18553. Good dispersion is essential — even with correct carbon black content, poorly dispersed agglomerates create weak points that shorten pipe life.
Every HDPE pipe and fitting manufacturer, and every masterbatch producer supplying carbon black masterbatch, must demonstrate acceptable dispersion to ISO 18553, ASTM D5596 and IS 12235. The test complements carbon black content testing and is required for BIS certification of pressure pipe.
The essential equipment is a good-quality optical microscope with the correct magnification, a microtome to prepare thin sections, and the ISO 18553 reference charts for grading. International Equipments supplies carbon black dispersion microscopy systems configured for pipe-industry compliance testing.
Kolkata and the industrial centres at Durgapur, Kalyani and Howrah form eastern India's hub for jute-polymer blends, woven-sack manufacturing, pipe production and rubber goods. The strong woven-sack and packaging sector creates particular demand for tape tensile, fabric bursting-strength and yarn testing, while pipe producers need hydrostatic-pressure and carbon-black testing. International Equipments supplies and supports the full range of textile, polymer and pipe testing instruments across West Bengal and the eastern region.
As a direct manufacturer rather than a reseller, International Equipments offers customers in Kolkata a distinct advantage: you deal directly with the company that designs and builds the Carbon Black Dispersion Tester, so pricing is competitive, lead times are shorter, and technical questions are answered by the engineers who actually build the instrument. Whether you are setting up a new quality-control laboratory in Durgapur, Kalyani, Howrah, Taratala or upgrading existing equipment, our team can recommend the right Carbon Black Dispersion Tester configuration for your materials, standards and throughput, and support it with installation, operator training and periodic calibration.
Kolkata and Durgapur serve as eastern India's hub for jute-polymer blends, woven sack manufacturing and pipe production. The demand for Carbon Black Dispersion Tester in Kolkata comes from Jute-polymer blends, Woven sacks, Pipe manufacturing industries in Durgapur, Kalyani, Howrah, Taratala.
