Plastic ball indentation hardness tester

Meet the standard:

ISO 2039-1

Product Introduction:

The hardness of plastics is a fundamental property that influences their performance, durability, and suitability for various applications, from consumer goods to industrial components. Indentation hardness, specifically measured by the ball indentation method, provides a valuable metric for assessing a plastic's resistance to local deformation and its elastic recovery characteristics.

This Plastic Ball Indentation Hardness Tester is designed to accurately perform tests according to recognized international standards, such as ISO 2039-1. The testing process involves applying an initial preload (9.8 N) to set a reference point, followed by a specific test load (selectable from 49N, 132N, 358N, 961N) for a defined period (10-90 seconds). The instrument utilizes hardened steel ball indenters of specified diameters (5mm and an optional 10mm) to press into the surface of the plastic sample. The indentation depth is precisely measured with a high resolution of 0.001mm, allowing for accurate calculation of the material's indentation hardness value. 

The instrument is used in laboratories for:

Determining the ball indentation hardness of various plastic materials.

Assessing the resistance of plastics to permanent deformation under load.

Evaluating the hardness characteristics of rigid and semi-rigid plastics.

Quality control of plastic raw materials and finished products.

Research and development of new plastic formulations with specific hardness requirements.

Ensuring compliance with international standards for plastic hardness testing.

Material selection based on hardness properties for specific applications.
