The main cause of any material like paper and thermoplastic films getting torn is through snag and pull. The initial hole is small, but if these materials will be pulled further, the hole can become much larger. Thus, testing the tearing strength of paper is important to make sure that the right quality of material has been delivered to the customers. Thus, we at Presto have come up with one of the amazing lab testing instruments known as the tearing strength tester. This is a widely used testing instrument that is helpful in determining the tearing strength of paper and plastic films under controlled test conditions. Here in this blog, we are going to provide you the information about the installation of a tearing strength tester and how this lab testing instrument is useful in determining the tearing strength of paper and plastic films. So, let us get started!
Introduction about tearing strength tester
Tearing strength is an important factor to consider when testing the quality of materials. The Presto Elmendorf tearing strength tester is a reliable and easy-to-use lab testing equipment for testing the tearing strength of various materials. The tearing strength testing machine is highly useful in measuring the internal tearing resistance of materials. This force is perpendicular to the plane of the paper when propagating a single rip or tears by measuring the force required to continue the slit previously cut in the material. The Presto tearing strength tester can be used to test a variety of materials, including paper, textiles, and plastics. With this tester, you can quickly and easily determine the tearing strength of your material, and ensure that it is up to par.
Below we have listed the features of the Presto tearing strength testing machine.
- The unit of measurement is “mN” i.e. mega newton.
- The laboratory equipment comprises a falling pendulum to cover various angles.
- The instrument is supplied with cutting templates, a board, and a cutting knife for preparing a sample for the test.
- There is a start and stop functions to hold the pendulum for safety.
- The test parameters include peak load, median load, and tearing strength.
- The procedure is done to determine tearing strength that involves a cut in the center. An opposing tail, known as the “tongue” is duly clamped in the instrument.
- High-Quality rugged structure with the corrosion-resistant main body
- Falling pendulum-type instrument
- Single-handed hassle-free operation
- Highly accurate test results under multiple pendulum weights
- Strong gripping fixture for holding test samples
- Pendulum release mechanism to cover the various measuring range
- Inbuilt calibration weights
