Test The Resistance Of Polymers To Environmental Stress Cracking

Stress cracking is the major problem that is experienced by polymers when they are subjected to different environmental conditions. The environmental factors like rain, sunlight, air result in the crazing in the polymers and when this get combined with the mechanical stress, the polymers experience cracks on the surface of the material and many similar issues. This is known as environmental stress cracking. It is quite different from the polymer degradation as it does not affect the strength of the polymeric chains. Due to these cracks, the quality of the material gets affected.  Environmental stress cracking is a major issue especially in the case of the amorphous polymers as compared to that of semi-crystalline and crystalline polymers. 

How can the effect of ESC on Polymers be studied?

It is quite impossible to explore the impact of ESC on the polymers by creating different environment but the behavior of the polymers under different environmental conditions can be studied on the basis of the roughness of the surface, molecular structure, chemical bonding, the crystalline structure of the polymers, etc. One of the theories of the environmental stress explains that the liquid in the form of rain or acid on the polymeric material can hamper the quality of the polymers and creates cracks on the facade of the material. The cracking of the material due to environmental stress can be a major threat to safety. Therefore, it is necessary to test the effect of ESC on the polymers before using it for any particular application.

ESCR Tester – To Judge the Effect of Environmental Conditions on Polymers

Presto designs and manufactures premium quality of Environmental Stress Cracking Resistance Tester. The instrument is intended to test the resistance of the polymers to environmental stress cracking by replicating the real environmental conditions. The instrument offers highly accurate test results.

Assure Quality Of Products With Laboratory Testing Equipment

The manufacturers in different production units usually consider material testing as the last step which is irrelevant. The quality testing the essential phase in all production houses that must be commenced from very first stage i.e. raw material inspection till it reaches the hands of the customers because the quality of the manufactured goods depends on the material as well as on the production process. For example, if the quality of the raw material which is used for the production process is not up to the mark, then the quality of the end product will definitely get affected, and the efforts to produce that product will be of no use. This wastes not only the time but also the cost and efforts. Therefore, to ensure the quality of the final good, it is necessary to ensure to commence the quality check process from the initial stage of manufacturing so that the strength, quality and other properties of the products can be determined efficiently.

How to test the quality of the products?

The quality of the products can be tested easily with the help of Laboratory Testing Equipments. These equipments offer the modern way to analyze the mechanical properties, behavior, and quality of the materials. These instruments are used in different production verticals to detect the quality flaws and to enhance the quality of the end products. Therefore, it can be concluded that the lab testing machine plays a significant role to improve the quality of the products.

Presto Stantest offers a broad range of laboratory testing equipment for various production verticals. 

Test The Resistance Of Rubbers To Crack Efficiently

Rubbers are used in numerous applications to produce a different type of rubber products. Rubber components have the ability to bear frequent flexing without initiating the cracks as they are highly elastic in nature. The flexing property of the rubber is quite important to judge mainly when a manufacturer needs to use such kind of products in different circumstances where they have to tolerate continuous flexural forces. The De-Mattia Flex Tester is the best and widely used testing machine which is used to measure the resistance of rubber products to cracks which are initiated on the materials either by bending or by extending the sample under different conditions. The testing device is provided to measure the crack formation in rubber when placed under continuous flexing conditions.

Best Method Introduced by Presto for Rubber Testing

Presto Stantest, a foremost manufacturer of rubber testing machine, offers high quality of De-Mattia Flex tester to test the quality and strength of the rubbers. The testing machine produces continuous flexing with a particular condition of mode, degree and speed of flexing in the testing laboratories on a sample of the rubber.

How can the De-Mattia Flex Tester be operated?

The testing instrument provides full-fledged information regarding the resistance of the vulcanized rubbers to cracking when placed under repeated flexing. The cracks in the samples are developed on the rubbers where the stress is applied on the materials when they are placed under continuous flexural forces. If the specimen is already cracked from a particular area, more cracks are developed, or the cracks are enhanced in opposite direction. The testing machine is used to test at least six samples simultaneously. The device is provided with digital control panel and counter that provide highly precise and accurate test results.
