Environmental Stress Cracking Resistance Chamber | Maintenance Tips

 

Environmental Stress Cracking (ESC) is the brittle failure of polymeric material from a combination of stress and environment. When a polymer is subject to both tensile stress and an aggressive environment, the resulting damage is typically much greater than when either stress is applied alone. ESC can occur in both thermosetting and thermoplastic polymers and can be tested with the help of Presto environmental stress cracking resistance tester. This is one of the amazing lab testing equipment that will be used to test the environment resistance test and material properties under certain types of stress. Here in this blog, we are going to discuss brief information about the Presto environment stress cracking resistance tester and how you can easily maintain this lab testing equipment with ease. So, we will start with the Presto environment stress cracking tester introduction. 

Introduction about environment stress cracking resistance tester 

In the plastic industry, it is important for you to determine the stress resistance of various materials like blow-molded polyethylene containers. Thus, you can easily test the resistance to environmental stress with the help of the Presto stress resistance cracking tester. 

Presto offers ESCR as it is the efficient solution for Plastic industries to check the environmental stress–cracking of ethylene plastics. Environmental Stress cracking is a property that is highly dependent upon the nature and level of the stresses applied and on the thermal history of the specimen. This lab test provides information about the long-term behavior of specimens when exposed to different stress conditions. Thus, with the use of the Presto stress cracking resistance testing instrument, you will be able to determine the effects of the environment on products using ESCR. 

Below we have listed the features and technical specifications of the Presto stress cracking resistance tester. You can also read brief information about environment stress cracking resistance tester and know more about its importance. 


Features of Presto stress cracking resistance tester

Polyethylene is a polymer that has many applications due to its low cost and easy processing. One popular application is in the manufacturing of blow-molded containers. However, these containers are susceptible to environmental stress cracking (ESCR). 

This type of failure occurs at stresses below those that would cause cracking in the absence of an aggressive environment. There are various test methods that can be used to calculate the ESCR of a plastic container. These methods are described in detail in various standards. By understanding the ESCR of a particular material, manufacturers can design containers that are less likely to fail in an aggressive environment. This lab testing instrument will be designed as per industrial standards like ASTM D 1693. Below we have listed the features of Presto ESCR.

  • This testing machine will provide you with highly accurate testing results.
  • Temperature controls through PID controller
  • Highly accurate test results under uniform temperatures in the chamber
  • Advanced Digital Microprocessor based PID based temperature controller

Test The Ductility Of The Material With Presto Cupping Strength Tester

Image
  In order to ensure the safety of structures and products, it is important to test the ductility of metals. Ductility is the ability of a material to deform under tensile stress, and it is considered to be an important property of metals. There are several methods of testing ductility but the cupping strength test is one of the common tests that will be performed on the metals to determine their ductility. This method involves measuring the amount of deformation that occurs in a metal when it is subjected to a constant tensile force. The results of this test can be used to determine the toughness of a metal. Testing the ductility of metals is important because it can help to ensure the safety of products and structures. Presto offers a high-quality cupping strength tester that will help to measure the draw ability of material, especially the metal sheets.  Here in this blog, we are going to discuss brief information about the Presto cupping strength tester and how this lab testing e

In today's marketplace, customers expect manufacturers to deliver products that meet their high standards. Unfortunately, meeting these standards can be a challenge, especially when it comes to ensuring that products are free of defects. As a result, many manufacturers go to great lengths to test their products before they are shipped to customers. By doing so, they can avoid the hassle and expense of dealing with returns and refunds. Thus, if you are a metal products manufacturer, then testing the surface coatings of your products is of an utmost important task. Therefore, you can easily test the corrosion resistance of surface coatings with the Presto  salt spray chamber .  This is one of the versatile  lab testing equipment   that will help you to assess the rust-proof ability of components with ease. It will provide you with complete testing of surface coatings against real-life weathering conditions. This  corrosion resistance test chamber  will help you to evaluate the corr
