Detect change in physical properties of plastics with ESCR tester

Environmental stress cracking (ESC) is a problem that has been plaguing the plastic industry for years. This type of cracking can occur in any type of plastic that would affect its quality. Environment stress cracking will occur when a plastic product is exposed to a combination of environmental factors, such as UV light, chemicals, and temperature changes. The stress from these factors can cause the plastic to crack or break. While ESC is not necessarily a safety hazard, it can be a serious issue for businesses that rely on plastic products. That’s why it’s important to test plastics for ESC before using them in any type of product. We at Presto have designed a high-quality lab testing instrument known as an environmental stress cracking resistance tester. This is one of the high-quality lab testing equipment that has been designed to detect changes in the physical characteristics of the materials.
