Like people, and the entire population of living creatures, polymers undergo aging too. Even though they’re not a living thing but they also have a particular life expectancy. When polymer ages, they too become fragile and can easily get damaged. And this can be a matter of life and death depending upon the application of that polymer. Hence, evaluating the quality of polymeric substances by simulating aging environment can be important for long-term plastic applications. This kind of test can be conducted by using a highly efficient Accelerated aging oven.

A factor which causes polymer aging?

Usually, a combination of environmental factors, such as temperature, and UV light exposure, visible light, humidity, or reactive liquids can affect the quality of polymeric products. The aging processes can be further categorized into physical aging, chemical aging, thermal aging, etc. Most of the polymers are amorphous in nature and undergo physical relaxation and other structural modification with the passing time. It is said, that softer a polymer is, the more flexible its polymer chains will be, and the more prone it will be to aging effects. The polymer’s chemical composition, the concentration of oxidation-prone chemical groups, and the number of additives can also hold a strong effect on the aging process. Hence, evaluating polymer aging is important to avoid future accidents. 

Labtiger presents a highly efficient accelerated aging oven which is utilized in medical industries to evaluate the shelf life of the products by assessing the effects of aging on them.

This aging oven is in compliance with the ISO-188 testing standard. It helps manufacturers and lab technician of medical industries in evaluating the nature of various products which will be stored for a particular time period. Using this testing chamber, one can analyze the properties of a polymer under environmental factors for a particular time period which simulates the effects of the long-term aging.

In an aging oven, the test is conducted by keeping the sample under high-temperature condition for a particular time period. The rising temperature produces the aging effects in a shorter time which are similar to the normal aging conditions faced by the product for a longer time. After the test is conducted, the hardness modifications of the products can be evaluated. The modifications in hardness of the products indicate the percentage changes in the properties of the polymer product leading to its quality analysis for a long time period.
