Climate Aging Test

The so-called”climate aging” test is a research technique that exposes polymer samples to conditions of the atmosphere to discover the elder law of the materials exposed to the air environment, study the characteristics of polymer materials, and estimate their life span.


Two kinds of tests foraging in the climate


  • Another is the test of natural exposure. The test sample of the polymer will be exposed to atmospheric conditions to observe the changes in the material in its natural surroundings. The information on aging gathered by this testing method of foraging is the most precise. The most efficient method to determine aging behavior in molecular materials; however, the test cycles are too lengthy, long-lasting, and time-consuming.


  • The other test is the artificial climate age test. Artificial climate testing refers to the method for aging that simulates real-world atmospheric conditions inside or increases the strength of a specific environmental element to create the characteristics of aging of substances quickly. It’s also known as artificial simulated aging or an acceleration of the process of aging. Artificial climate aging is typically performed inside an artificial climate chamber for aging. The most frequently used synthetic climate chambers include xenon lamps for the climate age chamber and the test chamber for fluorescent lamps that tests climate in the carbon-arc lamp climate age test chamber. These test chambers for climate aging mimic or enhance natural environmental variables from significant climatic variables like temperatures, light, and rain to create aging of the material. Furthermore, the aging test material should be conducted by specific test specifications.


Hot Air Aging Test

It is one of the significant factors contributing to polymer materials’ aging. The heat can speed up the movement of polymer chains. It can cause the polymer chains to break, create active free radicals and trigger free radical chain reactions that cause degradation of polymer or exchange.

The test for the aging of hot air is among the most popular tests for evaluating polymer materials and analyzing the resistance to aging in polymer materials. It is typically conducted in an oven heated continuously in a test chamber.

The specifications of the test may determine the temperature of the drying oven. The polymer material is regularly examined and sampled when exposed to the elements of dryness to understand the aging characteristics and properties of the polymer material to alter the polymer material specifically and increase its performance.


Temperature Alternating Aging Test

The temperature is another aspect that contributes to the aging process of polymer material. For adhesives made of polymer, high temperatures can increase the speed of motion of the chain of polymer adhesive, and low temperatures may cause internal stress to the adhesive polymer. Alternation causes chain rupture for polymer adhesives and degrading and the process of aging.

For rubber, extreme temperatures could accelerate the movement in molecular chains and Cross link with the material. A low temperature could cause damage to an increase in the size of the chain to break, which makes it more brittle and decreases its elasticity and aging.

The high – and low-temperature alternating testing of aging is a test to determine the resistance to the temperature of polymer materials. It is typically conducted in a temperature alternating test chamber, starting at an exact temperature of T 1 (generally the room temperatures) to a specified temperature, at an unvarying heating rate T 2, and maintaining temperatures of the T 2 over a specified period, then lower the temperature until a specified temperature T 3 using the same rate of cooling and maintain that temperature over a specified time, then increase the temperature to T 1 and an alternating temperature. The length of the cycle can be determined based on the specific requirements of the test.


Damp Heat Aging Test

The test for damp-heat is a reliable method of evaluating the resistance to aging of polymer materials in a high-humidity and high temperature. In an environment with high humidity, water may penetrate the polymer material, which causes the material to expand. Certain groups of hydrophilic compounds are hydrolyzed, leading to the polymer’s aging and degrading.

Additionally, the penetration of water into the polymer material may also lead to the dissolution and transfer of additives in the polymer material, including compounds, and various other substances, which can influence the material’s mechanical properties.

Through the use of heat that is high, it can encourage water infiltration. The heat increases the motion of polymer chains, decreases the intermolecular force, encourages the infiltration of water, and speeds up the degrading process of polymer materials.

Different polymer materials have distinct formulas, and their damp-heat-aging mechanisms are distinct. Different aging standards must be chosen based on the different polymer materials before the test for damp-heat aging.

A damp test for aging is typically performed in the damp heat aging test chamber, and the humidity and temperature can be adjusted according to the requirements of the test.


Medium Aging Test

Certain polymer substances must be immersed in a particular medium for a prolonged duration. For instance, the polymer material found on the equipment involved in marine or submerged operations for extended periods should be immersed in seawater for a prolonged duration. At the same time, specific components of aircraft used for aviation must be exposed to air for a prolonged period. This demands that high molecular polymers have a robust dielectric resistance to aging.

The test of aging in media is a standard test technique for evaluating the resistance to aging of media polymer materials and predicting their lifespan in a specific medium. The media used for the aging test can be made depending on the setting where the polymer is utilized. It could be saltwater, artificial seawater rainwater, acid-base solutions, gasoline oil, and various organic solvents.
