Dental material color stability tester

Product description

　　The Dentistry Base Polymer Search Stability tester is an instrument used to evaluate the 

color stability of dental base polymers under different environmental conditions. A base polymer 

is a material used for dental restoration and correction, such as dentures, braces, dentures, etc. 

Due to long-term use and the influence of the external environment, these base polymers may 

undergo color changes, affecting their beauty and durability. The color stability tester evaluates 

the color change of the base polymer under these conditions by simulating different environmental 

conditions, such as light, temperature, humidity, etc. Testers usually use standardized test methods 

and parameters to ensure the accuracy and comparability of test results.

　　During the test, a sample of the base polymer is placed in a tester and exposed to 

predetermined environmental conditions. The tester records the initial color of the sample 

and re-measures the color of the sample after a certain interval. The color stability of the base 

polymer can be assessed by comparing the initial color with the color of subsequent measurements. 

The use of this tester can help dentists and technicians to select polymer materials with better 

color stability, thereby improving the effectiveness and durability of repairs and corrections. At the 

same time, manufacturers can use this tester to evaluate and improve the color stability performance 

of their products.
