Test Yellowness Index of Polymer with Precision Spectrophotometer

Test Yellowness Index of Polymer with Precision Spectrophotometer

The polymer is the most popular product having network all over the world. Yellowness Index is an important factor to be tested in plastic industries. It is a number that describes the change in color of a test sample from white to yellow. This usually happens because of over exposure to damaging environmental conditions like sunlight, dust, UV radiations, temperature etc. Various other reasons are processing functions and the purity level of raw material.

The plastic material that is used for the application is tested for its yellowness index before its use in production. This test creates important information regarding the quality of the product and its existence in the damaging conditions. Also, manufacturer can view whether their production or processing program is going well or not. For measuring the yellowness index of plastic, quality labs use spectrophotometer device.

The Portable spectrophotometer by Pacorr is designed to obtain and measure the yellowness in plastic material. The device is used widely in the polymer industry to test the purity, sustainability and degree of transparency. Using an illumination system or optical geometry of 45/0 degree and adhering to international test standards and is designed as per DIN, CIE, ASTM and ISO standard. Has an integrated sphere having 58 mm diameter, an ideal setup for spectrophotometry. The device equipped with combined LED light sources for conducting ideal test conditions. Uses highest sensing technology with silicone photodiode array type sensor. It can obtain a range of wavelength from 400 to 700 nm. An apertures size is 8mm for obtaining the yellowness precisely.

Works with large range of color spaces including - XYZ, CIE LAB, LCh, Yxy, Hunter LAB, CIE LUV. Equipped with HMI based display screen offering multiple features. Spectral Value can be accessed in graphical format. Color Difference comparison test data on a single screen (also in Graphical format). Yellowness index values or other Color measurement value can be viewed on digital screen. PASS/FAIL criteria can be set easily and based on that results can be classified. You can avail Color Simulation, and Color Offset feature.

Portable Spectrophotometer has an ergonomic design which is light in weight and is highly portable. It is very easy to place the device on the plastic material. User can take a repeatable reading of one section to ensure consistency.
