Transparency Measurement

To guarantee consistent and uniform products, transparency measurement is a need. Depending on the application, the product has to meet different requirements in transmission, haze and clarity.

Based on the product’s application, transparent materials have to fulfill different requirements (Fig. 1). The optical properties of foils and panels for glasshouses should be highly transparent and homogeneous in light distribution, while packaging foils should display the packed product as clear as possible.
Process variations can have a major influence on the quality. The appearance of the final product is depending on the selected material and the processing conditions. Several parameters can have an impact on the optical properties.
Mass temperature – additives – mass homogeneity – temperature control – compatibility – molecular structure – cooling rate – roller surface – rheology – molecular mass distribution
Objective measurement methods are needed in research and quality control to eliminate uncertainties based on visual assessments.
