RAPID MEASUREMENT OF PIGMENT SEPARATION OF A PASTE COLOUR FOR LSR CAN HELP SPEED UP THE UP THE PRODUCT DEVELOPMENT PROCESS AND INCREASE SPEED TO MARKET

摘要

Colourant dispersions offer numerous processing and quality benefits for Liquid Silicone Rubber injection moulding applications. The right formulation can result in more effective homogenisation with the LSR for efficient processing and consistent colour dispersion, boosting production efficiency and aesthetic quality. Over time, dispersions are susceptible to separation or sedimentation which directly influences product stability and shelf life. By increasing the speed at which the rate of separation for a specific formulation can be measured and predicting the rate of separation, colorant additive suppliers can offer customers optimised inventory management, rapid product development and increased speed to market. This paper covers the fundamental basics of colour paste dispersions for LSR and the technological advancements in stability analysis equipment and software that enable rapid measurement compared with more time-consuming, traditional means.
