Compare 11 controlled grades across the SPHERON A and E series. Every product has a dedicated technical page and datasheet.
Review the key parameters of every particle-size grade in one place. Select a starting point by particle size, density, colour and process requirements.
SPHERON A has a white-to-light-grey colour profile and is intended for projects where material appearance and lower true density are important selection criteria. The actual visual and performance result should be verified using a representative application sample.
SPHERON E has a light-grey-to-grey colour profile and parameters developed for industrial applications. Selection should compare not only colour but also density, sinker content and material behaviour during incorporation and mixing.
