Spectra Coloured Granules

Spectra granules are coloured and processed in a modernized, EU rated manufacturing and packaging plant. Our processing plant is able to colour any size granule from 0.1mm to 10mm in grain size. To date these granules include recycled cork, quartz stone, recycled rubber crumb, shred or mulch and recycled glass.

The colouring is a highly specialized process that results in each granule being individually encapsulated with a UV stable colour fast Polyurethane surface coating and then cured by a high temperature patented heat curing process. Spectra has a range of single colours and blended colour combinations. We offer a colour matching service and can match RAL and NCS colours. We produce Spectra coloured granules for multinational resin manufacturing companies and specialized markets and industries.
