Silvergate manufactures colour and additive masterbatch. Colour masterbatch is the product that determines the colour in plastic mouldings, extrusions, sheets or films and additive masterbatch delivers other benefits to those products. Examples are resistance to fungal attack and resistance to degradation through ultra violet light. Both types of masterbatch are created prior to the mix of ingredients that create the plastic product. Masterbatch is therefore a premix and is delivered to customers in the form of pellets.
