Colour and additive masterbatch manufacturer Silvergate Plastics (Wrexham, Wales / UK; www.silvergate-plastics.co.uk) has announced the launch of "SilvaFrost, a frosted-effect masterbatch that enables processors to create their own special effects. Because the masterbatch is process-dependent, the frosted effect only becomes apparent once moulding has been completed.
In the case of PET injection blow moulded containers, for example, the frosted effect cannot be seen in the preform, only once stretching is completed. This means that while the neck of the container remains clear, the rest of the moulding is frosted in appearance. SilvaFrost is available in any colour.
