When rubber arrives at our factory it needs to be milled and granulated in order to make it processable into finished product. Chemipat has an enviable range of milling and granulating equipment, as well as Barwells used to remove contaminants such as particles of unmilled or cured rubber, depending on the products being processed.

	Rubber Mills, of which Chemipat has three, are used to mill the rubber to a required plasticity. They are also routinely used to mill-in fillers and additives which need to be included at this stage, such as Zinc Oxide into natural rubber to make the compound for medical dressing adhesives.
	Granulators are used to "chip" the rubber into small, regular-shaped pieces to facilitate easy dissolving and to dust the compound with such as French Chalk or Zinc Stereate to prevent "blocking".
	A Barwell is used to remove any lumps assuring a clean, homogenous finished compound, ready to go to the Wet-Mix shop or to be despatched to the customer for further processing.
