Emulsion – polymer production in an emulsion 'phase' has a number of process advantages, including prevention of coagulation of product. Products produced by such polymerisations may be used as the emulsions – products including primary components for glues and paints. Synthetic latexes (rubbers) are also produced by this process. Emulsion An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms "colloid" and "emulsion" are sometimes used interchangeably, "emulsion" should be used when both phases, dispersed and
Glass milk bottle mainly measured in Imperial pints (but labelled 568ml), because the glass bottles are 'returnable', which means they were excluded from metrication. However, sterilized milk sold to the door is in 500ml glass bottles (and is 'non-returnable' and has colour coded lids that match the colour codes normally seen on plastic bottles). Often, in supermarkets they are sold in pints but labelled with their metric equivalent (568ml). Quantities larger than a pint are generally sold in metric units or multiples of a pint. With lower milk consumption, milk in Hong Kong is sold in both glass and plastic bottles as well
