How does plastic fillers, binders, plasticizers and other additives help the formation of plastics. Are there any certain ratio of measurements required in forming a plastic?
Fillers - Generally an inert substance added to the plastic to make it cheaper. The addition of filler generally reduces the properties of the final article.The amount is dependant on the properties on the end product and cost required. Binders - Generally a resin to hold a substance together, ie the plastic in paint (the resin) is added to the other ingredients to hold them together (ie pigments colouring etc) (this is amongst other reasons. Plasticisers - Added to either help in forming a continuous film, such as in paint (normally called a coalescent) or to help the plastic become more flexible. There are many measurements required. It will largely depend on the application. Some are flexibility, hardness, colour, impact resistance, UV resistance, abrasive resistance, clarity, strength, elasticity, strength, etc Another area were measurements are required are in the manufacturing area. Some of these are viscosity, temperature, gloss, dry time, water content etc. Other additives briefly Pigment for colour Solvent for application purposes Waxes to allow processing Etc This is a very large question if you need anything more specific let me know
problematic stuff. search onto yahoo or google. just that could help!
