|LEWA metering systems process the following additives, for example:|
Extrusion is an important process in the plastics industry. Extruders must be heated, in order to melt the filled plastic granules or powder.
Some process related tasks make it necessary to cool the plasticized melt. Depending on the plastic used, other equipment is necessary, e.g., for pumping gases, which leave bubbles in the end product.
Normally other machines are required after the nozzle in the production of plastic products.
|They are subject to the following requirements:||In addition, there are the requirements for all raw materials:|
|Specific effectiveness||Good environmental compatibility|
|Lasting effect, e. g. for light stabilizers||Low health risks|
|No negative influences|
In general, the quantity used is very low and includes less than 1% of the total recipe.
