Polymer Chip Drying - Spot Check Measurements (.pdf)
Drying of polymer chips, prior to molding and extrusion processes is required to reduce free moisture content. The use of moisture laden chips has an adverse effect on product quality in terms of strength and achieving a consistent, flawless appearance. Also, with PET, the most common material used

Polymer Coatings
, or chemicals. Environmental factors also drive the technology behind polymer coatings replacing chrome and cadmium coatings. This is partly due to increasing concern about heavy metals. Also, automakers must now contend with acid rain in addition to salt spray, and polymers surpass chrome and cadmium

Polymer - Iodine Value of Oils with Model 412
An important characteristic of a fatty oil product is its iodine value (IV). This is a measure of the unsaturated fatty acid content and indicates the ease of oxidation or the drying capacity of the product. Empirically, the IV is expressed in terms of the number of centigrams of iodine per gram

Coating of Brake Disc
temperatures reach around 340°C. The number of stations here also depends on the discs’ weight and shape, as well as the coil shape, and each station has a SINAC PM 100 converter (100 kW). Curing refers to the toughening or hardening of polymer material by cross-linking polymer chains. It can be achieved
