Masterbatch, manufacture

Masterbatching would also reduce the processing steps for CB manufacturers. 

To facilitate in-plant compounding, most suppliers have developed systems which efficiently and repro-ducibly deliver a controlled additive package to a compound, using either a specialised concentrate or a masterbatch formulation. Some of the polymer manufacturers have also made available advanced additive delivery systems, which they have often developed originally for their own use (e.g. Eastman, Montell). 

Plastic additives manufacturer, Clariant, is running field tests with packaging converters using polylactic acid polymers for its CESA-extend masterbatch. The aim of the new additive is to improve... 

Dispersion is also an important factor. Light reflection depends on the surface area of carbon black after dispersion. If large agglomerates are present light reflection (and UV protection and opacity) is reduced. It is a frequent practice to use fully dispersed masterbatches offered either by carbon black manufacturers or compounders to achieve good results. ... 

The converting or moulding process may also include the use of processing aids, e.g. lubricants and mould release agents. Masterbatching may contain lubricants, mould release and a carrier or base diluent which assist the manufacture of a concentrated masterbatch containing colourants. 

Masterbatching of carbon black with natural rubber in latex form has never been successfully developed industrially. There are various unrelated reasons for this failure. Natural rubber latex is more variable than are styrene-butadiene rubber latexes as regards rubber content and the plasticity of the rubber. Additionally, the geographical regions in which carbon black is manufactured are far distant from those in which natural rubber is produced. A further... 

Other dense fillers are useful for sound-deadening purposes, such as barium sulfate. Likewise, tungsten and bismuth can be used in POs to increase density and create a metal-like heaviness in consumer products. This quality is said to be potentially useful for semi-durable products like cosmetics/personal-care packaging (lipstick tubes, etc.), where the density of metal suggests quality, but where it would be cost-prohibitive to produce the product in metal. Standard plastics processing can be used with these filler compounds, according to manufacturer Clariant Masterbatches [7-19]. 

ColorMatrix Europe supply additive and colorant masterbatch for use in the manufacture of polymeric materials and articles intended for various applications such as food contact packaging, and toys. ColorMatrix Europe products may be manufactured at different manufacturing locations (USA, Europe, and Asia). The Global regulatory department based within Europe keeps an inventory of raw materials used across all global locations and manages supplier information, chemistry information and so on. ColorMatrix Europe s global inventory contains hundreds of raw materials however the majority of these are classified as non hazardous. 

According to a recent assumption, powdered SbgOa forms a health hazard. For this reason, manufacturers are attempting to market this agent in other forms, such as a dispersion, masterbatch, or granules, or by substituting it with alternative antimony compounds. 

Using resins and masterbatches in a manufacturing process (for bottles, tiles, or medical tubing)... 

Ampacet claims that it has been able to lower the range of trigger temperatures over which azodicarbonamide masterbatches work, from the usual 190-205 °C down to 170-200 °C. Bayer sells a modified azodicarboxylic acid diamide-based blowing agent called Porofor ADC/Z-C2 for foaming crosslinked polyethylene. It is claimed to allow the manufacture of lower density foams at conventional oven temperatures, with shorter production cycles than standard ADC diamides. 

Most of the world s flame retardants are sold directly to polymer manufacturers, masterbatch producers, compounders and fabricators. Not all the statistics for flame retardant sales confine themselves to plastics markets. Freedonia reports that 80% of US usage of FRs is for plastics. Smaller quantities are used in textiles, coatings, adhesives and elastomers. 

Alqemia is the new name for a group of companies involved with masterbatch production and additives. It was set up by the Israeli company Kafrit Industries following its pmchase of Constab Additive Polymers (UK) Ltd., Constab Polyolefin Additives GmbH and Areton International Plastics (UK) in late 2003. Alqemia has manufacturing operations in Israel, Germany and the UK. 

Concentrates (also known as masterbatches) of bicyclic dicaiboxylate salt (e.g., disodium bicyclo[2.2.1]heptane-2,3-dicarboxylate, commercial product known as HPN-68) are nucleating additives used to facilitate typical thermoplastic manufacturing processes. " They impart high peak crystallization temperatures. They are suitable for use in small and large appliances. ...
