CADMIUM PIGMENTS
We manufacture a complete range of cadmium pigments from a greenish yellow
through orange and red to deep maroon. As well as offering a range of standard
pigments on its shade card,
JMB offers a service to match pigments with those customers may already be using. You can download a matching request form here (Word format) or here (PDF format).

JMB cadmium pigments are manufactured using very high purity raw materials and
all batches undergo special treatment during processing which enables them to
comply with special requirements – for instance, those of the Council of Europe for pigments in food-contact
plastics.
These products also comply with the requirements of the US "TCLP" and are not,
therefore, classed as being hazardous for disposal in the USA. For more

The European Commission has completed the first comprehensive risk assessment of
cadmium pigments and has concluded that they produce no significant risk either
to man or to the environment. For more information, click here
The manufacture and supply of cadmium pigments by JMB is covered by a formal
quality system conforming to ISO 9001 (2008) with BSI QA. For further

APPLICATIONS
Plastics (general)
Cadmium pigments have inherent high temperature resistance because of their
method of manufacture and may therefore be used routinely in polymers which are
processed at or above 300ºC e.g. polycarbonate, nylons and PTFE. Further, because of this high temperature
resistance, all moulding sprues and off-cuts can be recycled whereas an organic
may already be starting to undergo decomposition during moulding and be unable
to withstand further heating.
Toys
The use of colourants in toys is controlled in the EU by European standard EN 71 part 3. JMB has carried out tests on a wide variety of plastics moulded with up to 1% of its full-strength cadmium pigments. In all cases, the amount of cadmium extractable from the moulded article was at least a factor of ten below the maximum limit set in EN 71 part 3. For more information, click here
Artists' colours
Cadmium pigments have long been the standard against which other pigments are judged by artists and they continue to be the only choice for top-quality oil and water colours. For more information, click here
Ceramics
The colouration of decorative ceramic products such as
on-glaze colours, porcelain enamels for steel and glass colours for both flat
glass, tumblers and bottles often depends on the use of cadmium pigments. They
are the only pigments available for bright yellows, oranges and reds (which
continue to be such popular colours) which are capable of withstanding the
firing processes during manufacture and application.
