| | Pigments in Plastics | £250.00 | | Rapra Polymer Bulletin |  | | This Polymer Bulletin is a current awareness service from the Polymer Library, the world's largest database dedicated to polymer literature. Each time the abstracts database is updated with new records (approx. every two weeks) you will be sent a bulletin alerting you to any items that relate to plastics pigments. Please see the sample issue below (request further samples)
Pigments are coloured, finely divided solids essentially used in the colouration of materials. They are used in the colouration of plastics because they are soluble in their polymeric application medium and because they have superior fastness properties and migration resistance. A pigment is incorporated into a plastic by a dispersion process. Whilst the plastic is in its molten state, the pigment is added and after the plastic solidifies the dispersed pigment particles are retained physically within the solid polymer matrix thus providing colour.
The main reasons that pigments are incorporated into plastics include aesthetic reasons and market appeal. However they are also used to determine whether the plastic medium will be opaque or transparent or for functional demands e.g. mechanical reinforcement of the plastic or for the inhibition of polymer degradation. As well as having beneficial effects, the inclusion of pigments into plastics may occasionally produce problems such as the warping of polyolefins as a result of uncontrolled nucleation.The ability to produce the desired optical effect in the plastic product is obviously a prime requirement in the plastics industry. However the pigments must also be capable of withstanding the effects of the environment in which they are placed, both in processing and in their anticipated useful lifetime. Pigments are selected for a particular application on the basis of their technical performance but also with due regard to toxological considerations and cost.
A Current Awareness service from Rapra may be just what you need to update your knowledge with ease and accuracy without having to waste time, effort and money finding the information yourself.

NEW PIGMENT CARRIER.
Denkinger P; Wenning A (Degussa AG)
The chemistry and properties of a new pigment carrier, a special ketone condensation resin (Synthetic Resin TC), are briefly described and compared with those of an industrial standard, urea-aldehyde resin. The performance of both these resins in pigment preparations and in alkyd and polyurethane-acrylate coatings are also compared and the mechanical properties, colour properties, stability, tinting strength and weather resistance of the coatings discussed.

CORROSION PROTECTION AND THERMAL FUNCTIONS OF CARBON-FILLED SILICONE COATINGS FOR STEEL SUBSTRATES.
Maruthan K; Selvaraj M; Jayakrishnan P (India,Central Electrochemical Research Institute)
Thermal protective coatings were prepared from a silicone polymer and various conductive pigments (lamp black, activated charcoal black, acetylene black and graphite) and applied to sandblasted mild steel panels. The abrasion resistance, impact resistance, chemical resistance, salt spray resistance, high temperature resistance and electrochemical properties of the coatings were investigated and surface morphology of the coatings characterised by scanning electron microscopy to determine the size, shape and surface changes occurring in the coatings arising from the use of different pigments. 14 refs.

PREMIUM BLACK PIGMENTS YIELD SAVINGS IN PRODUCTION OF BLACK POLYESTER FIBERS.
Grotti G (Cabot Corp.)
A fibre model developed by Cabot to simulate the total cost of producing black polyester fibres is described and used to calculate the costs relative to four steps for the production of a regular fibre pigment and a premium black pigment (Black Pearls 4560i and Black Pearls 5560). The steps are polymerisation/compounding, central polymer filtration system, screen pack and labour costs and spinning costs/fibre value. The cost benefits achieved using the premium black pigments are demonstrated.

CAMPUS DATASHEET FOR POWDER T BLUE 7174 MAC, A POLYAMIDE-11 FROM ARKEMA.
ARKEMA
CAMPUS datasheet for a blue powder polyamide-11 pigmented by dry blend. Designed for the coating of tubes, pipe systems, flanges and fittings for the transport of fluids in particular potable water. Coating done by dipping of pre heated part in a bed of fluidised powder. The product is submitted to potable water approval. This datasheet is one in a range of datasheets provided by Materials Data Center from the CAMPUS (Computer Aided Material Preselection By Uniform Standards) database. All data is measured according to strict CAMPUS ISO standards, thus ensuring a high standard of data comparability across different manufacturer's datasets. For an indication of properties given on the datasheet, please see the list of keywords below. If appropriate, this datasheet PDF is updated at 3 monthly intervals. For subscription information regarding the Materials Data Center, please follow the link on the Rapra Polymer Library home page http://www.polymerlibrary.com

BEER IN PET: RECYCLING CONSIDERATIONS.
As a global leader in bottle-to-bottle production, Amcor PET Packaging takes a keen interest in the impact of coated and multilayer beer bottles on the bottle-to-bottle recycling chain. At the company's recycling plant in Beaune, France, state-of-the-art technology produces food grade resin ready to be reused in drinks bottles. The recycling facility is able to handle coloured bottles, multilayer bottles, coloured multilayer bottles and even coloured coated bottles. There is no need for pre-sorting. Beaune can produce 24,000 tonnes of resin pellets from over 30,000 tonnes of post-consumer PETP, equivalent to approximately 700 million PETP bottles. Around 17,000 tonnes of the resin produced is of food grade quality, known as Amcor SuperCycle, while the remaining 7,000 tonnes of NuCycle is used for non-food applications. Amcor recommends a 25% content of SuperCycle resin in new multilayer beer bottles.

HEYWOOD WILLIAMS SELLS PLASTIC PROFILES UNIT.
Higgs R
It is briefly reported that Heywood Williams is selling HW Plastics, its UK plastics systems division, to Latium Plastics Holdings, a private British PVC profile extruder, window fabricator and installer. In 2003, Heywood Williams successfully sued Tioxide Europe for compensation over the discolouration of PVC profiles that Heywood Williams sold in the 1990s. Latium Plastics Holdings owns two leading British window fabrication businesses, Everest and Weatherseal, as well as other glass interests. HW Plastics recorded sales last year of almost 66m pounds sterling, representing about 20% of the parent company's sales, with an operating loss of 4m pounds sterling.

BRIGHTNESS OUT OF INTENSITY? COLOUR EFFECTS BASED ON LIQUID CRYSTAL POLYMERS.
Heinlein J; Kasch M (Wacker Chemie GmbH)
German
Consumer markets show an unbroken trend towards individualising products. Pigments with liquid crystal effects offer new possibilities in colour design. They can be used in paints as well as plastics. Aspects covered include helical structures and stable colour flop through acrylic groups. It is shown how shearing forces optimise liquid crystal order. The pigment effects from liquid crystals are reviewed for their use in water-based paint systems, in powder paints and screen printing inks. Other topics include the use of such pigment effects as a colour-intensifying additive on car bodywork.
