Spanish researchers plan to develop masterbatches containing almond shells
AIJU – Spain’s toy research institute – is co-ordinating a project that aims to develop masterbatches using agricultural waste products, such as almond shells, together with biodegradable polymer carriers. Target applications include toys
MASTERBATCH
Americhem launches black nigrosine masterbatches
Colour and additive systems supplier Americhem has a new line of highly concen- trated low-aniline nigrosine black masterbatches, which are available in PA 6 and 6,6 carriers at concentrations up to 40%. Compared to carbon black, the new products are said to provide a deeper black, higher gloss and minimal stress whitening. Due to their minimal impact on physical properties and suitability for use with glass reinforced polyamides, Americhem says the new masterbatches are likely to find applications in sectors such as under-the-hood automotive parts. They can also be combined with carbon black where high UV stability is required. Americhem has also
PVC PLASTICIZERS Galata extends Drapex plasticizer range
Galata Chemicals has added Drapex Alpha 200C to its family of natural oil-based primary plasticisers.
www.compoundingworld.com Intended for use in white
and clear PVC formulations or applications requiring high levels of performance, the
200˚C grade is said to provide improved extraction resist- ance, reduced VOCs and better processing. The company says
the plasticizer is pitched at applications requiring the performance of trimellitates. ❙

PIGMENTS
Cappelle targets technical polymers
Belgium-based Cappelle Pigments has introduced a new bismuth vanadate pigment – Lysopac Yellow 6619B – intended for use in technical polymer com- pounds up to 300°C. The 6619B pigment offers
Target applications include under-the-hood components
introduced ePVC – a precol- oured capstock compound for the decking and exterior profile market. According to the company,
the ePVC capstock compound provides improved strength and weathering resistance along with better colour retention, scratch and mar resistance and impact
performance. The com- pounds also reduce moisture penetration into exterior profiles, reducing risk of rot. The ePVC compounds
have undergone extensive weather testing. They can also be used with Amer- ichem’s nGrain simulated woodgrain effect. ❙

a green-yellow shade providing high light fastness as well as the thermal stability required for polymers such as PA and PC. It is said to be easy to disperse in the polymer. Also new is Lysopac
Yellow 6618B. Providing thermal resistance to 230°C, the grade provides improved reflow in powder coating applications. ❙
