New Clarifier for the Polypropylene industry makes debut at K2007

RiKA International Ltd, Manchester UK, a wholly owned subidiary of New Japan Chemical Company, Osaka , Japan will introduce a new clarifier for the polyproplene industry at K2007 ( Hall 8b Stand G47).

The clarifier RiKACLEAR PC1 imparts superior see-through clarity as well as improved impact-stiffness balance.

Historically, acetal sorbitol chemistry has been used as clarifiers by the polyproplene industry. Although giving reasonable haze values, these chemicals have a tendency to hydrolyse causing elution of aldehyde from the polypropylene and therefore, causing negative organoleptic properties and serious plate out problems. These features restrict the use of PP in certain food applications.

However, RiKACLEAR PC1 avoids these problems by utilizing entirely new chemistry to address the failings of these so called “third generation clarifiers”. Usage levels of less than 1500ppm result in haze values in 0.5mm plaques < 6% as well as improved impact-stiffness balance. As a newly developed chemical RiKACLEAR PC1 is currently completing registration and food contact approvals in Japan, Europe and the USA.

RiKA International Ltd has extensive laboratory facilities and alongside its parent company, NJC are recognised as inventors of the polypropylene clarifier technology. Once more, the company is at the cutting edge of an important breakthrough.

RiKA looks forward to talking to visitors on Stand G47 in Hall 8b during K 2007, where along with colleagues from NJC will be able to discuss to all interested parties – PP producers, processors and packaging designers - how RiKACLEAR answers the industry’s quest for the perfect clarifier.
