Tosaf Product Aids Extrusion Coating

Published: May 03, 2017

AFULA, ISRAEL | Tosaf Compounds announces ME800047, a newly developed white masterbatch for extrusion coating applications. Reportedly, its increased heat stability reduces smoke and odor when processed at high temperatures, and it contributes to a higher production efficiency compared to traditional products of this kind.

According to company, known challenges of extrusion coating include necking (the melt dripping unevenly on the sheet in a neck shape), heavy smoke, and strong odor due to the high processing temperatures, poor dispersion, gel formation, and die buildup.

To overcome these issues, ME800047 is said to withstand the extremely high processing temperatures while at the same time maintaining its high dispersion quality. This results in a constantly homogenous coating and reduces the need for filter changes during production. Gel formation is said to be significantly reduced, and its opacity allows for a lower addition level of ME800047, even in very thin layers. And because this new white masterbatch does not contain migrating additives, it provides high corona retention, good printability, and reduced die buildup, company adds.
