Clariant improves its masterbatch products

Recently, special chemical manufacturer Clariant's Cesa®-extend , a modified masterbatch product, is mainly used to repair polycondensates such as PET, PLA and polycarbonate recovered from high-end packaging to restore its main materials. Performance, to achieve recycling.

Cesa®-extend masterbatch presents a more economical and practical option for the trader, one can increase the molecular weight of the polycondensate at a lower cost, and restore its physical properties due to molecular chain breakage during processing and recycling. , such as melt strength and processability. By adding the product during the recycling process, the broken molecular chain can be reconstructed to increase the chain length. Given that long-chain molecules can provide excellent tensile strength for extruded materials, the resulting packaging materials are superior in performance, so both PET and PLA extrusion processes require certain molecular chain lengths.

Peter Prusak, head of marketing for Clariant North America, said: “The market today has an ever-increasing demand for recyclables in food packaging. In this environment, Cesa®-extend, which is inexpensive and sustainable, is consistent with sustainable development. Masterbatch is undoubtedly the ideal choice for manufacturers, these masterbatch particles are suitable for various product formulations and production processes, and can effectively control and enhance including melt index, intrinsic viscosity, hydrolysis stability, mechanical properties and transparency.
