The NEXAMITE® product range includes efficient IV enhancers/chain extenders for PET and rPET. Our solutions improve the properties and processing of both virgin polyester and recycled polyester. Ready-to-use and without the need of any additional investments these masterbatches enable, with only a small addition level an efficient and fast way to increase the melt strength and intrinsic viscosity (IV) without the need of any solid-state polymerization in various PET applications.
Our latest development NEXAMITE® F102 is specifically tailored for rPET fiber spinning. It enables the use of lower quality rPET sources, not limited to bottle grade rPET.
| Properties: | Effect: | Benefits: |
|---|---|---|
| Improve hydrolytic stability Increase IV and melt viscosity Process stabilization | Reduced cost: | – Enables use of higher amounts of r-PET and lower quality r-PET – Eliminate or reduce the need of Solid-state polymerization – More robust production process and higher productivity – Ease of handling and dosing to improve working environment in the plant |
| Increased productivity: | – A high melt strength enables the foaming process and production of high-performance foam products – Stabilise process during film extrusion to avoid interruptions and loss of capacity – Improved bubble stability in blow molding More consistent melt viscosity | |
| Improved product performance: | Increased mechanical performance and product strength |
