Carbonic Acid Esters (CAE): a sustainable chemistryBack
Thanks to our proprietary know-how and efficient production with one dedicated reactor, we internally developed this unique chemistry available for multiple applications: Carbonic Acid Esters are synthesized by renewable raw materials and biodegradable.
1 CAE vs other chemical groups
Mineral oil is cheap and easily available, but it features poor biodegradability (less than 30% ) and toxicologically unsafe byproducts, when not specially refined.
Ester oil is more expensive than mineral oil, provides superior abrasion protection, and features average biodegradability (typically ca. 80% ), but presents heater deposits.
Special EO/PO provides better water solubility and improved migration stability, but also lower lubrification and poor biodegradability
Carbonic Acid Ester oil is completely soluble, easy to wash and readily biodegradable; features excellent thermostability and the highest lubrication performance.
2 CAE environmental footprint
CAE is synthesized by renewable raw materials from no animal derivatives and no SVHC; it can be applied through an environmental-friendly process at low temperatures, without any solvent and polluting byproducts.
CAE is readily biodegradable (according to OECD 301) and doesn’t require emulsifiers, improving wastewater systems.
3 CAE as sustainable spin finishes and coning oils
CAE has been elected the sustainable choice as spin finish and coning oils for its unrivaled performance of wettability, ease of washing, and cost-effectiveness.
Excellent ease of washing:
- saving washing costs by shortening the washing time or eliminating the pre-wash
- reduction of non-conformity caused by finishing faults (no mineral oil spots, streaks, or stripes)
- there is no need for machinery for exhaust fumes cleaning and reduction of the running costs on previously installed equipment.
Wettability: lower surface tension & improved thread line stability during texturisation.
Compared with generic spin finish or coning oils, CAE features better lubrification, lower friction, and more uniform yarns (fewer tide spots, loops), thanks to its inherent properties.
Cost-saving: optimal performance in POY application field & good performance at lower OPU content.
At a lower opu level (0,32%), we obtain the same friction performance as for generic product OPU level of 0,55%.
Even at a lower OPU level, the abrasion test is significantly better.
Thermostability: can be modulated up to 300°C
