Eustab HS-700F Highly efficient anti-hydrolysis agent for various polymers, in particular for EVA, PA, PET, PBT, PLA, TPEE &, TPU to be protected from premature wear due to hydrolysis. It also acts as a processing auxiliary to prevent a reduction in molecular weight, and may also be used to bring about a deliberate increase in molecular weight. Eustab HS-700F acts as an acid and water scavenger and prevents autocatalytic degradation. The optimum quantity of Eustab HS-700F in the production of monofilaments or industrial injection mouldings made of PET or polyamide is generally in the range of 0.5 to 1.5% depending on the desired degree of hydrolytic stability and the acid value of the original polymer. The recommended quantity for PU systems based on polyester polyols for high-grade TPU products, PU casting elastomers, PU rubber and PU adhesives is between 0.7 to 1.5%. For certain applications, e.g. in EVA, Eustab HS-700F is used between 3.0 to 5.0%.
