INV 7000-1 Efficient Polyester Hydrolysis Resistant Solution

Physical properties

Product Features
INV 7000-1 can react the active terminal carboxyl groups produced after the hydrolysis of the polyester molecular chain, prevent the further progress of the hydrolysis reaction, thus effectively inhibiting the degradation of the mechanical properties of the material caused by hydrolysis , greatly prolonging the service life of the product.

Technical advantages
· Using the latest synthetic technology, the stability is better;
· High activity, fast reaction with carboxyl group;
· High purity, no isocyanate residue;
· It is superior to similar foreign products and widely used.

Typical Application
· INV 7000-1 can be widely used in PU products, such as TPU, castable PU elastomer, PU adhesive, PU coating, PU For shoe sole stock solution, PU microporous elastomer, etc., the general addition amount is 0.5-2.0 phr, which can significantly improve the hydrolysis resistance of the product.
· INV 7000-1 is generally applied to polyurethane systems in a molten state, and the processing temperature is not lower than 50°C.
· Polyester polyols: the addition amount is 0.5-1.0 phr, which can quickly reduce the acid value of polyols and improve the hydrolysis resistance of materials.
           

TPU: Add different parts of INV 7000-1 to TPU, after a certain aging time, the stretching of the material will be improved.The retention rate of temperature and elongation at break are much better than that without adding INV 7000-1 (70°C boiling test).
           

Storage Stability
It can be stored for at least one year in the original packaging under airtight and dry conditions.

Packaging Specifications
10kg cold-rolled iron drum or 25kg lined PE paper drum.
