Physical and chemical properties:
This product is especially suitable for use in solvent PU adhesive layer, in addition to the products made with self-extinguishing, but also can improve light resistance, water resistance, anti-static and improve product gloss and other properties, and only a low amount, it You can achieve good flame-retardant effect. After finishing textile fiber strength, feel not affected. Product low toxicity, no pollution.
Usage:
1.Mainly used as a solvent nitrocellulose, shellac, cellulose acetate and the like. Also used to produce unsaturated polyester resins, plasticizers, synthetic detergents, but also for flavors and fragrances and cosmetics and other products sensitive to odors.
2.Mainly applied to chemical fiber, cotton, polyester, nylon and other fabric flame retardant finishing and coating, the indicators of the product color, acidity, moisture and odor are met or exceeded the level of imports of similar products, can replace imported products, reducing manufacturing cost.
