YS-201 Ammonium Polyphosphate
I. Product Introduction
YS-201 Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation layer.
II. Product Technical Data Sheet
III. Product Features
1. Low water solubility and low organic solvent solubility.
2. Halogen free, excellent fire resistance.
3.Suitable for cable fireproofing coatings, epoxy resin-based and unsaturated resin-based FRP composites, EVA, PE, PP, PU etc.
IV. Application
1. Used to prepare many kinds of high-efficiency intumescent coating, the flameproof treatment for wood, multistory building, ships, trains, cables, etc.
2. Used as the main flameproof additive for expanding-type flame retardant used in plastic, resin, rubber, etc.
3. Make into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc.
4. In plastics(PP, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.
5. Used for textile coatings.
V. Advantage
It has good stability in water .
The stability test of APP phase II in 30℃ water 15days：
VI. Package Storage & Transportation
1. Packed in paper and plastic bags, 25kg/bag. 24-25MT/20'FCL without pallets, 20-24MT/20'FCL with pallets.
2. Storage in cool dry place. keeping out of moisture and sunshine, min.
3. Transported as non-dangerous chemical goods. Shelf life one year.
