TF-201SG Small partical size Flame Retardant of ammonium polyphosphate for rubber
Introduction
TF-201SG is a kind of organic silicone treated APP phase II. It is hydrophobic. It is a modified APP with silicone.As for this modify, it features high heat stability, Strong hydrophobicity which can flow on the water surface, it also features good powder flowability, good compatibility with organic polymers and resins. In those materials like, polyolefin, Epoxy resin (EP), unsaturated polyester (UP), rigid PU foam, rubber cable, silicone rubber, the 201G has a good application in and good compatibility.
Characteristics
1. Strong hydrophobicity which can flow on the water surface.
2. Good powder flowability
3. Good compatibility with organic polymers and resins.
Advantage: Compared to APP phase II, 201SG has better dispersibility and compatibility, higher，performance on flame retardant. what’s more, less affect on mechanic property.
