ProFlame® RTF-100
Sb2O3 is commonly used as synergist in halogenated FR systems. But as antimony reserves worldwide are decreasing, Sb2O3 price is rising all the way up. RTF-100 is a replacement of Sb2O3. It can completelyreplace Sb2O3 in halogen-antimony FR systems in an effective way with lower cost.fective way with lower cost.

RTF-100 used in PBT
We can find Sb2O3 can be replaced by RTF-100 completely, the FR performance is well maintained.
The most significant change is the enhanced MFI with the dosage of RTF-100, which is good for the later molding process, while other mechanical properties are basically unchanged.

RTF-100 used in PP
According to the dosage table 7 and sample test result table 8, we can find enhanced MFR(melt flow rate), enhanced notch impact strength, and significantly lower material density with the increased dosage of RTF-100.
And, when 1/3 or less the dosage of Sb2O3 is replaced by RTF-100, the FR performance is well maintained.
Moreover, PP added with RTF-100 is whiter than with Sb2O3 alone, with enhanced surface glossiness and coloring performance.
Besides, as RTF-100 is an ultra-fine inorganic powder, it can perform nucleation effect in PP compounding, reducing the molding cycle, improving material distortion temperature. At the same time it can reduce the dosage of special nucleating agent in the compounding process, thus furtherly reducing the production cost.
