The MH-2800 flame retardant compound for PP tube is made in accordance with MT558.1-2005 standards. It adopts PE80, PE100 grade HDPE as matrix resin. In addition, it utilizes high-performance composite fire retardant and special conductive carbon black as functional additives.
Our eco-friendly fire retardant is firstly dispersed through our dispersant, and then it is granulated by adoption of a twin-screw extruder. It is very easy to use our product, and no pollution is caused. Our flame retardant compound for PP tube is one of the best choices of those pipes for different purposes such as coal mine gas, ventilation, drainage, spraying, or anti-static dedicated pipes.
Product Features
1. The flame retardant compound for PP tube is anti-precipitation. It can be dispersed easily.
2. Its dose varies from 12 to 15%. There is no need to add antimony trioxide.
3. Dust pollution is not found. Our product can be directly applied in injection process, thus simplifying production process and also greatly reducing costs.
4. This product is fully compliant with new EU environmental standard (RoHS). It does not contain polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).
5 The final density of retardants is approximately 1, while the other bromine-based flame retardant PE density ranges from 1.3-1.4.
6. Good mechanical properties allow the flame retardant compound to show good compatibility with resins. It is consistent with pure resins in almost all aspects of performance.
7. As a white particle, this product can be configured into a variety of colors.
