More than 30% of the company's employees have a bachelor's degree or above. The company collaborates with institutes like the Chinese Academy of Sciences and Sun Yat-sen University. Specializing in phosphorus-based, nitrogen-based, and intumescent flame retardants (9 product series), its solutions are applied in PP, PA, TPE substrates for appliances, automotive, electronics, and cables. Certified with ISO9001, RoHS, and REACH compliance, Complord holds multiple patents for high-performance flame retardant technologies.
Halogen-free flame retardant masterbatch HF-800M7B
HF-800M7B is a halogen-free, environmentally friendly flame retardant masterbatch using polypropylene as a carrier, which can be used in various flame retardant polypropylene products. PP flame retardant masterbatch manufacturer Zhongshan Connold recommends using masterbatch to avoid excessive dust during the production process, improve the flame retardant dispersion effect, and improve product performance.
Product introduction: HF-800M7B is a halogen-free environmentally friendly flame-retardant masterbatch using polypropylene as a carrier. It can be used in various flame-retardant polypropylene products. It fully complies with the European Union's 2011/65/EU "Directive on Restriction of the Use of Certain Hazardous Ingredients in Electronic and Electrical Equipment" (the RoHS Directive), and the requirements of environmental regulations such as REACH regulations. The flame retardant component of HF-800M7B uses phosphorus and nitrogen as flame retardant elements to form an expanded carbon layer to block oxygen and fire sources. The flame retardant grade of its flame retardant polypropylene products can reach UL94 V-0 (0.75mm), GWIT 750°C, and GWFI 960°C. HF-800M7B is not an ammonium polyphosphate flame retardant system. It has higher thermal stability and can adapt to a wider range of processing conditions. It can especially be used in glass fiber reinforced PP and can reach UL
This flame retardant also has the characteristics of low density, low smoke generation and low mold corrosion of flame retardant products. In addition, the use of masterbatch can also avoid excessive dust generation during the production process, improve the flame retardant dispersion effect, and improve product performance.
Processing precautions:
(1) The thermal decomposition temperature of HF-800M7B in nitrogen is 270°C. The processing temperature can be adjusted according to the specific situation. It is recommended that the processing temperature of the twin-screw should not be too high on the premise of ensuring uniform dispersion and blending of the flame retardant to avoid a small amount of flame retardant decomposition and slight foaming. At the same time, a certain degree of vacuum must be maintained during the twin-screw extrusion process.
(2) Screens can be added during the extrusion process of non-fiber-added systems, but the mesh number of the screens should not be too high.
(3) Substances in the system that have adverse effects on flame retardancy: Some inorganic fillers will affect the flame retardant effect, and calcium carbonate will seriously affect the flame retardant effect. When adding talc, barium sulfate, and wollastonite, the amount of flame retardant needs to be increased appropriately; when the amount of carbon black added exceeds 0.5% (or the amount of black masterbatch added exceeds 1%), the flame retardant effect will decrease; additives or toners containing Br and Cl (such as phthalocyanine green) may cause the flame retardant to fail.
