During the mixing process, the effect of the fusion of aluminum hydroxide and organic materials affects its mechanical properties. In order to determine the impact of the mixing time on the performance of the wire and cable compounds, it is concluded through experiments that when the mixing time is less than 120 seconds, the performance…
In order to meet the flame retardant requirements of the halogen-free low-smoke wire and cable standard, it is necessary to add more than 50% aluminum hydroxide. The aluminum hydroxide powder is powdery particles with a particle size d50 of less than 2um, and the polymer is generally 2-3mm. The particle size difference between the two…
Fine ATH has the three functions of flame retardancy, smoke suppression, and filling. So it is widely used in HFFR cable compounds. It has no secondary pollution during combustion, has good thermal stability, is non-toxic, has no corrosive gas, and good flame retardant effect. It has the advantages of being a flame retardant and filler…
The cable materials currently used are usually low-smoke halogen-free flame-retardant polyolefin cable materials as the mainstream. This article will analyze the formulation technology and performance of low-smoke halogen-free flame-retardant polyolefin cable materials. Formulation technology Low-smoke halogen-free flame-retardant polyolefin cable material is usually composed of polyolefin blend resin plus flame-retardant filler aluminum hydroxide, magnesium hydroxide, and…
