Surface treatment of aluminum hydroxide can significantly improve the filling of fine aluminum hydroxidePerformance in PVC compounds. The flame retardancy of PVC cable compounds, mechanical properties, and electrical insulation is better. Surface modification is conducive to the flame retardant effect of aluminum hydroxide filler so that the fine aluminum hydroxide inorganic flame retardant filler has…
LSFR Cable refers to the sheathing material in the cable and insulation in wires. The HFFR/LSFR is made of a thermoplastic compound that emits limited smoke, no halogen as compared to normal cables. Besides, it will not produce any poisonous gases when exposed to fire. In the event of a fire in a building, there…
Fine Aluminum Hydroxide (Fine ATH) is an inorganic white fine crystal, non-hygroscopic powder. Its solubility in water and organic solvents is very low. By volume, ATH is the largest non-halogen flame retardant (NHFR) used in various end applications including cable compounds. The working principle is based on the thermal decomposition of aluminum hydroxide into aluminum…
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…
Fine ATH(Aluminum Trihydrate) is a good flame retardant used in PVC compounds. Polyvinyl chloride (PVC) is a low-cost polymer material, and it is easy to process. However, when it burns, it produces a lot of smoke, decomposes toxic and corrosive gases, suffocating, and is the main cause of death in fires. The application of fine…
Aluminum Hydroxide, also known as Aluminum Trihydrate (ATH) is an inorganic white fine crystal, non-hygroscopic powder. Its solubility in water and organic solvents is very low. By volume, ATH is the largest flame retardant (FR) used in various end applications. The working principle is based on the thermal decomposition of aluminum hydroxide into aluminum oxide…
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…
Inorganic flame retardant Halogen-free flame retardant The difference between halogen-containing flame retardants and halogen-free flame retardants: The inorganic flame retardant does not contain carbon and its carbon compounds. The inorganic flame retardant may contain halogen elements. Halogen-free flame retardants are flame retardants that include both halogen-free and inorganic standards. Halogen-containing flame retardants and halogen-free flame…
Phosphorus-containing flame retardants cover a wide range of inorganic and organic compounds and include both reactive products which are chemically bound into the polymer material as well as additive products which are integrated into the material by physical mixing only. They have a broad range of applications and good fire safety performance. The most important…
Alumina Trihydrate and Magnesium Hydroxide are the most commonly used inorganic flame retardant. Alumina trihydrate (ATH, also read Aluminum Hydroxide) is by far the most widely used flame retardant. It is of low cost, but usually requires a maximum loading of more than 65% in the polymer. Its flame retardancy effect is based on the…
