YIHOO FR960
Product description FR930 is a phosphorus-based environmentally friendly halogen-free flame retardant, full name diethylphosphinate. This flame retardant is a white powder, organic phosphinate. The product is moisture-proof, insoluble in water and acetone, dichloromethane, butanone, toluene and other organic solvents.
It is especially suitable for halogen-free flame retardant of high-temperature nylon engineering plastics (6T, 66&PPA, etc.), polyurethane elastomer (TPU), polyester elastomer (TPE-E) and other systems.CAS number 1184-10-7 Molecular structure

●Suitable for thermoplastic and thermosetting plastics;
●High phosphorus content, high flame retardant efficiency;
●UL94 V-0 rating can achieve 0.4 mm thickness;
●Good thermal stability, processing temperature can reach 350 ℃;
●It is applicable to both glass fiber reinforced and non glass fiber reinforced;
●Flame retardant materials have good physical and electrical properties;
●Suitable for lead-free welding;
●Good coloring performance;
●Halogen free flame retardant is beneficial to environmental protection and health.Application FR930 is a flame retardant suitable for thermoplastics and thermosets. It has high phosphorus content, good thermal stability and high flame retardant efficiency.
Due to the good high temperature stability of FR930, it can be applied to high temperature nylon, suitable for glass fiber reinforced and non-reinforced type. The flame retardant material has good physical and electrical properties.
In high-temperature nylon, FR930 is used in an amount of approximately 10% (wt) to achieve UL 94 V-0 (1.6 and 0.8 mm thickness). The amount of flame retardant used may vary depending on the polymer, processing conditions, and amount of glass fiber added.Processing technology Before adding FR930, it is necessary to pre-dry the polymer as usual. If possible, the moisture content of high-temperature nylon should be less than 0.1% by weight, PBT should be less than 0.05% by weight, and PET should be less than 0.005%. Pre-drying of ADP-33 is not required. However, if the system has low moisture content requirements, pre-drying is recommended (e.g. baking at 120°C for 4 h);
The commonly used mixing and processing method of powder can be used for FR930, and the best dosing method should be determined on a case-by-case basis. It must be ensured that all components are evenly dispersed and that the temperature of the polymer melt does not exceed 350°C.Pakcage 25kg bag
