Standard polyamide flame retardant
Melamine is the standard polyamide flame retardant for the non-enhanced polyamide application, and the dosage is the same as the organic phosphonate. But in glass fiber enhanced performance can only achieve V2 in polyamide, and cannot be used for PA66, because the temperature over 275 ° C (higher than the PA6 PA66 melting range about 45 ° C) will start to degrade. But its electrical properties are good and the parts can be made into any color. Therefore, if the application is not high for flame retardation, this is a cost-effective solution.
The red phosphorus in polyamide flame retardants is only 7% and can reach the V0 level in the fiberglass reinforced polyamide 66. This is a flammable powder, so it is often used first as a flame retardant. The mechanical and electrical properties of finished products are good, but it should be noted that hydrogen phosphate is released during processing, and copper wire corrosion can occur in the humid and humid environment. In addition, the color of the finished product is limited to dark red, brown and black/gray due to the limitations of red phosphorus itself.
The research report shows that the polystyrene brominated polystyrene, which is synergistic with antimony trioxide, is a very outstanding solution: the components are of good mechanical properties and the hot wire is high and can be colored. But the electrical performance is not the best, and the application of the requirements for unit weight of the unit, the density of the additive system is not an advantage. Generally 30% glass fiber reinforced polyamide 66 density at 1.35 g/cm3, such as containing Br/AtO flame retardant is not close to 1.70 g/cm3. Consumer electronic products are more demanding than industrial electronic devices, and halogen flame retardants are a significant disadvantage.
The organic phosphonic acid salt additive is low in nitrogen, and the components have high performance and mechanical properties and can be colored. The density of a 30% glass reinforced PA66 with the flame retardant system is usually around 1.46 g/cm3. Compared to the complex of polystyrene and antimony trioxide, the total weight of the materials needed to make the injection-molded parts using phosphonates was 14% less.
In the past few years, the thermal stability of polyamide compounds has been limited by nitrogen synergistic agents. So a lot of work has been done to develop systems that use different synergies. Suitable phosphorous flame retardant synergistic agent has been put into commercial production.
Isopropylphenyl Phosphate(IPPP50)
Cas Number: 68937-41-7
Customs Code HS: 29199000
Tax Rebate: Current Isopropylphenyl Phosphate, Flame Retardant IPPP50 Tax Rebate Of 9%.
Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet To Play With 16 Tons), 1000KG / IB Barrel (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.
Isopropylphenyl Phosphate(IPPP50)Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP50 This Product Is Compatible With Vinyl Chloride, Nitrocellulose, Synthetic Resin And Natural Resin, Etc. Because Of The Above Advantages, Reofos Series In Industrial Production Is Widely Used: PVC Film As Flame Retardant Plasticizer, Reofos Increase In The Amount Of Oxygen Index Increased, Enhanced Flame Retardant. In The Rubber Industry Can Be Used As Chloroprene Rubber And Rubber Flame Retardant Plasticizer; In Other Industries Can Be Used As Lubricants With Extreme Pressure Additives And Digestion Of Cellulose Paint, Resin, Phenol Resin And Other Flame Retardants.
Isopropylphenyl Phosphate, Flame Retardant IPPP50 Use Is Also Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
The improvement of phosphorus phosphonate - phosphorus efficiency is the improvement of processing stability. DSC data indicate that its processing window is wider than the p-n system, red phosphorus and bromide system.
The heat release rate curve of the new phosphorus-phosphorus (p-p) system is similar to that of P- N. Flammability grade and hot wire performance are similar. For example, using the Exolit OP1400 system, the V0 level can reach the thickness of 0.4mm.
Relative Exolit OP 1400 tracking index (CTI), and other performance is remarkable, so especially suitable for the connectors, circuit breakers, switches, such as use of polyamide, the improved processing stability, no spray frost, the influence of mechanical properties of compounds can be neglected. The flame-retardant PA66 GF30 complex produces less hydrogen cyanide (HCN) in the p-p system, so the smoke toxicity index is much lower than the p-n flame retardation. The density of smoke is also low, so the system is suitable for railway and other transport applications. With Exolit OP 1400 fiberglass enhanced polyamide, LOI high and low in smoke density and toxicity, can reach the highest safe level of EN 45545 HL 3.
As mentioned earlier, polyamide 66 usually require polyamide flame retardant processing temperature resistant to around 300 ° C, but the processing temperature are also likely to achieve the high temperature of 340 ° C. When modified, if the additive thermal stability is insufficient, it is possible to produce polymer degradation, product formation and discoloration. The analysis of the differential scanning calorimeter (DSC) showed that phosphonate flame retardant with phosphorous addition enhanced the processing window of the PA66 complex above all other flame retardant PA66.
Many of the modified plants have already started producing products containing Exolit OP 1400. Over the past 10 years, halogen-free, accelerant, great progress has been made in the PA6 and PA66 become one of the main production material, electrical parts at the same time of meet safety regulations comply with the important trend to electrical and electronic equipment, especially the thin wall. This also enables the continuous stable polyamide polymer as the most cost-effective composite material. Exolit 1400 will help the electronics and electrical equipment industry continue to grow.
