Product Details:
Our production of FR301A halogen-free flame retardant is a highly efficient phosphorus and nitrogen system of flame retardants. PBT for its enhanced flame retardant has a very excellent flame-retardant effect and heat-resistant effect, containing 30% of the PBT fiber generally add 17-18 copies can v0. And can be used for halogen-free flame retardant TPU.
Its usage and dosage are as follows:
1: temperature design, PBT halogen-free flame retardant design of the maximum temperature of not more than 240 degrees, and with the shear force of the lasting and increase, the temperature must be forced downward trend. And must not have too much 45 degrees, 90 degrees shear block continuous shear. So as to ensure that the flame retardant is not decomposed by the shear heat and the direct heating of the temperature.
2: The production process of a small amount of decomposition of the smell is normal, the material of its melting point will be low, therefore, in the selection of other components of the material additives when the selection of the higher melting point of the material quasi. Such as PPA, 35BA40 as its toughening agent will be better, can greatly improve its melt index, enhance the processing performance of materials and injection processing performance.
3: The choice of lubricant; this product in the production process, ester lubricants will reduce the flame retardant effect. In order to enhance the processing properties of their materials, you can choose EBS, TAF and other ammonia-containing lubricant or silicone lubricant more appropriate. This product is ideal for both black and natural colors. Physical retention rate as FR301B, flame retardance is not much difference. But the color retention rate is the best. This product is very little dripping, the user may, according to their own discretion, the use of anti-dripping agent.
4: The basic formula: quality points;
PBT1401 44.5;
Fiber 30; 35BA40 6;
Antioxidant 1010 0.2;
Antioxidant 168 0.2; FR301A 17; TAF 1.5;
Talc (5000 mesh): 0.35 570 0.2
Anti-dripping agent 0.1
Mixing process: PBT, toughening agent weighing into the mixing hopper, adding coupling agent mixing, a minute. After adding antioxidants, lubricants, talc mix, about 1.5 minutes. Finally add flame retardant FR301A mix, about 2.5 minutes. (After adding FR301A, the mixing time shall not exceed 3 minutes.) The total mixing time is 5 minutes.
