Product Description
Organic phosphorus flame retardant DTFR-636 This product is widely used in polymer materials such as polyurethane foam, unsaturated polyester resin, epoxy resin, etc. The self-extinguishing, low temperature resistance, plasticity, ultraviolet stability and resistance of its products The electrostatic properties are better than those with other flame retardants. 1. Application in rigid polyurethane foam sandwich panel, casting and spray forming Rigid polyurethane foam, as an energy-saving, heat-insulating and anti-corrosion material, is widely used as an insulation and energy-saving material in petroleum, chemical, cold storage, construction and other industries. The use of experiments shows that the addition of 6-15 parts of DTFR-636 can achieve different flame retardant levels. DTFR-636 can also achieve satisfactory flame retardant effect on polyurethane soft foam and soft foam composite materials. 2. Applied to unsaturated polyester resin DTFR-636 is used in unsaturated polyester resin, has good compatibility, excellent flame retardancy, can be made into flame retardant glass steel and flame retardant transparent glass steel products. The synergistic effect of DTFR-636 and aluminum trihydrate added to the product can reduce the production cost and obtain high-quality products with low toxicity, low smoke and high flame retardant performance. The addition of DTFR-636 flame retardant has a good flame retardant effect in epoxy resin and furan resin. DTFR-636 is synergistic with antimony trioxide and aluminum trihydrate. Add 15-30 parts of DTFR-636 to obtain epoxy resin flame retardant potting compound with high flame retardant properties. 3. How to use DTFR-636 flame retardant must be used now and added. It should not be stored for too long after being mixed with polyurethane foam and combined polyether.
