Product introduction
The additive halogen free flame retardants are used for LSI packaging, epoxy resin molding compounds, copper clad laminate, powder coatings, LED luminescent tubes and other polymer materials, which are compatible with EU REACH regulations and ROHS standards. The flame retardancy of UL-94 VO can be achieved, and the flame retardancy is much better than that of the traditional flame retardant system.

Flame retardancy
Phosphazene compounds with P and N double bond is a kind of alternate arrangement of inorganic compounds exist in the chain structure, circular or linear structure on the phosphorus atom access phenoxy that the product introduction, phenoxy phosphazene compounds become the product of the combination of inorganic compounds and organic compounds, is a kind of good halogen-free environment-friendly flame retardant.
Phosphonitrile flame retardant has good synergistic effect between phosphorus and nitrogen, and has higher thermal decomposition temperature and flame retardancy effect, less smoke and toxic gas. An environment-friendly flame retardant material can meet the requirements of European Union RollS directive and WEEE directive.
Performance mechanism of flame retardant phosphazene compounds for the comprehensive effect of four kinds of ways, decomposition of phosphazene heat endothermic cooling mechanism; the heat generated by the decomposition of phosphoric acid, phosphate and polyphosphate, can form a layer of protective film on the surface of polymer volatile material, cut off the air, this is the isolation membrane mechanism; simultaneous heating after the release of carbon dioxide, ammonia, nitrogen, water vapor and other gases, this is not the dilution mechanism; combustion gas blocking the supply of oxygen to achieve synergistic and cooperative purpose, and polymer combustion with PO group is formed, it can be used with the flame area in H - and HO - reactive groups combined to suppress the flame, which is to terminate the chain reaction mechanism. Because of the above synergistic effect, the system shows good flame retardancy.
Benzoxonitrile is used in combination with other flame retardants, such as magnesium hydroxide and aluminum hydroxide, and has good synergistic and synergistic flame retardancy. In addition to less complex flame retardant under the condition of high oxygen index, smoke suppression of fire retardant system, showing good incombustibility and excellent flame retardant properties, which not only reduces the cost and mechanical properties of flame retardant, the system has been improved, such as elongation and impact strength were significantly increased.
Organic phenoxyphosphazene has excellent properties of inorganic and organometallic polymer, is a kind of good elastic body, a lower glass transition temperature, melting point and the polymer materials have certain relation, in the mixed molten refining processing temperature under the plasticizing effect, can promote the Mg (OH), AI (OH) dispersed in the base material, so it can play a great flame retardant synergism, also has certain toughening effect on flame retardant system, breaking elongation and impact strength increased significantly, while the tensile strength can be maintained.
Main features:
The six phenoxy cyclophosphonitrile is a new type of nitrogen and phosphorus organic heterocyclic polymer structure. It is a new high-efficiency, environmentally friendly halogen-free brominated flame retardant. Its product name includes: phosphonitrile flame retardant, SPB-100, KP735NA and so on. The product has the following notable characteristics.
1. the flame retardancy efficiency is higher (13.4% phosphorus content, nitrogen content 8%), nitrogen and phosphorus synergy, multi mechanism synergistic flame retardant, the flame retardant effect is better.
2. excellent resistance to hydrolysis, moisture resistance, aging resistance.
3. the heat resistance is good, the thermal stability is high (the melting point is above 112 C, no plasticizing effect, the effect on TG is small, the initial decomposition temperature is over 350 C).
4. the solubility of organic solvents is good.
5. electrical performance is good.
Six phenoxy cyclotriphosphazene as traditional organic phosphate additives (PX-200, RPP, BPP, SP-703, SP-607H etc.) the upgrading of products and DOPO, creatively solve the latter hydrolysis resistance and heat resistance can not be applied to the electronic packaging industry CCL, capacitance increasing challenges.
