無鹵阻燃劑巨頭德國科萊恩公司新推出于聚烯烴體系的膨脹型無鹵阻燃劑Exolit^?AP766。該新產(chǎn)品充分結(jié)合了科萊恩公司業(yè)內(nèi)并獨(dú)享的“高聚合度、高純度、 晶形II、精細(xì)微膠囊化包覆及協(xié)效改性”等多項(xiàng)顯著技術(shù)優(yōu)勢。

Exolit^?AP766可應(yīng)用于PP、PE、PP共聚物、PP共混物的注塑及擠出制件的無鹵阻燃改性（包括無鹵阻燃PP薄片等）。

Exolit^?AP766也可以應(yīng)用于玻纖增強(qiáng)聚丙烯體系的無鹵阻燃。

相比Exolit^?AP760等，Exolit^?AP766的熱穩(wěn)定性更為（T_d> 275^oC)、加工窗口更寬、抗水性、阻燃效率更高。UL 94 V-0/1.6mm, 所需添加量明顯減少，從而綜合物性得以地保持與改善。

Applications
Applications Exolit AP 766 (TP) was developed especially for use in polyolefins. It is suited for PP, PE, PP copolymers and PP blends for injection moulding and extrusion applications as well as for glass-fibre-reinforced grades. Formulation In PP homopolymer and glass-fiber-reinforced PP, a dosage of 20 to 22 % (by wt.) Exolit AP 766 (TP) is usually sufficient to obtain the UL 94 V-0 classification at 1.6 mm together with GWFI 960°C and GWIT 800°C. The mechanical properties of plastics are slightly altered by addition of Exolit AP 766 (TP) due to the filler like type of the flame retardant. Subject to the polymer grade, processing conditions and glass-fibre-reinforcement the dosage of the flame retardant may vary. Processing The optimum conditions for incorporating should be determined in each individual case. Care must be taken to ensure homogeneous dispersion of all components. Both single- and twin-screw extruders are suitable for incorporating the product. The temperature of the polymer melt should not exceed 250°C. To prevent degradation effects by high shear energy, it has proved an advantage to use machines of less shearintensive design. When a water bath is used for cooling the strands, it is advisable to keep the passage through the water bath as short as possible to permit optimum evaporation of any entrained water. In some cases, depending on production conditions, it may be necessary to dry the granules obtained. The mixing and processing methods customary in powder processing of polymers can be used with Exolit AP 765 (TP). The VDI Guideline 2263 “Prevention of dust fires and dust explosions” or the relevant national regulations must be observed.
Safety and Handling

Exolit AP 766 (TP) is non-hygroscopic. However, when stored in open container, the product can still absorb small amounts of moisture owing to the high surface area of the powder. Plastic granules containing Exolit AP 766 (TP) also absorb small amounts of water after processing, depending on storage conditions. It is therefore advisable to store plastic granules containing Exolit AP 766 (TP) in sealed containers at room temperature in a dry place. Partially emptied containers should be carefully resealed after use.
