Lupox SG5200 PBT原装新料韩国LG公司相关型号及产品介绍,应用介绍:
PBT的工艺特性
PBT具有明显的熔点,熔点为225~235℃,是结晶型材料,结晶度可达40%。
PBT熔体的粘度受温度的影响不如剪切应力那么大,因此,在注塑中,注射压力对PBT熔体流动性影响是明显。
PBT在熔融状态下流动性好,粘度低,仅次于尼龙,在成型易发生“流延”现象。
PBT成型制品各向异性。PBT在高温下遇水易降解。
Technological properties of PBT, PBT, has obvious melting point, melting point is 225 ~ 235 ℃, is a crystalline material, crystallinity of 40%.PBT melt viscosity is affected by temperature as well as shear stress is big, therefore, in the injection molding, injection pressure of PBT melt liquidity effect is obvious.PBT in molten state good liquidity, low viscosity, nylon, second only to "stretch" occur in the molding.PBT, molding products anisotropy.PBT, easy degradation under the influence of water at high temperature.

常用的无卤阻燃剂二乙基次磷酸铝和三聚氰胺磷酸盐,同时添加聚醚酰亚胺。聚醚酰亚胺具有耐热性好、弯曲与拉伸强度高等特点,并达到UL94 VO级,因此在PBT中亦起到阻燃作用。首先,通过UL94测试来表征阻燃性。之后,采用TGA与FHR分析这些阻燃剂的作用机理,并对阻燃测试结果进行分析。另外,还采取不同的阻燃剂以观察它们之间的协同效应。实际上,PBT+A1Pi以及同时添加聚醚酰亚胺(Uhem)的样品其阻燃性能最好,是由于A1Pi与Uhem在分解后会产生更多的残渣,从而提高了聚合物的阻燃性。
The commonly used halogen-free flame retardants diethyl aluminium phosphate and melamine phosphate, at the same time adding polyether imide.Polyether imide has good heat resistance, bending and tensile strength is high, and achieve UL94 level VO, so also in PBT flame retardant effect.First of all, through the UL94 testing to characterization of flame retardancy.After using TGA and FHR analysis the mechanism of flame retardant, and the flame retardant test results were analyzed.Also, take different flame retardants to observe the synergistic effect between them.In fact, PBT + A1Pi and at the same time adding polyether imide (Uhem) samples of the flame retardant performance is the best, is because A1Pi and Uhem will produce more residue after decomposition, so as to improve the flame retardancy of the polymer.
