Anti-aging PP Masterbatch

Weather Resistance Masterbatch  LS-133W for  PP Nonwoven fabric  1. Introduction.  LS-133W masterbatch  is prepared from  processing  various high performance anti-aging additives with PP carrier resin. It has been specially designed for  weather resistance nonwoven systems,Website:, especially for outdoor applications . The LS-133W masterbatch  provides  excellent processing stability, exceptional  thermal oxidative stability , high light fastness,  and  outstanding weather resistance,  which improves the reliability and extends  the service  life of PP nonwoven fabric.  The major characteristics of LS-133W are as follows:  1) . Broad UV-band absorption, which is  ideal for UV-shielding applications,  effectively prevents degradation of  PP nonwoven fabric  in the presence of  heat, light, oxidation and other  environmental climate factors during  outdoor usages.  2). Feature an excellent dispersion of ingredients in PP nonwoven fabric,  leads  to high stability and endurance of the anti-aging agents.  3).  Melt flow properties matches well with PP nonwoven matrix resin and demonstrates  excellent compatibility, easily to achieve uniformly dispersed and blended resin composition .  4). Excellent processing stability, which avoids occasional yarn breaks during the spinning process,  ensure continuous production of PP spun and improve production efficiency. 2、Product Performance  Weathering Performance of 60g PP nonwoven fabric with LS-133Wxenon lamp aging Test (hours)ResultsRetentionoftensilestrength atbreakafteraging%72981689224084Retention of elongation at break after aging %72881687524062Color evaluation after aging(fastness)724-51684-52404-5Remark: the content of the LS-133SW is 2 % in the above product.
