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
