Mineral MB Description ADFIL 230 is a polyolefin based concentrate containing a special mineral component designed for use in PE film and sheet. It improves mechanical properties such as stiffness, falling dart impact, tear resistance with minimum negative effects on optical properties. So it might be applicable for transparent and/or glossy parts to improve productivity through down-gauging. Application ADFIL 230 is designed for ease of dilution and homogeneous mixing and is therefore suitable for direct addition using automatic dosing units or by pre-blending. Depending on the application and film / sheet structure it can be used from 5% to 25%.
