DOW CORNING® MB25-502 MASTERBATCH by Dow Corning is a pelletized formulation containing 25% of a high molecular weight (HMW) siloxane polymer dispersed in low density polyethylene (LDPE). It is designed to be used as an additive in polyethylene compatible systems to provide benefits such as processing improvements. Dow Corning® MB25-502 Masterbatch by Dow Corning enhances processing and modified surface characteristics. It can cost effectively boost throughput by upto 110 percent and improves slip properties as well as reduces energy consumption and waste. Improves the lubricity and flow of thermoplastics. It also avoids die build-up and die pressure that require frequent interruptions for cleaning. It is suitable for use in low-density PE (LDPE), linear low-density PE (LLDPE) and cross-linked PE (XLPE) and extrusion process. DOW CORNING® MB25-502 MASTERBATCH is used for polyethylene wire and cable insulation and jacketing. It is highly efficient at lower loadings (0.5 to 1.0 percent) and its suggested used level is 2-4%.
