DOW™ LDPE SC 7642 Low Density Polyethylene Resin

What is DOW™ LDPE SC 7642 Low Density Polyethylene Resin?

Designed for high speed cast extrusion lines, where it provides excellent draw down, low neck-in and high melt stability with a good balance between stiffness and tear resistance. Due to its density, the coefficient of friction of films made with this product will be lower. In association with DOWLEX* resins, it gives films with a superior balance between machine and cross direction properties. This resin can be readily extruded using conventional cast film techniques, using melt temperatures between 200 and 270 °C.
