LyondellBasell Petrothene® GA837091 Linear Medium Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Extrusion Grade; Medium Density (MDPE)
Material Notes:	Applications PETROTHENE GA 837-091 is a broad molecular weight, medium density resin designed for extrusion and injection-blow molding. An antioxidant had been added to ensure thermal stability. Processing Techniques GA 837-091, unlike other linear medium or linear low density resins, takes advantage of its broader molecular weight distribution to provide extrusion characteristics well suited to the extrusion and injection blow molding processes. Of particular note are both the melt strength and the smooth, melt fracture-free surface of the resulting parison. Physical Properties This resin offers an intermediate level of stiffness rarely obtained without blending. The environmental stress crack resistance of GA 837-091 is outstanding. This product is from the former Equistar product line.
