Effect of Ethylene Bis Stearamide (EBS) Lubricant on Glass Fiber, ABS and SAN

Plastic Engineering

Glass fibers (GF) are the reinforcement agent used in most of the thermoset and thermoplastic based composites, as they create a good balance between properties and cost. The mechanical properties of the thermoplastic polymer changes gradually and drastically by addition of layers of glass fiber. The glass filled Acrylonitrile Butadiene Styrene (ABS) and Styrene Acrylonitrile (SAN) will suitable for home appliances and electrical parts applications. They show very high heat resistivity, dimensional stability and good thermal conductivity. The composite materials were produced by injection moulding process and compounding in side feeder Twin screw extruder of glass fiber, ABS resin and SAN melts were added by incorporating into the melt up to about 0 to 2 percent by weight of ethylene bis stearamide (EBS) lubricant. The specimens obtained from composite materials having different ratio of lubricant content were tested to determine tensile, flexural and impact strength, hardness, HDT/VST, MFR and also test FTIR. The EBS excellent lubricant for shear processing in melts of glass filled ABS and SAN. This invention relates to the improved shear processing and effect of mechanical property and thermal property of glass filled ABS and SAN melts.
