Abstract:
1. A high flow polyvinyl halide compound for use in injection molding and having a melt flow index, comprising: (a) polyvinyl halide resin having an inherent viscosity of from about 0.58 to about 0.78 dl/g, as measured by using 0.2 grams of resin in 100 ml of cyclohexanone at 30 degrees C. by ASTM D 1243; (b) phosphite flow modifying stabilizer; (c) hydrotalcite flow modifying stabilizer; (d) organometallic stabilizer; and (e) lubricant, wherein the polyvinyl halide resin has a K value ranging from about 52 to about 60, and wherein the melt flow index of the compound is at least 20% higher than that of the compound without presence of the phosphite flow modifying stabilizer and the hydrotalcite flow modifying stabilizer as measured by ASTM 1238 using 21.6 kg.
