POLYETHYLENE TEREPHTHALATE COMPOSITION |
摘要 |
<p>The present disclosure is concerned with reinforced flame retarded polyethylene terephthalate molding compositions which have good mold release properties upon being injection molded because they contain low molecular weight copolymer acids which may have been neutralized with selected metal cations. If these copolymer acids are used in sufficient amount they may also act as drip suppressant agents thus allowing the compositions to reproducibly obtain a UL-94 rating at 1/32 sec of V-O. When used in lower amounts in combination with other drip suppressants these low molecular weight copolymer acids provide both enhanced mold release and enhanced drip suppression. These compositions contain a flame retardant package sufficient to give the base polyethylene terephthalate resin a UL-94 rating at 1/8 sec of V-O when tested with just the flame retardant package. These compositions are preferably reinforced with glass or other fibers. The addition to these compositions of a compound bearing at least 3 terminal epoxy groups can improve the composition's physical properties and does improve their resistance to degradation due to thermal or hydrolysis exposure. These compositions are suitable for the injection molding of a wide variety of articles of commerce.</p> |
