"Processes to produce a profile for extrusu00e3ode profile of a thermoplastic resin, and parareduzir fracture in fusion of a profile formadopor extrusion profile, and,The composition of resinapara profile extrusion.In a process for produzirum profile by profile extrusion of a thermoplastic resin, umamassa in fusion of the thermoplastic resin is extruded by means of a matrix, to form the profile.The process is melhoradoutilizando is a thermoplastic resin having an approximate composition of 99,95 about 98% by weight of amorphous polyester ousemicristalino and about 0.05 to about 2.0% by weight of umsal of zinc and an organic acid.The improvement doprocesso is by speed increase or decrease datemperatura a process of profile extrusion, now operating emuma maximum speed and / or temperature,With the experimentation defratura in fusion.When the fracture is present noprocesso melting extrusion profile, a method to reduce the fracture emfusu00e3o a profile is carried out by combining is about 99, 95 to 98.0% by weight of amorphous polyester or semicristalino and approximate 0.05 to about 2.0% by weight of a zinc salt of an organic umu00e1cido to form a fusion.Extruding into the dough is emfusu00e3o through a hole of a matrix in a temperature 's a speed to form an extruded article having a formatoe, then,The article paraformar abruptly cooled extruded profile.
