    Abstract: High pressure injection apparatus (2) for addition of a liquid formulation into a melt stream comprises a first pump which is arranged to accurately meter the liquid formulation (including highly loaded formulations comprising solids comprising particles of relatively large size) and a second pump which boosts the pressure of the formulation to that of the melt stream into which it is to be injected. In an embodiment, the apparatus includes a tank (4) for initially receiving liquid formulation. The tank is subjected to ambient temperature and pressure and need not be stirred or otherwise agitated. The tank is arranged to deliver the formulation via pipe (6) into a first pump (8) (which may be a diaphragm pump or a progressing cavity pump). The pump is arranged to work at a pressure up to 120 bar to boost pressure. Downstream of pump (8), a pipe (10) is arranged to deliver formulation from the pump ()8 to a gear pump (12), driven by a motor (13). The gear pump acts to meter the liquid formulation. In an alternative embodiment, apparatus may include a progressing cavity pump to meter formulation and a gear pump to increase pressure. The apparatus may be used to inject a fluid formulation into a melted polymeric material.

    Abstract: A reservoir assembly (40) comprises a container (4), a support assembly (42) on which the container (4) is mounted and fixed and a rotary electric vibrator device (44) coupled to the support assembly (42). The container holds a shear thinning additive for a plastics material. The reservoir assembly is arranged so that on operation of the device (44), an appropriate frequency and amplitude of vibration is applied to the container (4) and, therefore, its contents.As a result, a liquid dispersion in the container is shear thinned and recovery of dispersion from the container is increased.

    Abstract: Un aparato de inyección para inyectar una formulación líquida en un polímero fundido a alta presión incluye un depósito que contiene formulación líquida a temperatura y presión ambiente que se dispone para alimentar por inundación el cuerpo de bomba 26 de una primera bomba de cavidad progresiva (bcp) 4. La primera bcp 4 se acciona por el motor 6 y se dispone para dosificar con precisión la formulación líquida en una segunda bcp 8 que se encuentra corriente debajo de la primera bcp y se dispone para incrementar la presión de la formulación líquida por 200 bares o más. Corriente abajo de la bomba 8 se encuentra una válvula de suministro 14 dispuesta para controlar el paso de la formulación líquida, a través de la salida 17, hacia la corriente polimérica fundida presurizada 75 que se encuentra presente en un extrusor 77.
