Abstract:
Injection apparatus for injecting a liquid formulation into a molten polymer at high pressure includes a reservoir containing liquid formulation at ambient temperature and pressure which is arrange to flood-feed pump body  26  of a first progressing cavity pump (pep)  4 . The first pep  4  is driven by motor  6  and is arranged to accurately meter the liquid formulation into a second pep  8  which is downstream of the first pep and is arranged to increase the pressure of the liquid formulation by 200 bar or more. Downstream of pump  8  is a delivery valve  14  arranged to control passage of liquid formulation, via outlet  17 , into pressurised molten polymer stream  75  which is present in an extruder  77.

Claim (Index 15):
Apparatus according to  claim 1 , wherein said apparatus is provided in combination with a melt processing apparatus, wherein said outlet of the apparatus for injecting is in fluid communication with an inlet via which fluid formulation can be introduced into a melt stream produced by said melt processing apparatus.
