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 (pcp) (4). The first pcp (4) is driven by motor (6) and is arranged to accurately meter the liquid formulation into a second pcp (8) which is downstream of the first pcp 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).
