What proportion of DONOR is most suitable for polypropylene plants using the liquid-phase bulk method? (1: Ensure that switching product grades is not affected by any issues; 2: Also ensure that the DONOR metering pump operates stably without fluctuations.) Please ask friend Haichuan to give some advice. QQ: 359995086

You just need to switch from a low-concentration DONOR to a high-concentration one according to the production grade; of course, using 30% is the more common approach

We use 1 mmol/ml

25–30% is the commonly used ratio; pure material is used when producing copolymers
