Polymerization of vinylchloride:
PEROXAN BCC-40 W may be used in polymerization and copolymerization of vinylchloride in mass or suspension processes, usually in combination with other peroxides of varying degrees of activity to increase reactor efficiency.
Reasons to use a water based peroxide suspension are the following:
- Enhanced safety
- Solvent free. No contamination of the VCM recycle stream
- Enhancement of PVC purity
- Easy to use (pumpable) in "closed reactor technology"
- Easy to dilute with water
PEROXAN BCC-40 W is especially suitable for the production of micro-S-PVC.
Temperature range: 40 to 65°C
Dosing: 0,08 to 0,4 phr
PEROXAN BCC-40 W may also be used for the (co)polymerization of vinylidenechloride.
PEROXAN BCC-40 W is used for the curing of highly filled methacrylic resins, typically in combination with other curing agents of different reactivity, e.g. PEROXAN LP and PEROXAN PB.
PEROXAN BCC-40 W shows a high reactivity at elevated temperature, which is demonstrated by its low activation temperature, in combination with a relatively long pot life at ambient temperatures.
PEROXAN BCC-40 W is used in combination with a low reactive peroxide to ensure a good final cure. These peroxide combinations can successfully be used for those applications where a long gel time is required at room temperature in combination with a fast cure at elevated temperatures of 60°C to 140°C.
Applications areas can be cure-in-place-pipe (CIPP), pultrusion, filament winding, manufacturing of artificial marble.
Depending on working conditions, the following dosage level is recommended:
PEROXAN BCC-40 W as such: 2,0 to 4,0 phr
PEROXAN BCC-40 W as kicker peroxide: 1,0 to 2,0 phr
