scorch retarder ctp(pvi)
In many compounds PVI gives a linear response between Mooney scorch and dosage level. It is therefore possible to adjust processing safety of a compound by changing the dosage of PVI. PVI is normally used at levels from 0.1 to 0.4 phr. Higher levels may give a slightly reduced cured modulus.
WESTCOâ„¢ MBT is a primary accelerator for natural and synthetic rubbers with excellent low temperature curing properties. It may be used in non-staining and non-black vulcanizates. It provides anti-scorch protection in sulfurless rubber compounds.

The research aim is mainly to investigate the effectiveness of natural antioxidant (NA) obtained from oil palm leaves (Elaeis guineensis) as an aging retardant in natural rubber (NR) vulcanizates. Comparison of NA with other commercial antioxidants, trimethyl quinoline (TMQ) and butylated hydroxy toluene (BHT), is investigated.
