PROPERTIES:
Amber transparent liquid,Light White powder/granule.
APPLICATION:
1.Used as secondary accelerator together with sulfenamide,thiazole,thiuram,carbamate and guanidine in the sulfur vulcanizaation of EPDM.synthethic diene rubbers and natural rubber;
2.Form no secondary amines which can be converted to carcinogenic N-nitrosamines;
3.Highly soluble and dispersible in all conventional types of rubber,especially in EPDM,and is characterized by rapid vulcanization;
4.When optimum proportions are used,accelerator systems for NR demonstrate excellent reversion and heat aging resistance;
5.With its excellent non-blooming and non-staining characteristics,its particularly suitable for colored,transparent or translucent compounds;
6.Good processing safety the green compounds have a good shelflife.
