Product Description

Dipentamethylene thiuram
hexasulfide
C12H20N2S6
M.W. : 384
CAS : 971-15-3
EINECS : 213-537-2
PROPERTIES:
NURCHEM DPTT-75 is the most active thiuram.
It is an effective primary or secondary accelerator or sulphur donor for use in IIR,
EPDM, NR, IR, SBR, CR, CSM, and particularly for NBR. For CSM, DPTT should be used together with MBTS to furnish higher safety in blending procedure. It also yields white rubber with excellent resistance against weathering. With NR and synthetic rubbers it vulcanises without sulphur at low temperatures and leads to products with good physical properties and superb resistance against ageing.
NURCHEM DPTT-75 is effective at low and high temperatures. It is particularly suitable for light-coloured stocks.

Compared to a traditional EVM/EP(D)M binder, NURCHEM DPTT-75 allows :
l         Dust free products with a high level of filtration up to 38 μ.
l         Tack free products at room temperature.
l         Lower Mooney viscosity, improving quality of dispersion.
l         Scrap rate reduction thanks to filtration.
l         Wider compatibility with other elastomers.
