Sulfenamides

Product Name:

Rubber Acceleartor DCBS (DZ)

Model:

NURCHEM DCBS

Description:

Provide a longer scorch time, longer cure time and lower modulus than CZ TBBS and MBS. Thus will require higher use level for equivalent physical properties; more often used in steel skim compounds for improved and adhesion

Product Name:

Rubber Accelerator CBS (CZ)

Model:

NURCHEM CBS

Description:

CHEMICAL NAME: N-Cyclohexyl-2-Benzothiazolesulfenamide CAS NO.: 95-33-0 CZ is a primary amino based accelerator giving good scorch safety, a fast cure and good modulus development in a variety of general purpose polymers. It is the most active sulfenamide in EPDM

Product Name:

Rubber Accelerator NOBS (MBS, MOR)

Model:

NURCHEM NOBS

Description:

MBS provides extended scorch safety and good green stock storage stability compared to CBS or TBBS. It is recommended for applications where extended scorch safety is required such as thick extrusions. Stock with high loading of furnace blacks such as ISAF and SAF. Its long scorch delay is also advantageous in injection or transfer molding operations.

Product Name:

Rubber Accelerator TBBS (NS)

Model:

NURCHEM TBBS

Description:

Provides fast cure and high modules development in NR SBR BR and blends. Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products. Can be used to effectively replace MBTS/DPG systems TBBS may give equal modulus to CBS or MBS when used as a 10% lower level.

Product Name:

Rubber Accelerator OTOS

Model:

NURCHEM OTOS

Description:

Delayed-action primary accelerator and scorch-modifying secondary accelerator.
