New Sulfur Donor Accelerator

1. It is a FDA approved vulcanization accelerator for use in NR, synthetic polyisoprene and NBR.

2. The vulcanizates obtained with diisopropyl xanthogen polysulphide are transparent and free from copper staining.

3. SPchem AC-100 also acts as a sulfur donor used in natural and synthetic rubber (including EPDM).

4. It is recommended for use as a primary and secondary accelerator in the presence of low levels of sulfur.

5. AC-100 synergies most effectively with other accelerators particularly TBzTD, MBTS and TBBS either in the presence or absence of elemental sulfur.

6. Can be used in low-temperature cure.

Application：

1. SPchem AC-100 is widely used in NR, IR, NBR, EPDM, IIR, Latex and adhesion agent.

2. When used in molded products (such as NR and Synthetic Polyisprene ), with sulfur 1.2-1.6phr, it is recommended to add AC-100 1.2-2.0 phr and TBzTD or MBT 0.2-0.4 phr.

3. In the sulphur donor cure system of heat-stable and low compression set vulcanizates (black filled NR, Polyisoprene and NBR), it is recommended to use AC-100 1.0-2.0 phr together with TMzTD 1.8-2.2 phr and TBBS 0.75-1.0 phr.

4. AC-100 can be used as an emulsion and bring the pre and post vulcanised NR latex with good physical properties.

5.  In the application for Carboxylated nitrile latex, AC-100 is also recommended to be used as accelerator (emulsion), with dosage 1.0-1.2 phr.
