  VAROX^® DCBP-50 Paste, Organic Peroxide Crosslinking Agent for Silicone Rubber, Bis (2,4-dichlorobenzoyl) peroxide, 50% in silicone oil

          VAROX DCP
Crystalline powder organic peroxide crosslinking agent for NR, IR, SBR, BR, NBR, EPDM and CR. Crosslinking agent for PE, POE, EPR, EVA, VAE and Silicone.

          VAROX DCP-40C
VAROX DCP-40C on calcium carbonate is preferred over the straight peroxide (VAROX DCP) for many compounds. Dosage should be approximately twice the amount for VAROX DCP. Non-sulfur curing agents for NR, IR, SBR, BR, NBR, EPDM and CR. Crosslinking agent for PE, EPM, Silicone, EVA and VAE.

          VAROX DCP-40C-SP2
The same as Varox DCP-40C, but with improved scorch protection for quicker mixing cycles, enhanced mold flow and quicker molding cycles.

          VAROX DCP-40KE
VAROX DCP-40C on Kaolin clay is preferred over the straight peroxide (VAROX DCP) for many compounds. Dosage should be approximately twice the amount for VAROX DCP. Non-sulfur curing agents for NR, IR, SBR, BR, NBR, EPDM and CR. Crosslinking agent for PE, EPM, Silicone, EVA and VAE.

          VAROX TBPB
Organic peroxide crosslinking agents for Silicone and other elastomers. Effective in the temperature range 132 to 173^°C (265 to 345^°F).

          VAROX TBPB-50
Organic peroxide crosslinking agents for Silicone and other elastomers. Effective in the temperature range 132 to 173^°C (265 to 345^°F). 50% Varox TBPB on an inert carrier.

          VAROX VC-R
Non-sulfur curing agent for NR and SR. Organic peroxide crosslinking agent for PE, CPE, EPDM, EPM, Silicone, EVA and VAE. Provides excellent compression set resistance.

          VAROX 130-XL
45 - 48% VAROX 130 on an inert carrier.

          VAROX 230-XL
Organic peroxide crosslinking agent for elastomers such as polybutadiene, CPE and EPDM. 40% assay on an inert carrier.

          VAROX 230 XL-SP
Peroxyketal crosslinking agent for elastomers such as polybutadiene, CPE and EPDM. Provides fast action times at given temperatures than dialkyl peroxides. VANOX 230 XL-SP provides improved scorch protection over VAROX 230-XL.

          VAROX 231
Vulcanizing agent for CPE, EPDM, EPM, NBR, SBR and silicone. Very effective at low curing temperatures. Also, as crosslinking agent for PE and EVA. Recommended curing temperature 275-350^°F.

          VAROX 231-XL
VAROX 231 at 40% assay on an inert carrier.

          VAROX 231 XL-SP
Peroxyketal vulcanizing agent for SBR, VBR, EPDM, EPM, CPE and silicone. Very effective at lower curing temperatures. Crosslinking agent for PE and EVA. Recommended curing temperature is 135 to 175^°C. VAROX 231 XL-SP is a more scorch resistant version of VAROX 231 XL.

          VAROX 802-40C
40% assay VAROX VC-R on a calcium carbonate carrier.

          VAROX 802-40C-SP2
The same as VAROX 802-40C, but with improved scorch protection for quicker mixing cycles, enhanced mold flow and quicker molding cycles.

          VAROX 802-40KE
40% assay VAROX VC-R on a Kaolin clay carrier.

          VAROX 802 SP-40MB Pellets
VAROX 802 SP-40MB Pellets is a new Scorch-Protected evolution of the easily dispersible VAROX 802-40MB. It is a 40% extended grade masterbatch of EPM + calcium carbonate. In a standard EPDM compound, scorch time measured at 125^°C is 3 times longer that the traditional VAROX 802-40C.
