| Retarder SAX |
 |
Retarder SAX is composed of 90% technical salicylic acid/ 10% light paraffinic oil and is utilized as a vulcanization inhibitor for SBR and Natural Rubber compounds.
It is especially effective with thioazole, thiazoline and thiuram accelerator systems to prevent scorching at processing temperatures.
The recommended level of usage is approximately 0.5 phr.
A slight phr adjustment may be necessary to achieve the desired processing safety.
Retarder SAX is also recommended as an accelerator for mercaptan type polychloroprenes (M Bayprens or W Neoprenes).
1-2 phr of Retarder SAX in "gum" of lightly loaded "M" or "W" type polychloroprenes produces vulcanizates with high modulus and high elongation to break.
Retarder SAX is also effective in lead press cured mineral filled "M" or "W" type polychloroprenes compounds where sulfur cannot be tolerated.
Retarder SAX is not recommended in black filled stocks due to potential scorch reductions. |
