Effective April 1, the cost of rubber chemicals supplied by Lanxess AG will increase by around 15% to 25%, depending on product and region. The German company said its Rubber Chemicals business unit is raising prices in response to "steeply rising raw material costs" and the increase affects almost the entire product range of antioxidants (Vulkanox, Vulkazon), accelerators (Vulkacit) and specialty chemicals (including Renacit, Cohedur, Perkalink and Vulcuren).
