DPG has been shown by the European Union to be toxic to aquatic life and is considered a reproductive toxin as it may cause fertility issues as well as being a skin irritant. The tire industry is seeking biobased, sustainable solutions that perform the same or better in their rubber formulations over the incumbent materials. NAUGARD BIO-XL™ accelerator has been demonstrated to be effective as a replacement for DPG. SI Group will present new data from a study in a specialty tread formulation for this product that indicates improved cure characteristics and tread performance

• Regulatory challenges facing the use of diphenylguanidin (DPG) in rubber cure systems
• How the bio-based accelerator NAUGARD BIO-XL from SI Group can be used to replace harmful DPG
• What options exist to fine-tune the cure characteristics when reformulating cure systems to be based on NAUGARD BIO-XL
