New solutions for the tire industry

• Innovative high-performance rubber additives
• Clean separation solutions for tire manufacturing
• Diverse reinforcement options for tires

Cologne – LANXESS’s Rhein Chemie business unit will be presenting its versatile solutions for the manufacture of tires at the Tire Technology Expo in Hanover. These include a wide range of environmentally friendly Rhenodiv release agents, Rhenomark tire marking paints, Rhenoshape tire vulcanization bladders, Rhenogran aramid-fiber masterbatches, and additives.

“The tire industry remains one of our most important markets,” says Dr. Dietmar Hoff, Head of Marketing Tire Products at LANXESS’s Rhein Chemie business unit. “In our Rubber Additives business line, additives for rubber compounds, release agents and tire curing bladders make a major contribution to our business results. Bladders with a permanent coating make the work even easier for tire manufacturers – they help make the production process far more efficient by removing the need for constant spraying of release agents.”

Cleaner tire production due to silicone-free, washable and permanent release agents

Rhein Chemie provides tire manufacturers with innovative solutions for the production of high-quality tires. In the manufacture of sealant tires or low-noise tires, it is essential that the release agents applied or transferred to the blank are completely removed after vulcanization. This is important in order to ensure that the subsequently applied polymers or foams adhere. Rhein Chemie provides various solutions for this purpose.

In addition to traditional silicone-based products such as Rhenodiv BP-286 and Rhenodiv BP-2864, which are removed after vulcanization from the tires in mechanical washing systems or by means of laser technology, new, 100 percent silicone-free products such as Rhenodiv BP-166 and Rhenodiv BP-9500 are now available. These are even easier to wash off due to a new, water-soluble release agent. These products also meet the increasing requirement of car manufacturers to completely dispense with the use of silicones during the tire production process.

Permanently coated Rhenoshape bladders enable tire manufacturers to vulcanize tires with no additional release agents, eliminating the need to clean the vulcanized tires. Since the spraying process for tire blanks is no longer necessary, no contamination can occur – neither in critical tire areas nor at the workplace. Likewise, this technology ensures that no silicon is used in the tire production process.
