What tyre chemical products do you offer?

We offer a range of rubber chemical products essential for tyres and other rubber related products such shoes, belts and hoses. The products we produce comprise mainly rubber accelerators, anti-scorching agents, anti-oxidant TMQ & 6PPD and insoluble sulphur.

What are the degradation products of rubber?

Typical degradation products include dipentene and isoprene for natural rubber, while styrene, butadiene, vinyl cyclohexene, cyclohexenylbenzene and phenyl [4.4.0]bicyclodecene have been used as a marker for styrene-butadiene rubber.

Which processes are underrepresented for tire pollution?

Atmospheric chemistry and transport are underrepresented processes for tire pollution. Tire chemicals are expected to be distributed on particulate matter in air. Air relevant transformation studies are required for various tire-derived chemicals. Property data is needed to assess fate of transformation products of tire compounds.

Are hmmm & 1-3-diphenylguanidine a transformation product of tire wear additives?

This is especially relevant as it has recently been shown that many transformation products of tire wear additives (e.g. HMMM and 1,3-diphenylguanidine (Johannessen et al., 2021c, 2021a) are present at elevated concentrations in aquatic environment.

How can Lanxess help tire manufacturers reduce their environmental footprint?

Is phenylguanidine a transformation product of DPG?

These include 1,3-dicyclohexylurea, N-methyl-dicyclohexylamine, 1-cyclohexyl-3-phenylurea, and phenylguanidine, which is likely a transformation product of DPG (Du et al., 2020; Peter et al., 2018). Notably, N-methyl-dicyclohexylamine is also used in the production of plastic, pipies, agrochemicals, textile chemicals, and polyurethane foam.
