  • Does natural rubber have antidegradants?
  • Natural rubber already contains naturally occurring antioxidants that protect the polymer from oxidation. One of the key properties of antidegradants (antioxidants and /or antiozonants) is their solubility in the rubber matrix. The faster the rate of bloom, the less soluble the antidegradant is in the polymer system.
  • What happened to rubber in the 19th century?
  • In the late 19th and early 20th centuries, articles made from rubber had very poor weathering characteristics. Natural rubber was the only elastomeric polymer available for commercial use at that time. Articles made from natural rubber would soon become soft and tacky. They would no longer be serviceable.
  • What are standard-verified tire tread wear particles (Twps)?
  • Standard-verified TPs were quantified in roadway-impacted environmental samples, with total concentrations of 130 ± 3.2 μg/g in methanol extracts of tire tread wear particles (TWPs), 34 ± 4 μg/g-TWP in aqueous TWP leachates, 2700 ± 1500 ng/L in roadway runoff, and 1900 ± 1200 ng/L in roadway-impacted creeks.
