Previous versions of the material included organic slip additives, but those were replaced with DuPont's silicone-based additives. An important aspect of the switch is that silicone is stable at high and low temperatures, which gives the material a stronger abrasion resistance and cracking resistance. Ultraviolet light stability was also improved to prevent discoloration.The benefit to consumers is a lower coefficient of friction — in other words, it will be easier to open and close vehicle doors, according to Christophe Paulo, DuPont marketing manager.
Paulo called the ingredient a long-lasting solution that will function the same after 10 years as it will brand new. He estimated that the thermoplastic vulcanizates will reach production vehicles in three years.
