A new line of non-hygroscopic thermoplasticvulcanizates (TPVs) has been developed for applications requiring both color and photo-oxidative stability. These products span the hardness range from 20A to 520 and offer superior oil resistance and compression set. In this paper, we will discuss the properties of the new TPVs, including non-hygroscopicity, oil resistance, compression set, color consistency, colorability, non-pinking and weatherability.
