According to GlobalData’s company profile on OMV, Corrosion resistant fuel additives was a key innovation area identified from patents. OMV's grant share as of February 2024 was 50%. Grant share is based on the ratio of number of grants to total number of patents.
A recently granted patent (Publication Number: US11920018B2) discloses a process for preparing a semiconductive polymer composition. The process involves mixing a polymer component and additives at an elevated temperature to obtain a polymer melt, adding carbon black with specific characteristics, and extruding and pelletizing the resulting polymer mixture. The carbon black used in the process has defined physical properties such as mass pellet strength, pellet size, hardness values, and iodine adsorption number, ensuring the desired properties of the semiconductive polymer composition.
Furthermore, the patent claims specify additional characteristics of the carbon black, such as BET surface area and DBP oil absorption number, along with requirements for surface smoothness of the composition. The polymer component used in the process includes specific types of alpha-olefin polymers, homopolymers, or copolymers with defined comonomers. The composition's melt flow rate and cross-linking capabilities are also detailed in the claims, providing a comprehensive guide for preparing a semiconductive polymer composition with desired properties.
