Title: Teodora Doneva: Innovator in Thermoplastic Polyolefin Elastomer Compositions
Introduction
Teodora Doneva is a notable inventor based in Horgen, Switzerland. She has made significant contributions to the field of thermoplastic polyolefin elastomers, holding three patents that showcase her innovative spirit and technical expertise.
Latest Patents
One of her latest patents is for a powdered thermoplastic polyolefin elastomer composition for slush molding. This invention relates to a thermoplastic polyolefin elastomer composition in powder form, which includes an olefin block copolymer and optionally a high-density polyethylene (HDPE). The composition boasts a Shore A hardness greater than 75, a Tg less than -45°C, and a distinct melting peak greater than 95°C. It also features a zero shear viscosity equal to or less than 1,200 Pa-s and a particle size distribution where 85 percent of the particles fall between 150 microns to 420 microns. This composition demonstrates excellent pulverizing and flow characteristics at temperatures of 5°C or less than the distinct melting peak of the olefin block copolymer. Additionally, it has applications in slush molding or rotational molding for various products, including automotive interiors, sporting goods, and packaging materials.
Another significant patent by Doneva is for a cross-linkable polyolefin composition for formed textured skin applications. This invention involves a flexible polyolefin composition that can be extruded into a sheet and formed into a textured skin for applications such as automobile interiors. The composition comprises 60 to 75 weight percent of one or more silane cross-linkable polyolefin polymers, a moisture-cure condensation catalyst, and 25 to 40 weight percent of one or more polyolefin polymer elastomers. The extruded sheet can be formed into a textured skin, preferably through positive vacuum forming.
