Latest Patents
One of Hans M Rombrecht's latest patents focuses on flame-resistant, thermoplastic polyurethane elastomers. This invention involves a flame-retardant additive package that includes antistatic or electrically conductive thermoplastic polyurethanes. The specific formulation contains carbon black with a surface area determined by the BET method ranging from 600 to 1200 m²/g. These materials exhibit a dibutylphthalate absorption number of 300 to 450 cm³/100 g, a pour density of less than 250 kg/m³, and an average particle size of less than 50 nm. The incorporation of carbon black into the thermoplastic polyurethane is achieved through a continuous sheet method at temperatures below the primary melt peak for the crystalline rigid segments. The resulting products are suitable for applications such as films for flat heating elements, antistatic hoses, cables, and profiles.
