POLYURETHANE-CONTAINING NON-FOAMED MOLDED BODY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240255403 titled 'POLYURETHANE-CONTAINING NON-FOAMED MOLDED BODY
The abstract describes a non-foamed molded body made of polyurethane with specific hardness and erosion rate characteristics.
- The molded body has a martens hardness of 1.0 N/mm or more at the surface closest to the center of gravity.
- Three points of martens hardness in a cross-section of the body satisfy a specific relational expression.
- The index value k from a scattering profile obtained by evaluating a characteristic x-ray from a cu tube incident on the surface region meets a specific relational expression.
- The erosion rate of the molded body is 0.6 μm/g or less when measured with spherical alumina particles of 3.0 μm diameter.
Potential Applications: - Automotive industry for impact-resistant parts - Construction industry for durable components - Sports equipment for high-performance gear
Problems Solved: - Provides a molded body with specific hardness and erosion rate characteristics - Ensures durability and longevity in various applications
Benefits: - Increased impact resistance - Longer lifespan of components - Improved performance in demanding environments
Commercial Applications: Title: "High-Durability Molded Body for Various Industries" This technology can be used in automotive, construction, and sports equipment industries for impact-resistant and long-lasting components.
Questions about the technology: 1. How does the specific martens hardness contribute to the durability of the molded body? 2. What are the implications of the low erosion rate in practical applications?
Original Abstract Submitted
the molded body is a non-foamed molded body including a polyurethane, wherein a martens hardness measured at a point on the surface of the molded body positioned at a shortest distance from the center of gravity g is 1.0 n/mmor more, and three points of martens hardness measured in a cross-section of the molded body satisfies a specific relational expression, wherein an index value k from a scattering profile obtained by allowing a characteristic x-ray from a cu tube to incident on a surface region to be evaluated of the molded body satisfies a specific relational expression, and wherein the molded body has an erosion rate e of 0.6 �m/g or less, which is measured with spherical alumina particles having an average particle diameter (d) of 3.0 �m in the surface region to be evaluated.
