POLYPROPYLENE-BASED RESIN EXPANDED BEADS AND MOLDED ARTICLE THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240025093 titled 'POLYPROPYLENE-BASED RESIN EXPANDED BEADS AND MOLDED ARTICLE THEREOF
Simplified Explanation
The abstract describes an expanded bead made of polypropylene-based resin that has a through hole with an average diameter of 1 mm or less. The expanded bead has a closed cell content of 85% or more, with an average cell diameter of 50 to 300 μm. The inner surface portion of the bead, which extends along the inner peripheral surface, has an average cell diameter of 5 to 150 μm, smaller than the average cell diameter of the expanded bead.
- The expanded bead is made of polypropylene-based resin.
- It has a through hole with an average diameter of 1 mm or less.
- The bead has a closed cell content of 85% or more.
- The average cell diameter of the expanded bead is 50 to 300 μm.
- The inner surface portion of the bead has an average cell diameter of 5 to 150 μm, smaller than the average cell diameter of the expanded bead.
Potential Applications:
- Packaging materials
- Insulation materials
- Lightweight construction materials
Problems Solved:
- Provides improved insulation properties
- Offers lightweight alternatives to traditional materials
- Enhances packaging efficiency and protection
Benefits:
- Improved thermal insulation
- Reduced weight for transportation and handling
- Increased durability and protection for packaged goods
Original Abstract Submitted
an expanded bead of polypropylene-based resin formed with a through hole that is defined by an inner peripheral surface and that has an average hole diameter of 1 mm or less. the expanded bead has a closed cell content of 85% or more, an average cell diameter of 50 to 300 �m and an inner surface portion that extends along the inner peripheral surface that has an average cell diameter of 5 to 150 �m which is smaller than the average cell diameter of the expanded bead.
