Title: Innovations of James J Henry

Introduction

James J Henry is a notable inventor based in Downingtown, PA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced thermoplastic materials. With a total of 11 patents to his name, Henry continues to push the boundaries of innovation.

Latest Patents

One of his latest inventions is the Non-solid core filament for 3-D printing. This invention relates to thermoplastic filament designed for use in 3-D printers, where the core of the filament is non-solid or mono-filament. The filament may contain a multitude of small micro-voids, forming a micro foam, or may have a foam-core structure, be hollow, or possess a monofilament core. This innovative filament is particularly beneficial when used with crystalline and semi-crystalline polymers, as it reduces the negative effects of filament voids caused by shrinkage during the cooling process.

Another significant patent is for Cross-linked thermoplastic polyvinylidene fluoride compositions. This invention involves polyvinylidene fluoride (PVDF) copolymer compositions that exhibit improved crosslinking efficiency and performance. The PVDF copolymer contains a high level of a fluorinated comonomer and has a high molecular weight, which is measured by the melt viscosity at 230°C and 100 sec⁻¹. The composition can be effectively cross-linked with a low level of radiation, making it useful in high-temperature applications such as automotive wire and cable, as well as heat shrink tubing.
