20210205839 · 2021-07-08 ·

In a dipping process using thermoplastic rubber (TPR), an object is dipped into melted TPR, removed, and dried in order to provide a TPR coating over the object. The underlying object may be colored with a pattern or illustration and dipped into transparent TPR, or a dyed TPR may be used to provide color to the object. An exemplary use is the manufacturing of pet toys with a TPR coating. However, the process is suitable for use with a variety of materials in a variety of applications, such as providing an insulating coating for wires, a grip for writing utensils, or any other application in which a TPR coating would be useful.
