Abstract
Description
Technical Field
[0001] The invention relates to the field of thermoplastic elastomers, and in particular to a TPE micro-foamed mouse and keyboard wrist pad material. Background Art
[0002] TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material with high strength, high resilience, injection molding processability, wide application range, environmental protection, non-toxicity, safety, and excellent colorability. TPE material is soft to the touch, does not require vulcanization, can be recycled to reduce costs, can be secondary injection molding, coated with PP, PE, PC, PS, ABS and other base materials, or can be molded alone.
[0003] Traditionally, when using a mouse and keyboard, the wrist is basically unprotected. When the user operates the mouse and keyboard for a long time, the user's wrist will often feel tired very easily, which is very detrimental to the user's health. The existing wrist guard materials or sponge wrist pads have the defects of large deformation and inability to provide effective support, which still cannot solve the problem of wrist fatigue caused by long-term computer use. The wrist pad made of TPE material can remain soft and comfortable when using the computer, and the effective support for the wrist is also greatly improved, thereby effectively relieving wrist and shoulder fatigue. However, as people's requirements increase, the defects of existing TPE materials have gradually emerged, such as poor heat resistance, poor compression rebound, poor aging resistance, etc. Therefore, it is more important to have a TPE wrist pad material that is resistant to high temperatures, has high resilience and good aging resistance.
