1. Introduction of masterbatch di silicone
Thermoplastic elastomers (TPE) are widely used in various fields due to their combination of rubber elasticity and plastic processing convenience. The smoothness of the hand feel is one of the important sensory characteristics of TPE materials, which directly affects the user experience of the product. Silicone masterbatch, as an efficient lubricant additive, is increasingly being valued for its application in improving the smoothness and feel of TPE materials. This article reviews the current application status and potential mechanisms of silicone mb in the study of tactile smoothness of TPE materials.
introduction
The smoothness of TPE material is one of the key indicators for measuring its product quality, especially in the fields of daily necessities, medical equipment, and automotive interiors. Silicone mb has become an important additive for improving the hand feel of TPE materials due to its excellent lubrication performance and thermal stability.
2. Characteristics of silicone masterbatch
Silicone masterbatch is made by mixing ultra-high molecular weight polydimethylsiloxane with a plastic carrier, and has the following characteristics:
High thermal stability: suitable for high-temperature processing.
Excellent lubricity: reduces internal friction of materials and friction between materials and processing equipment.
Good dispersibility: evenly dispersed in TPE matrix to avoid local over lubrication.
Environmental safety: non-toxic, non corrosive equipment, non polluting products.
The influence of silicone mb on the smoothness and feel of TPE
Surface performance improvement
The addition of silicone masterbatch can significantly improve the surface properties of TPE materials, giving them a finer and smoother texture. This improvement is mainly due to the uniform lubricating film formed by silicone mb on the surface of TPE.
3. Smooth performance improvement mechanism of silicone masterbatch
The dispersion of silicone masterbatch in TPE forms a microscopic lubrication network, and when the material surface is touched, these lubrication points provide a lower friction coefficient, thereby achieving a smooth hand feel.
experimental study
Experimental studies have shown that by adjusting the amount of silicone masterbatch added, the tactile smoothness of TPE materials can be optimized. Adding an appropriate amount of silicone masterbatch can balance the mechanical properties and tactile characteristics of the material.
In practical applications, silicone mb is widely used for the modification of TPE materials, such as in the production of automotive interior parts with good hand feel, mobile phone protective cases, and other products.
Silicone masterbatch, as an effective additive, significantly enhances the tactile smoothness of TPE materials by improving their surface properties and reducing their friction coefficient. Future research should further explore the optimal addition amount and dispersion technology of silicone mb in different TPE systems to achieve better product performance and user experience.
With the continuous improvement of the requirements for the smoothness of TPE materials, the application of silicone mb will become more widespread. Future research can focus on the synergistic effect of silicone masterbatch with other additives, as well as further improving the dispersibility and lubrication effect of silicone masterbatch in TPE through nanotechnology.
