Silicone masterbatch is a functional masterbatch.
It uses various thermoplastic materials as carriers and organic polydimethylsiloxane as active ingredients.
1.Definition and Composition
Definição:
Silicone masterbatch is a processing aid for thermoplastic materials, which is made by uniformly dispersing organic polysiloxane (i.e. silicone) in a thermoplastic carrier through a specific process.
Composition:
It is mainly composed of a carrier (such as thermoplastic materials such as PP, PE, ABS, etc.) and an active ingredient (organic polysiloxane), and may also contain other additives to improve performance.
2.Main functions and features
Improve flowability:
Silicone masterbatch can enhance the flowability of thermoplastic resin in a molten state, thereby reducing energy consumption in extrusion injection molding and improving production efficiency.
Promote dispersion:
Helps improve the dispersion of fillers, making the internal structure of plastic products more uniform.
Desempenho da superfície:
Improve the surface smoothness of the final plastic product, reduce the surface friction coefficient, and improve wear and scratch resistance.
Low dosage and high efficiency:
A small dosage (usually 5%) can achieve significant modification effects without much consideration of its reaction with the matrix material.
3.Application Fields
Silicone masterbatch is widely used in the processing of various thermoplastic materials, such as PP, PE, ABS, PA, etc. It can be used to make various plastic products, such as pipes, sheets, films, injection molded parts, etc., to enhance the overall performance of the product.
Silicone masterbatch can significantly improve the wear resistance of shoe soles through its unique chemical and physical properties.
The following are the main mechanisms by which silicone masterbatch improves the wear resistance of shoe soles:
Lubrication mechanism:
The silicone monomer in the silicone masterbatch can form chemical bonds with the substrate, which can increase the lubricity of the material and reduce the friction between the sole and the ground during walking or movement. The improvement of lubricity helps to reduce wear and prolong the service life of the sole.
Filling mechanism:
The filler in silicone masterbatch can be filled into the sole material to form a high hardness particle network. These particles can reduce the contact area and decrease the wear rate during the friction process. Meanwhile, the chemical reaction between the filler and the substrate also helps to improve wear resistance, making the sole more sturdy and durable.
Surface hardening:
Organic silicon monomers in silicone masterbatch can also form oxide compounds with the substrate, forming an oxide film on the surface of the shoe sole. This oxide film can increase the hardness of the sole surface, making it more wear-resistant. Experimental results have shown that the wear amount of shoe sole materials with added silicone masterbatch is significantly reduced in simulated wear experiments.
Comprehensive performance improvement:
In addition to wear resistance, silicone masterbatch can also improve other properties of shoe soles, such as improving demolding, reducing scrap rate, and increasing brightness. These comprehensive performance improvements also contribute to improving the durability and service life of the shoe sole.
In practical applications, silicone masterbatch is widely used as a wear-resistant modifier in various shoe materials, such as TPR, EVA, TPU, and rubber outsole. By adding an appropriate amount of silicone masterbatch, the wear resistance of the sole can be greatly improved, the service life of the shoe can be extended, and the comfort and practicality of the sole can be maintained.
Xiangxi silicone masterbatch has been used a lot as anti-abrasion additive for shoe soles/slippers.
