Polydimethylsiloxane (PDMS) is a siloxane polymer with high chemical stability, which is difficult to remove by conventional cleaning. It is necessary to select targeted cleaning agents based on its hydrophobicity and chemical inertness, while strictly avoiding damage to the chip (silicon substrate, metal wiring, coating, etc.). Specific suggestions are as follows:

Both dimethyl silicone oil and vinyl silicone oil can be used as auxiliary materials (e.g., lubricants, plasticizers, damping regulators) in rubber shock absorbers. However, the two differ significantly in their applicable scenarios and performance. The selection should be based on the core requirements of the shock absorber (such as operating temperature, rubber material, damping stability, and service life). There is no absolute "better" option—only "more suitable" ones.

In the performance of amino silicone oil, the relationship between amine value and hand feel stiffness is not a simple linear correlation, but follows the rule of an "optimal range": Within a certain range, an increase in amine value can improve the hand feel; however, when the amine value is too high, the hand feel does tend to become stiffer, and the silkiness may also decrease. The specific principles are as follows:

Dimethyl silicone oil (with a viscosity of 200 cSt) can be used on glass surfaces, and its applicability mainly depends on specific usage scenarios and needs. Here is an explanation from the aspects of characteristics, applicable scenarios, and precautions:

Absolutely, and in polyester fabric coating, amino silicone oil is often a better choice, especially for meeting adhesion, hand feel, and functional requirements. Here is a detailed analysis:

Dimethyl silicone oil can be used for polyester fabric coating, but appropriate parameters need to be selected based on specific application scenarios (such as functional requirements, coating processes, etc.). Below is a detailed analysis and recommendation:

Dimethyl silicone oil can be applied to PET films, and it is quite common in practical applications. Its functions mainly focus on improving the surface properties of PET films, as follows:

When using dimethyl silicone oil to improve the hydrophobicity of PP matrix, viscosity is a key parameter. Its selection needs to consider the hydrophobic effect, compatibility with PP, processing technology and final performance requirements. The following are specific suggestions and analyses:

Dimethyl silicone oil has a significant effect on improving the hydrophobicity of polypropylene (PP) matrix, but its specific performance depends on the addition method, dosage and process conditions. The following is a detailed analysis from the aspects of mechanism of action, effect performance, influencing factors and application precautions:
