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:

The amount of amino silicone oil added in solvent-free resin systems is not fixed and mainly depends on the type of resin, target properties (such as smoothness, flexibility, surface tension adjustment), and the specific model of amino silicone oil (especially the amine value). The following is an analysis of reference ranges and influencing factors in common scenarios:

In the field of silicone materials, an organosilicon linear body (commonly referred to as a "linear silicone polymer" or "silicone linear body") refers to a silicone polymer with a linear chain structure. Its main chain consists of repeating silicon-oxygen bonds (-Si-O-Si-), with organic groups (such as methyl, ethyl, phenyl, etc.) attached to the silicon atoms. The molecular chain has no cross-linking or minimal branching, forming a straight-chain structure.

the viscosity difference of PDMS (polydimethylsiloxane, i.e., dimethyl silicone oil) is mainly caused by different degrees of polymerization, and it is also slightly affected by molecular structure (such as end group types). The detailed explanation from the perspective of chemical structure is as follows:

When selecting dimethyl silicone oil for curing into a film with hydrophobic and degassing properties, the viscosity should be chosen by comprehensively considering factors such as film uniformity, degassing efficiency, and film layer performance. The detailed analysis and recommended solutions are as follows:

Dimethyl silicone oil can, to a certain extent, address the issues of dry and dull surfaces of silica antiblock masterbatches. The following are the specific reasons:

When amino silicone oil is emulsified, the emulsion is stable, but after diluting with water, it becomes uneven, with flocs and the original oil precipitating. The following is an analysis of the specific causes and principles:
