Which viscosity of dimethicone in improving the hydrophobicity of PP matrix

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:

How effective is dimethyl silicone oil in improving the hydrophobicity of PP matrix?

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:

What is the approximate amount of amino silicone oil to add when making solvent-free resins?

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:

What is an organosilicon linear body?

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.

When using amino silicone oil on aramid, are there any suggestions for the formula or steps?

The application of amino silicone oil on aramid fibers (such as Kevlar) is mainly to improve their surface properties (such as lubricity, softness, antistatic property, etc.) without damaging the core characteristics of aramid, such as high strength and high temperature resistance. The following are the formula design principles, typical process steps and precautions for aramid fiber treatment with amino silicone oil, for reference:

Is the difference in the viscosity of PDMS caused by the difference in the degree of polymerization?

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:
