The main uses can be roughly divided into silicone insulating paints, silicone coatings, silicone plastics and silicone adhesives.

Spherical resins and silicone resins are both resin-based materials, and their main differences are their chemical structures and application fields.

Spherical resins are microgranular materials composed of cross-linked polymers that are commonly used to immobilize enzymes, antibodies, cells, and other biomolecules. Spherical resins can have different chemical functional groups to adapt to the needs of various chemical reactions, such as carboxyl, amino, thiol, etc. They are usually prepared by cross-linking polymerization, and their pore size and adsorption capacity can be adjusted by controlling the degree of cross-linking.

Silicone resin is a polymer material containing silicon bonds, and Yusheng usually has the characteristics of high heat resistance, high mechanical strength, chemical resistance and excellent insulation properties. Silicone resins can be divided into two types: linear silicone polymers and cross-linked silicone polymers, where cross-linked silicone polymers are usually prepared by the addition reaction of siloxanes. Silicone resins are widely used in construction, electronics, automobiles, aviation and other fields.

In summary, the difference between spherical dendritic lipid and silicone resin is mainly due to the chemical structure and application field.

Spherical resins and silicone resins are two different types of chemical materials.

Spherical resin, also known as polymer microspheres, is a small particle made from polymers. They are available in many applications, such as microsphere-based pharmaceutical, cosmetic, and other personal care products. Spherical resins can be prepared with controlled diameter and dispersion and are highly homogeneous, stable and reproducible.

Silicone resin, on the other hand, is a polymeric material that contains organic groups and silicon atoms (Si). These materials are often used in the manufacture of seals, coatings, glues, electronic devices, and other fields due to their excellent heat resistance, chemical resistance, insulating properties, and rubber elasticity.

Overall, there are obvious differences between the two materials in terms of composition, properties, and application fields.

<> silicone-free resin is mainly used as a building decoration binder or thickener, and can also be used for the coating of materials such as glass fiber sleeve and silicone tube, as well as the insulation and moisture-proof adhesive of circuit boards. Resin usually refers to the softening of the spine after heating, and there is a tendency to flow and bury indiscriminately under the action of external force when softening, and it is solid, semi-solid, and sometimes liquid organic polymer at room temperature. Broadly defined, any polymer compound that can be used as a raw material for the processing of plastic products.

There are two types of resins: natural resins and synthetic resins. Natural resin refers to the amorphous organic substances obtained from animal and plant secretions in nature, such as rosin, amber, shellac, etc. Synthetic resin refers to the resin product obtained by chemical synthesis of simple organic matter or chemical reaction of some natural products, such as phenolic resin, polyvinyl chloride resin and other bucket molds, of which synthetic resin is the main component of plastics.

Silicone is a synthetic polymer with silicon atoms and oxygen atoms as the main chains. Due to the silicon-oxygen structure that constitutes the backbone of the backbone, the swift molecules of organosilicon polymers are much more stable to heat and oxygen than ordinary organic polymers. Although the mechanical properties of silicones are not much different from other materials at room temperature, their physical and mechanical properties are excellent at high temperatures and low temperatures, and their properties are not affected by the alternating temperature of -60 to +250 times, so silicone polymers can be used in this temperature range for a long time.

Some silicone polymers are more effective at -100 levels. Due to the dipole effect in the organosilicon molecule, it can effectively buffer and weaken the influence of the external electric field, so as to protect the hydroxyl group attached to the silicon atom and make it not easy to be attacked by physical factors or chemical reagents. In addition to corrosion resistance, radiation resistance, high and low temperature resistance, the products made of polysilicone also have the characteristics of low moisture absorption, high insulation resistance, low dielectric constant, low stress, vibration reduction, environmental protection, low toxicity, flame retardant, and reworkable.

As a result, silicones are used in a wide variety of finished products such as adhesives, sealants, encapsulants, insulating coatings and silicone greases for a wide range of electronic devices.

Silicone resins have the following basic properties.

1.Good heat resistance and high temperature. Usually stable below 250.

2.There is very little reduction in electrical characteristics, and the high frequency varies very little with frequency.

3.It has excellent water resistance, and the arrangement of methyl groups in the molecule makes it hydrophobic, and the water absorption of its coating film is small. Even if it absorbs water, it is quickly released and returns to its original state.

Silicone resin is too heavy to use and needs to be understood in detail, and then silicone resin manufacturers will introduce the characteristics of silicone resin, and follow this article to learn about it.

The general-purpose silicone resin made according to the mature process and formula can meet most of the requirements of conventional use, but due to some inherent defects of the existing old silicone resin, it cannot fully adapt to the higher use requirements. In order to meet the demanding requirements of higher performance, there is an urgent need to improve the synthesis process and formula of old products, and at the same time, it is also necessary to research and develop new silicone resins with higher performance according to the development needs of contemporary new technologies.

Silicone resin is a synthetic compound that contains silicon and oxygen, as well as other organic groups. Among them, silicon plays a fundamental role in the performance of products. In a typical organic carbon compound, the backbone is carbon-linked; In silicone resins, on the other hand, the backbone is alternating silicon-oxygen atoms such as silicon-oxygen-silicon-oxygen.

This complex molecular structure makes silicone resins have particularly good resistance to high and low temperatures, wind erosion, oxidation and water resistance, good electrical and dielectric properties, outstanding arc and electrical breakdown resistance, and good heat conductivity, and silicone resins have been widely used.

Silicone resins retain excellent electrical insulation properties at 500°F, making them ideal materials for radomes and engines. Since silicone resins do not emit toxic gases at high temperatures, they are particularly suitable for missiles and aviation applications where high temperatures are required. One of the obvious drawbacks of this silicone resin is that the mechanical properties of silicone laminates are not as good as those of organic resin laminates at room temperature.

However, at 400 500°F, the mechanical strength of many organic resin layered materials has been significantly reduced, while silicone layered materials can work for a long time. Another disadvantage of silicone resins is that they cost more than phenolic resins.
