What is the difference between electronic yellow gum and electronic silica gel and silica gel glue?

Electronic cement is a kind of one-component, sticky glue, glue because of its color is yellow, so the industry has always been just call it UL glue or UL yellow glue, UL flame retardant cement, cement, electronic cement, such as name, can be divided into flame retardant cement and generic electronic cement, belonging to the solvent evaporation type glue, glue relay strong and good toughness.

Electronic silica gel is also a kind of single component, viscous or paste type glue, the role of glue is fixed, bonding, insulation, sealing, filling, seismic, waterproof, reinforcement and other functions.It is a kind of glue widely used in the electronic industry.

Electronic yellow glue and electronic silica gel are widely used in the production and processing of electronic and electrical products.So what are the differences between electronic silica gel and electronic yellow glue? Can they be used instead of each other?Yao can engineer to do the related analysis, to talk about the related problems between electronic silica gel and electronic yellow glue.

1. Scope of use.The use range of electronic yellow gum and electronic silica gel is very common, are used in the field of electronic and electrical products.But the use of electronic silica gel is more extensive and broad.Electronic silica gel not only has the function of bonding, insulation, but also plays the role of sealing and filling, and the volume of glue will not change.The volume of electronic yellow glue will decrease during the curing process.

2, adhesive relay.Under the same circumstances, the adhesion of electronic yellow glue relay is stronger.Especially for the adhesion of some metals and plastics, the adhesion of electronic yellow glue is better.But if the adhesion requirements are not too high, the electronic silica gel adhesion is also very good, and the temperature and aging resistance is also superior, the use is also more convenient, can cooperate with automatic mechanical sizing.

3. Glue smell.The smell of electronic silica gel is smaller than that of electronic yellow glue, because there is no solvent in the constituent materials of electronic silica gel, and there is a solvent in the constituent materials of electronic yellow glue.The smell of glue is mainly determined by the smell of the solvent.

4. Other parameters.The temperature and weather resistance of electronic silica gel is better than that of electronic yellow glue.The temperature resistance of electronic silica gel is generally between -50 degrees to 250 degrees, and the temperature resistance of electronic yellow glue is generally between -45 degrees to 130 degrees.Electronic silica gel and electronic yellow glue generally have flame retardant type of glue.

5, heat conduction and heat dissipation.Electronic silica gel has heat conduction and heat dissipation type of silica gel products.The heat conduction and heat dissipation effect of electronic yellow glue is worse.Generally, products and electronic components requiring heat conduction and heat dissipation need to use radiant heat conduction silica gel and heat dissipation silica gel glue.

More electronic silica gel, radiating silica gel, silica gel glue, electronic yellow glue and other product information and related glue bonding, the use of technology and other issues can be contacted with Shenzhen Yaoneng Technology, can provide customers with product sample, bonding program, technical exchange and other all-round services.
