Common adhesive types are diverse and categorized primarily by their chemical composition, application, and physical form. Here's an elaborate classification, utilizing advanced grammar, vocabulary, and punctuation:

By Chemical Composition

1. Silicone-Based Adhesives
   • Characteristics: Possess cold and heat resistance, weather ability, waterproofness, moisture resistance, high fatigue strength under strain, minimal permanent deformation, and non-toxicity.
   • Applications: Rapidly growing in domestic markets, primarily used for sealing and bonding in construction, automotive, and electronic industries.
2. Polyurethane Adhesives
   • Characteristics: Capable of bonding a wide range of materials and maintaining material properties at low or ultra-low temperatures.
   • Applications: Extensively used in footwear manufacturing, packaging, automotive, and magnetic recording materials.
3. Polyacrylic Adhesives
   • Characteristics: Primarily used in the production of pressure-sensitive adhesives (PSAs) with certain versatility.
   • Applications: Widespread in textiles, construction, and packaging industries.
4. Epoxy Adhesives
   • Characteristics: Offer strong bonding between metals and most non-metals, with high cured strength and hardness.
   • Applications: Extensively utilized in construction, automotive, electronics, appliances, and everyday household items.
5. Urea-Formaldehyde Adhesives
   • Characteristics: Primarily used in wood processing but may release formaldehyde levels above international standards.
   • Applications: Manufacture of medium-density fiberboard (MDF), plasterboard, plywood, and particleboard.
6. Synthetic Adhesives
   • Characteristics: A vast array with varying properties tailored to specific needs.
   • Applications: Widely applied in wood processing, construction, decoration, automotive, footwear, packaging, textiles, electronics, print binding, and more.

By Application

1. Industrial Adhesives
   • Including electrical adhesives, structural adhesives, anaerobic structural adhesives, and silicone RTV sealants, primarily used in industrial assembly and equipment maintenance.
2. Electronic and Electrical Adhesives
   • Such as silicone rubber, electronic sealants, and transparent electronic sealants, primarily used for bonding, sealing, and potting of electronic components.
3. Photovoltaic Adhesives
   • Including PV module bonding and sealing adhesives, and silicone potting compounds, primarily used for bonding, sealing, and potting in photovoltaic modules.
4. Wind Energy Adhesives
   • Including silicone RTV sealants and mold-closing adhesives, primarily used for sealing and structural bonding in wind turbine blades.
5. Automotive Adhesives
   • Including hemming adhesives and vibration-damping adhesives, primarily used in automotive manufacturing and maintenance.
6. Construction Adhesives
   • Including ceramic tile adhesives and stone adhesives, primarily used for decoration, sealing, and structural bonding in construction projects.

By Physical Form

1. Hot-Melt Adhesives
   • Based on raw materials like EVA or polyamide, melted for rapid bonding of various materials.
2. Sealants
   • Used primarily in door, window, and prefabricated housing assembly joints, with premium sealants like silicone and polyurethane offering exceptional sealing performance.
3. Liquid Adhesives
   • Such as acrylic or polysulfide liquid sealants, used for sealing static and dynamic joints.
4. Others
   • Including pressure-sensitive adhesives (PSAs) and anaerobic adhesives, featuring unique bonding and curing characteristics.

In summary, the myriad of common adhesive types, each with its unique chemical composition, application, and physical form, necessitates careful consideration of specific application scenarios and requirements when selecting an adhesive.
