Polyol for adhesive - Application
Open Data Unverified Data
Polyols are important components widely used in adhesives and coatings, and bio based polyols refer to polyols produced from renewable biomaterials such as vegetable oils, starch, or other biomass. Compared to traditional petroleum based polyols, bio based polyols have many advantages, such as lower carbon footprint, better biodegradability, and sustainability.
Characteristics of bio based polyols
1. Reproducibility: Biobased polyols are derived from renewable resources, reducing dependence on fossil fuels.
2. Environmentally friendly: The emissions during production and use are usually low, so the impact on the environment is relatively small.
3. Superior performance: Some bio based polyols can provide excellent adhesion and water resistance, meeting the needs of high-performance adhesives.
4. Diversity: There are a wide variety of bio based polyols that can be selected and formulated according to different needs, making them suitable for various applications.
application area
The application of bio based polyols in adhesives mainly includes:
1. Building materials: used for bonding materials such as wood, flooring, and walls, providing good adhesion and durability.
2. Packaging materials: Provide effective sealing and bonding functions in paper and plastic packaging.
3. Automotive industry: used for bonding vehicle components, enhancing structural strength and durability.
4. Electronic products: Used for bonding and packaging in electronic components, providing protection and insulation functions.
Polyols used in adhesives are an important polymer raw material, mainly used for the synthesis of polyurethane, epoxy resin, and other types of adhesives. Polyols can provide structure and performance, making the final product have good adhesion, flexibility, and durability.
Types of polyols
According to their molecular structure and characteristics, polyols used in adhesives can usually be classified into the following categories:
1. Polyether polyols:
-Usually polymerized from epoxides such as propylene oxide or ethylene oxide.
-Has good flexibility and water resistance, suitable for various applications.
2. Polyester polyols:
-Synthesized by reacting polyols with polyacids.
-Usually possessing excellent mechanical properties and hydrolytic stability, it is suitable for use in high-performance adhesives.
3. Biobased polyols:
-Made from vegetable oil, starch, or other biomass sources.
-Providing renewable sources and environmentally friendly features is gradually gaining popularity in the market.
Application in adhesives
1. Polyurethane adhesive:
-Formed through the reaction of polyols and isocyanates, it is widely used in fields such as construction, automotive, and shoe materials.
2. Epoxy adhesive:
-Made by the reaction of polyols and epoxy resin, it has excellent adhesion and chemical resistance, and is suitable for materials such as metals, glass, ceramics, etc.
3. Water based adhesive:
-Using polyols as the main component in the aqueous phase is environmentally friendly and meets increasingly strict emission standards.
Factors influencing the selection of polyols
When choosing polyols for adhesives, the following factors should be considered:
-Chemical compatibility: Compatibility with the chemical properties of other raw materials.
-Mechanical properties: required adhesive strength, flexibility, and durability.
-Environmental impact: Whether it meets the requirements of environmental protection and sustainable development.
-Processability: Operational characteristics in production and application, such as fluidity and curing time.
summary
Polyols are key components in adhesive formulations, and selecting appropriate polyols can significantly improve the performance of adhesives. With the advancement of technology, more and more types of polyols have emerged in the market, especially bio based polyols, which meet the dual needs of environmental protection and performance.
