Thermoplastic Adhesive Formulation
$ 75
Description
Thermoplastic adhesive formulation such as hot melts containing traditional ingredients such as acid or acid-derived grafted polyolefins are substantially improved by the incorporation of acrylic acid grafted polypropylene, polyethylene and/or ethylene-propylene polymer materials. . Alternatively, novel adhesive compositions are developed in which the polyolefin component is a fully grafted polyolefin.
Hot melt adhesives are particularly useful because they have very fast setup or bonding times. Strong bonds form when the adhesive cools below its melting point and crystallizes. Solvents or water vapors or chemical cures do not require long waiting times as with other types of adhesives. Depending on the composition, hot melt adhesives can be produced with good tack, high bond strength, good flexibility, low temperature properties, and good environmental resistance.
Key characteristics of thermoplastic adhesives formulation
- Meltable and Reversible:
- They can be melted or softened when heated and solidify upon cooling, allowing for multiple cycles of application and reapplication.
- Application Methods:
- Thermoplastic adhesives are typically applied in a molten state. Common application methods include hot melt extrusion, hot melt spraying, or using hot melt glue guns.
- Rapid Setting:
- They usually have a fast setting time, providing quick bonding once they cool and solidify.
- No Chemical Crosslinking:
- Unlike thermosetting adhesives, thermoplastics do not undergo chemical crosslinking during curing. Their bonding relies on physical changes in state.
- Versatility:
- Thermoplastic adhesives are versatile and find applications in various industries, including packaging, automotive, textiles, and electronics.
- Wide Range of Materials:
- They can bond a wide range of materials, including plastics, metals, fabrics, and more.
- Bond Strength:
- The bond strength of thermoplastic adhesives can vary based on the specific formulation and the materials being bonded.
