Introduction

Glue, a widely used adhesive, binds materials together through various means. Its composition can vary based on its intended use, involving organic, synthetic, or natural components. This article examines what glue is made of, its diverse types, and innovations by Dely Company.

Composition of Glue

Glue is primarily composed of polymers, which provide the necessary adhesive properties. These polymers can be natural, such as those derived from animals or plants, or synthetic, produced through industrial processes. Additives enhance performance, such as plasticizers enhancing flexibility and hardeners facilitating curing.

Types of Glue and Their Ingredients

Animal-Based Glues

Derived from collagen found in animal hides, bones, and tissues. Common ingredients include water, gelatin, and preservatives to prevent decomposition.

Plant-Based Glues

Typically derived from plant resins, such as starch, dextrin, or cellulose. These glues are often utilized in paper products and packaging.

Synthetic Glues

Produced from petrochemicals, these glues include cyanoacrylates (super glue), epoxies, and polyvinyl acetate (PVA). Their formulations involve complex chemical reactions to ensure quick setting and strong bonds.

Chemical Components of Glue

Various chemical compounds are integral to glue production:

• Epoxides: React with curing agents to form rigid, temperature-resistant bonds.
• Cyanoacrylates: Known for rapid polymerization when exposed to moisture, commonly used in household glues.
• Polyvinyl acetate: Utilized in water-based glues, it provides flexibility and is easily washable.

The presence of cross-linking agents and catalysts is vital, as they influence setting time and bond strength, measured in megapascals (MPa).

Dely Company Solutions

Dely Company has pioneered eco-friendly adhesives by integrating biodegradable components into their formulations. This includes:

• Bio-based polylactic acid (PLA) adhesives for reduced environmental impact.
• Innovative water-soluble glues with enhanced biodegradability.
• Revolutionary gluten-based adhesives for applications in sustainable packaging solutions.

Dely's innovations cater to industrial demands, ensuring products maintain adhesive strength while reducing carbon footprint and reliance on petrochemicals. Their solutions meet ISO environmental standards, boasting a reduction in volatile organic compounds (VOCs) by up to 80%.

Conclusion

The formulation of glue is a testament to the adaptability of chemical sciences in creating versatile materials from diverse origins. As exemplified by Dely Company’s solutions, the future of adhesives lies in sustainable practices that align with global environmental goals.
