Adhesive vs. Gum — What's the Difference?

By Urooj Arif & Maham Liaqat — Updated on May 9, 2024
Adhesive is a binding agent used to adhere objects together, designed for durability and strength, while gum primarily refers to substances that are chewable and malleable, often used for recreational chewing or as a less strong, natural adhesive.

Key Differences

Adhesive is formulated to create a strong, permanent, or semi-permanent bond between different materials, such as metal, wood, or plastic. It includes varieties like epoxies, glues, and cements that are crucial in construction and manufacturing. Gum, on the other hand, usually refers to natural or synthetic substances that are chewable and used primarily for enjoyment, like chewing gum, or derived from natural sources like gum arabic, which serves as a mild adhesive in culinary and artistic applications.
Adhesives are chosen based on the required strength, flexibility, and environmental resistance of the bond they need to form. Industrial adhesives can withstand extreme conditions, such as high temperatures and moisture. Gum, whereas, is selected based on its texture and flavor when used for chewing, and its binding ability in less demanding adhesive roles, like sealing envelopes or applying labels.
The application process for adhesives varies from simple household glue sticks to complex industrial adhesive applications requiring precise mixing and curing conditions. Gum, on the other hand, is generally used directly in its natural state or after minimal preparation, like softening or melting.
Adhesives often contain chemicals that can be hazardous, requiring careful handling, proper ventilation, and sometimes protective equipment. Gum is typically non-toxic and safe for consumption or regular handling, making it more user-friendly in everyday situations.
While adhesives are an essential component in various industries, including automotive, aerospace, and electronics, providing structural integrity, gum is widely used in food and art, emphasizing its versatile but less structural nature.

Adhesive

Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation.The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding.
