What are long-chain polymers characterized by compared to short-chain polymers?

Long-chain polymers are characterized by their structural configuration, which leads to enhanced strength and durability compared to short-chain polymers. They tend to create more stable and tougher bonds, which can result in better performance in various applications. However, they are often less likely to cause irritation since they have a greater molecular weight and are usually formulated to be gentler on the skin. This gentler nature makes them preferable for applications such as eyelash extensions, where sensitivity is a significant concern.

In contrast, short-chain polymers typically have lighter, less stable structures which can lead to weaker performance in certain aspects and may result in increased irritation. They also may have quicker curing times and can release more fumes, making them less suitable in environments requiring lower irritant levels. Thus, the characteristics of long-chain polymers as low irritants and relatively gentler options are why this option is indicative of their properties in comparison to short-chain polymers.
