3. Flexibility (Low)
Low flexibility is a defining characteristic of acrylic nails created with methyl methacrylate (MMA). This reduced flexibility is a direct consequence of the rigid polymer structure formed by MMA monomers. While this rigidity contributes to the high durability and resistance to wear often associated with MMA acrylics, it also presents several potential drawbacks and safety concerns. The inflexible nature of MMA nails makes them less able to absorb shock and stress compared to more flexible alternatives like EMA (ethyl methacrylate). This lack of flexibility increases the likelihood of the artificial nail cracking or shattering upon impact, potentially causing damage to the underlying natural nail.
For example, a sudden impact, such as striking a hard surface, can cause an MMA nail to break, potentially leading to a painful nail avulsiona separation of the nail plate from the nail bed. The strong adhesion characteristic of MMA further exacerbates this risk. Because MMA adheres strongly to the natural nail, the force of the impact is transmitted directly to the nail plate, increasing the probability of damage. In contrast, more flexible nail enhancements can bend and absorb some of the impact force, reducing the risk of such injuries. This difference in flexibility has significant practical implications for individuals considering nail enhancements. Those engaged in activities involving manual labor or frequent hand use should carefully weigh the trade-off between durability and flexibility.
The low flexibility of MMA acrylics represents a key factor influencing both their durability and potential safety risks.
