Durability under prolonged stress is another area where neoprene shows limitations. In applications requiring continuous flexing or stretching, such as in joint areas of protective suits, neoprene may exhibit fatigue and develop cracks over time. This wear and tear can compromise the integrity of the protective gear, reducing its effectiveness and lifespan.

Neoprene's performance in extreme pressure conditions also presents challenges. While it offers good compression resistance, it may not provide sufficient protection in high-pressure environments, limiting its use in deep-sea diving suits or certain aerospace applications without additional reinforcement.

The material's breathability is another limitation, particularly in hot and humid conditions. Neoprene's closed-cell structure, while excellent for insulation, can lead to heat and moisture buildup inside protective gear. This can cause discomfort and potentially dangerous overheating for the wearer during prolonged use or intense physical activity.

Electromagnetic shielding is an area where standard neoprene falls short. In environments with high electromagnetic interference or radiation, neoprene alone does not provide adequate protection, necessitating additional layers or treatments to enhance its shielding capabilities.

Lastly, the environmental impact of neoprene production and disposal is a growing concern. The manufacturing process involves potentially harmful chemicals, and the material's slow degradation rate poses challenges for sustainable disposal. This limitation is becoming increasingly significant as industries strive for more environmentally friendly solutions in protective gear.

Addressing these limitations is crucial for expanding neoprene's applicability in extreme conditions and improving the safety and comfort of users relying on neoprene-based protective gear. Future research and development efforts must focus on enhancing these aspects to unlock the full potential of neoprene in challenging environments.
