How does public interaction wear down polyethylene surfaces in tactile sculptures?
Polyethylene, a durable and versatile polymer, is commonly used in tactile sculptures due to its resilience and affordability. However, frequent public interaction—such as touching, rubbing, or pressing—can gradually degrade its surface. Over time, mechanical friction from repeated contact causes micro-abrasions, leading to visible wear, loss of texture, and even cracks. Environmental factors like UV exposure and temperature fluctuations can accelerate this process. Understanding these effects helps artists and conservators develop strategies to preserve tactile artworks while maintaining their interactive appeal.
