Are polyethylene sculptures prone to expansion in humid conditions?
Polyethylene sculptures are generally resistant to moisture absorption, making them less prone to expansion in humid conditions compared to other materials. However, prolonged exposure to high humidity can cause minimal dimensional changes due to the material's slight porosity. Manufacturers often treat polyethylene with UV stabilizers and coatings to enhance its durability. For outdoor installations, proper maintenance and ventilation can mitigate any potential effects of humidity. Overall, polyethylene remains a stable choice for sculptures in varying climates.
