What techniques prevent yellowing in clear polyethylene sculptures over time?

Clear polyethylene sculptures are prized for their transparency and durability, but yellowing over time can diminish their aesthetic appeal. To prevent this, several techniques can be employed. First, UV stabilizers or coatings can shield the polymer from sunlight, which is a primary cause of degradation. Incorporating antioxidants during manufacturing helps neutralize free radicals that accelerate yellowing. Additionally, using high-quality, virgin polyethylene resin reduces impurities that contribute to discoloration. Proper storage away from direct sunlight and extreme temperatures also prolongs clarity. For long-term preservation, applying a protective sealant or wax can further safeguard the sculpture. By combining these methods, artists and collectors can maintain the pristine appearance of clear polyethylene sculptures for years.
