Polyethylene (PE) in its natural form has limited UV resistance; prolonged exposure to sunlight can degrade the material, reducing its mechanical strength and durability. However, UV stabilizers can be added during the manufacturing process to enhance its resistance to UV radiation. These stabilizers absorb or screen harmful UV light, significantly extending the outdoor lifespan of polyethylene products. It's common for outdoor applications, such as in agricultural films or outdoor furniture, to use UV-stabilized polyethylene to ensure longevity and performance under sunlight exposure. Nonetheless, the effectiveness of these stabilizers can vary, so it's important to consider the specific requirements of the application when selecting a polyethylene product for outdoor use.

Yarn Yoshi Amiibos, part of the amiibo line by Nintendo and characterized by their yarn-made exterior, are indeed unique in their make. However, being fabric-based, they require careful handling. Washing them like regular toys or figurines could cause damage to the electronic components inside and deteriorate the yarn. A safer alternative is spot cleaning with a damp cloth using mild detergent, followed by air drying. Avoid immersing them in water or using harsh chemicals. Always consult official care instructions or consider professional cleaning for expensive or collectible items to ensure longevity.

When comparing steel clips to polymer clips, the choice largely depends on the intended application. Steel clips are typically stronger and more durable, making them ideal for heavy-duty applications where high-strength retention is required. They can withstand greater stress and pressure without deforming or breaking, which is particularly beneficial in industrial settings. On the other hand, polymer clips offer several advantages over steel. They are generally lighter, less expensive, and easier to install, making them suitable for applications where cost and weight are significant factors. Polymer clips also provide good chemical resistance and insulation properties, which can be advantageous in certain environments. However, they may not perform as well under extreme temperatures or high loads. In conclusion, while steel clips excel in strength and durability, polymer clips offer benefits such as lower cost, lighter weight, and ease of installation. For most general-purpose applications, polymer clips might be sufficient, but for demanding situations requiring high strength, steel clips would be the better choice.
