It can be modified with additives
Corrugated plastic is a versatile material with a wide range of applications, from signage and packaging to construction and hobbies. Its lightweight, durable, and cost-effective nature makes it a popular choice for many industries. The plastic is typically made from polypropylene, a thermoplastic that is known for its rigidity and impact resistance.
The properties of corrugated plastic can be enhanced through the addition of additives. These additives are melt-blended into the plastic sheets to meet specific requirements. One of the key benefits of using additives is to improve the plastic's resistance to ultraviolet (UV) radiation. UV stabilizers are added to protect the sheets from sun damage, ensuring that the material can withstand prolonged exposure to sunlight without degradation. This is particularly important for outdoor applications, such as signage, where corrugated plastic is exposed to the elements.
