The Best Plastic Materials for Outdoor Product Application

Plastic is increasingly gaining popularity for outdoor use due to its unmatched functionality and versatility that alternative building materials cannot match, especially in the context of outdoor applications. Let’s explore why plastic has become the preferred choice for outdoor use by examining the limitations of other materials.

In the past, wood was commonly used for outdoor applications, including furniture and playground equipment. However, even with proper chemical treatments, wood is not ideal for prolonged outdoor use. It is susceptible to rotting, warping, and splintering, which can pose safety risks. Additionally, wood has limited shaping possibilities and is typically restricted to rigid, angular arrangements. Glass, on the other hand, has been widely used for its ability to transmit light, making it popular for structures like greenhouses. However, glass is extremely fragile and can easily crack or shatter even with minor impacts. Its fragility, combined with its weight, increases the risk of injury and makes it less suitable for outdoor use.

In contrast, plastic emerges as the superior choice for outdoor applications. It offers numerous advantages over other materials. Plastic can withstand severe weather conditions, including snow, while remaining durable, watertight, and fade-resistant. Many types of plastic also possess excellent resistance to UV light, ensuring that outdoor plastics retain their color and structural integrity over time. When selecting plastic for outdoor applications, it is important to consider the specific requirements of your installation.
