Polyurethane is a versatile plastic material that has revolutionized various industries with its adaptability and performance. Piedmont Plastics stocks polyurethane sheet, tube, and rod, and in a variety of configurations. This includes formulations covering an extremely wide range of stiffness, hardness, and densities, which consist of low-density flexible and rigid foams, soft elastomers, and hard solid plastics.

The unique characteristics of polyurethane, such as its tear and abrasion resistance, excellent load-bearing capacities, and outstanding flexibility, make it a go-to material for both industrial and consumer needs. Polyurethane also competes well with traditional steel, aluminum, ceramic, and rubber parts.

Advantages of Polyurethane

Polyurethane stands out as a remarkable material, blending the flexibility of traditional rubber with the resilience and strength of traditional metals. Its wide hardness spectrum also empowers engineers to replace conventional materials with something that excels in performance and boasts superior physical properties.

Here are some other key benefits of polyurethane:

Superior Durability: Polyurethane is known for its exceptional tear and abrasion resistance, ensuring longevity and consistent performance under various conditions.
Strength and Compression Resistance: It boasts strength that can surpass rubber by up to five times, and its ability to withstand compression without deformation is a significant advantage in numerous applications.
Load Bearing and Flex Fatigue Resistance: With an impressive load-bearing capacity and resistance to flex fatigue, polyurethane is suitable for heavy-duty applications.
Adhesive Compatibility: Polyurethane’s excellent substrate adhesive abilities make it ideal for applications requiring strong bonding with other materials.
Cost-Effectiveness: Compared to traditional materials, molding, polyurethane production is more cost-effective, especially for small production runs.
Versatility in Fabrication: Polyurethane can be easily fabricated, machined, and thermoformed, providing flexibility in design and application.
Compliance with Standards: Polyurethane materials can meet various compliance standards, including UL, FDA, and RoHS, ensuring safety and quality in diverse industries.

Common Applications of Polyurethane

Polyurethane plastic sheets are highly versatile and find applications across various industries due to their unique properties such as durability, flexibility, and resistance to abrasion, chemicals, and impact. Here are some of the common applications:
