Q
difference between polyurethane and polyvinyl chloride
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Polyurethane (PU) and Polyvinyl Chloride (PVC) are both polymers widely used in various applications, but they differ significantly in composition and properties. PU is known for its flexibility, durability, and resistance to abrasion and chemicals, making it ideal for high-wear applications like footwear, automotive parts, and some coatings. PVC, on the other hand, is a more rigid and cost-effective material commonly used in construction for pipes, cables, and siding due to its strength and resistance to moisture. While PVC can be made more flexible with additives, it generally lacks the breathable properties of PU. Additionally, PU is often preferred for applications requiring close contact with skin due to concerns over PVC's environmental and health impacts, linked to its chlorine content and the additives used to soften it. Choosing between PU and PVC depends on the specific requirements of the application, considering factors like flexibility, durability, and environmental impact.
