Silicone Modified Polyurethane

Updated: 2026-07-19

Overview

Silicon PU is a specialized polyurethane material enhanced with silicone components, offering superior elasticity, durability, and resistance to environmental factors. It is widely used in sports surfaces, industrial coatings, and flooring due to its ability to withstand heavy use and harsh weather conditions. The material combines the flexibility of polyurethane with the weather resistance of silicone, making it ideal for outdoor applications. Its versatility and performance have made it a preferred choice in construction and sports industries.

Physical and Chemical Properties

Silicon PU exhibits high elasticity and tensile strength, allowing it to absorb impact and return to its original shape. It is resistant to UV rays, temperature fluctuations, and chemical exposure, ensuring long-term durability. The material is typically insoluble in water but can be dissolved in certain organic solvents. Its density ranges from 1.1 to 1.2 g/cm³, and it maintains stability under a wide range of environmental conditions.

Main Applications

Silicon PU is primarily used in sports surfaces, such as running tracks, tennis courts, and playgrounds, due to its shock-absorbing properties and slip resistance. It is also employed in industrial flooring and coatings for its abrasion resistance. Additionally, the material is used in adhesives and sealants, where its flexibility and durability are advantageous. Its weather resistance makes it suitable for outdoor applications in construction and infrastructure projects.

Safety and Storage

B2B Procurement Guide

When procuring Silicon PU, verify the material's specifications, including elasticity, UV resistance, and durability. Ensure the supplier provides certifications and batch consistency reports to guarantee quality. Compare prices from multiple suppliers, keeping in mind that higher-grade materials may cost more but offer better performance. Consider the application requirements and environmental conditions to select the most suitable product. Bulk purchases may offer cost savings, but ensure proper storage conditions to maintain material integrity.
