Sealing and Waterproof Foam Product Introduction
Xiangyuan Polyurethane USF-WP Foam is a specially designed low-density waterproof polyurethane foam, created to offer an economical solution for sealing light, air, and moisture with excellent sealing performance. It also features good compressibility and resistance to deformation, making it suitable for irregular products. It only requires 50% compression to achieve efficient sealing and can be used in various environmental and temperature conditions. USF-WP Foam is free from plasticizers, minimizing the risk of damaging other materials it contacts. Additionally, it is an eco-friendly product with advantages such as low odor, low VOC, low misting, and halogen-free properties. It is available in different thicknesses to meet the performance requirements of various applications.

Sealing and Waterproof effect：
1.Cut the sample into a U-shape using a stamping tool.
2.Compress the sample to 50% of its original thickness and secure it with bolts and nuts. Pour water into the U-shaped sample placed between the acrylic plates (water pressure: 0.98 kPa, water height: 100 mm). Inspect whether there is any water leakage inside the sample or between the sample and the acrylic plates.
Sealing and Waterproof Foam Product Applications
This polyurethane foam waterproof sealing material, which can be used for various applications such as waterproofing, sealing, shock absorption, sound insulation, and cushioning, is suitable for specialized fields like automotive, electric motors, construction, and civil engineering. The material is soft and easily restores its original state, with a high compression ratio and excellent conformability. It provides minimal rebound force while maintaining stable waterproof performance. Durability and environmental friendliness are also among its key features.
