Easy Molding Solid Structure Rigid PU Foam Core Choice for FRP Sandwich Structures

Introduction

In the process of the coordinated development of polymer material and composite material technologies, polyurethane foam has become a key material in many fields due to its unique preparation process and adjustable performance advantages. As a polymer formed by mixing, reacting, and foaming two-component liquids (polyol and isocyanate) under the action of catalysts, foaming agents, etc., through high-pressure foaming equipment, polyurethane foam has derived three major categories—flexible foam, rigid foam, and semi-rigid foam—by virtue of differentiated structural design, accurately adapting to the functional needs of different scenarios. Among them, in the field of FRP composite materials, rigid polyurethane foam has become the core choice for sandwich structures due to its excellent mechanical properties and molding characteristics. Its innovative one-time composite molding process—PU raw materials are directly foamed and bonded between two FRP panels—can form a solid integral structure without bonding seams, which not only greatly improves the overall strength of the composite panel but also simplifies the production process, laying a solid foundation for the efficient application of FRP composite materials in the high-end manufacturing field.

Reasons for Choosing PU Foam Core Material

Value 1: Top-tier Thermal Insulation Efficiency

Ultra-low Thermal Conductivity for Temperature Retention: Its closed-cell structure and foaming gas yield an extremely low thermal conductivity, delivering thermal insulation performance over 1.5 times that of EPS.
Benefits for Customers:
- Significant Energy Savings: When applied in building envelopes or cold chain equipment, it drastically cuts cooling/heating energy consumption, directly reducing electricity costs with a short investment payback period.
- Compliance with High Standards: Easily meets the increasingly stringent global building energy efficiency regulations and environmental requirements.
- Stable Operational Environment: Provides a consistent internal climate for constant temperature and humidity workshops, cold storage facilities, etc., ensuring product quality.

Value 2: Excellent Strength-to-Weight Ratio

Rigid yet Lightweight: Offers outstanding compressive strength and flexural modulus at low density. When combined with FRP (fiberglass-reinforced plastic) panels, it creates a synergistic effect of "1+1>2".
Benefits for Customers:
- Lightweight with High Strength: The composite panels feature low overall weight while boasting high load-bearing capacity and wind resistance, reducing building structural loads and foundation costs.
- Durable and Long-lasting: The core material provides uniform support to the panels, preventing localized deformation and extending the service life of the boards.
- Easy Transportation and Installation: Light weight enables high installation efficiency, saving labor and construction schedule costs.
