Rigid Polyurethane (PUR) Insulation Material

Product Overview

Rigid Polyurethane (PUR) is a closed-cell foam insulation material formed through precise formulation and chemical reaction of polyether/polyester and polyisocyanate. Its unique honeycomb structure delivers high closed-cell content (≥95%) and low water absorption, with cells containing low-conductivity blowing gas that effectively blocks heat transfer. As an efficient low-temperature insulation material, PUR maintains stable performance across a wide temperature range from -80°C to +100°C, making it an ideal choice for various cold insulation and low-temperature applications.

Key Features

• • Excellent Thermal Efficiency
    Thermal conductivity as low as 0.023 W/(m·K) provides superior insulation, significantly reducing energy consumption

  • Outstanding Mechanical Strength
    Compressive strength ≥200 kPa and tensile strength ≥200 kPa ensure structural integrity in demanding applications

  • Superior Moisture Resistance
    Closed-cell structure effectively prevents moisture penetration, with water absorption ≤5% by volume, maintaining stable performance

  • Easy Installation
    Lightweight and easy to cut, can be prefabricated into pipes, slabs, and other shapes to meet various installation requirements
