Polyurethane Shell Black & White Components

Updated: 2026-07-21

Overview

Polyurethane Insulation Shell Black and White Material is a two-component chemical system comprising polyol (white material) and isocyanate (black material). When mixed, these components react to form rigid polyurethane foam, widely used for thermal insulation in industrial and construction applications. The system is favored for its excellent insulation properties, mechanical strength, and durability. It is commonly applied to insulate pipes, tanks, and other equipment requiring temperature stability. The material is also lightweight and resistant to moisture, making it suitable for harsh environments.

Physical and Chemical Properties

The polyurethane foam formed from this system exhibits low thermal conductivity (typically 0.020-0.025 W/m·K), ensuring efficient insulation. The foam density ranges from 30-50 kg/m³, providing a balance between strength and weight. The material is chemically stable, resistant to water, and adheres well to various substrates. It is also flame-retardant when formulated with additives. The two components must be stored separately and mixed in precise ratios to achieve optimal performance.

Main Applications

This material is extensively used in industrial insulation, particularly for pipes and storage tanks in oil, gas, and chemical plants. Its thermal efficiency helps reduce energy loss and maintain process temperatures. In construction, it is applied to insulate walls, roofs, and cold storage facilities. The material's versatility also extends to HVAC systems and refrigeration units, where consistent thermal performance is critical.

Safety and Storage

Proper handling is essential due to the reactive nature of the components. Isocyanate (black material) can cause skin and respiratory irritation, requiring PPE such as gloves, goggles, and masks. Storage conditions must prevent moisture ingress and exposure to extreme temperatures. Containers should be tightly sealed and kept in well-ventilated areas. Shelf life is typically 6-12 months, depending on storage practices.

B2B Procurement Guide

When procuring this material, prioritize suppliers with ISO or other relevant certifications. Request technical datasheets to verify properties like thermal conductivity and density. Testing small batches before large-scale purchase is advisable to ensure compatibility with your application. Bulk orders may qualify for discounts, but confirm lead times and storage requirements to avoid material degradation.
