Fischer PU 500 Premium Polyurethane Foam Beige 500 ml

The Fischer PU 500 Premium is a high-performance single-component polyurethane foam engineered for professional-grade assembly and insulation applications. This 500 ml canister delivers a reliable beige-colored foam that expands to fill voids, seal gaps, and provide thermal and acoustic insulation in various construction environments. Its formulation ensures strong adhesion to common building substrates, making it a versatile solution for both indoor and outdoor projects.

Advantages

This polyurethane foam stands out due to its excellent dimensional stability and high yield, which allows for efficient filling of joints and cavities. The material offers superior resistance to aging and moisture, ensuring long-term durability of the sealed areas. Its professional-grade consistency provides a uniform structure, which is essential for maintaining consistent insulation properties across different surfaces. Furthermore, the foam is designed for easy application, enabling precise control during the installation process.

Suitable for

• Filling gaps between window frames and masonry
• Insulating wall penetrations and pipe ducts
• Sealing joints in partition walls
• General construction filling and insulation tasks

When it may not be suitable

This product is not intended for use on surfaces contaminated with oil, grease, or dust, as these will prevent proper adhesion. It is also not suitable for applications involving constant water immersion or direct contact with structural materials that require specific fire-rated certifications not met by this foam.

Key specifications

• Material: Polyurethane (PU)
• Color: Beige
• Volume: 500 ml
• Application type: Single-component foam

How to use

Before application, ensure the surfaces are clean, stable, and free of loose debris. It is recommended to slightly moisten the substrate to improve foam expansion and curing. Shake the canister vigorously for at least 20 seconds before attaching the applicator. Hold the canister upside down during use and fill the cavity to approximately one-third of its volume, as the foam will expand significantly. Allow the foam to cure fully before trimming any excess material.

What to consider before purchase

• Check the compatibility of the foam with the specific building materials being used
• Ensure the ambient temperature is within the manufacturer's recommended range for optimal curing
• Consider the expansion rate when calculating the amount of foam needed for large gaps

Usage recommendations

Always wear protective gloves and safety glasses during application. Ensure the work area is well-ventilated to prevent the inhalation of vapors. Store the canister in an upright position in a cool, dry place to maintain product shelf life.
