Polyurethane Insulation Rigid Foam information
Key Characteristics:
- Thermal Insulation Expertise: The closed-cell rigid foam brings forth outstanding thermal insulation properties, making it an ideal choice for applications in refrigerators, freezers, and even water heaters.
- User-Friendly Flexibility: This foam material is surprisingly easy to work with. You can even pinch it with your hand force, showcasing its pliability.
- Crafting and Bonding: From model-making to bonding benzene boards and sculptures, the closed-cell rigid foam’s versatility is evident. It’s perfect for various creative projects.
- Steady Performance: With a solid bonding capacity with materials like cement, wood, metal, glass, and plastic, it seamlessly fits into various building and construction projects.
- Water-Resistant Floatation: Its closed-cell structure ensures it doesn’t absorb water and can even float on the water surface.
- Room for Expansion: The foam can expand to an impressive 15 to 20 times its original volume when exposed to air.
- Easy Mixing and Molding: Mix the two materials in a 1:1 weight ratio, watch them blend, and then pour into your desired container for gradual foam molding.
- Quantity and Expansion: When a kilogram of combined material foams, it can expand up to about 15 liters.
- Temperature Influence: Temperature has a significant impact on foam stability, expansion time, and curing. Lower temperatures result in a slower expansion and smaller volume.
- Challenges in Storage: The B material might show inflation in high temperatures or when shaken. If stored for long periods, proper shaking is essential to avoid uneven foaming.
Usage Guide:
- Mix the two materials in a 1:1 weight ratio until well-blended.
- Pour the mixture into your intended container for gradual foam molding.
- The material expands around 15 to 20 times its original volume.
- Foam molding takes about 3 minutes at 20°C, and it hardens in around 10 minutes.
- Note that temperature affects foaming volume and timing.
Tips for Best Results:
- In hotter temperatures, the B material might inflate. Cooling it down and gently releasing pressure will help.
- Be cautious with B material exposure to air; it can clump. After use, seal it properly.
- If there’s layering due to storage, shake the white material well before use.
- For coloring, you can add color paste or opt for post-foaming painting or acrylic coloring.
- If foam sticks to the mold, applying a mold surface release agent can help with demolding.
