Expancel 950 DU 80 is a grade of Expancel® microspheres, which are dry, unexpanded microspheres used as lightweight fillers in various applications. These microspheres are made of a thermoplastic shell encapsulating a gas. When heated, the gas inside expands, causing the microsphere to increase in volume dramatically while maintaining its shape.
Key Characteristics of Expancel 950 DU 80:
- Particle Size (D(0.5)): 18–24 µm
- Thermomechanical Analysis:
- Tstart (Start of Expansion): 136–146 °C
- Tmax (Maximum Expansion): 188–200 °C
- Solvent Resistance: Rated 5 (no unfavorable effects expected)
- Density: ≤ 12 kg/m³
Uses and Applications:
Expancel microspheres are used to reduce weight, improve insulation properties, and modify surface characteristics in various products, including:
- Paints and coatings
- Sealants and adhesives
- Plastics and rubber
- Printing inks
- Textiles
Benefits:
- Lightweight Filler: Reduces the density of end products.
- Thermal Insulation: Provides good thermal insulation properties.
- Dimensional Stability: Maintains shape and volume under varying conditions.
- Chemical Resistance: High resistance to solvents and chemicals.
Handling and Storage:
- Shelf Life: Use within three years from the production date if unopened.
- Storage: Store in a cool, dry place in original packaging to maintain quality and performance.
Additional Information:
- The microspheres are resistant to most solvents, rated 5 for chemical resistance, indicating no unfavorable effects are expected.
- Typical applications and performance characteristics can vary, and it is recommended to test the product for specific uses to ensure suitability.
Expancel 950 DU 80 provides significant advantages in reducing weight and enhancing properties such as thermal insulation and chemical resistance in various applications, making it a versatile additive in manufacturing and production processes.
