FC422, part of the TPC Performance expandable polystyrene product range from Tabriz Petrochemical Company, is a high-performance EPS designed for a variety of applications where fast cycling and specific structural characteristics are required. This detailed guide explores the unique attributes, applications, and handling of FC422 to help manufacturers and engineers make informed decisions.
Product Description
- Type: Expandable Polystyrene (EPS)
- Characteristics: FC422 is noted for its fast cycling capabilities and is formulated to be waterproof. It contains spherical polystyrene beads with pentane as the expansion agent, which aids in achieving low-density foam without lumps during pre-expansion.
- Special Features: This grade is not fire retardant, making it unsuitable for building applications where fire resistance is necessary.
Key Applications
- High Density Block: Ideal for creating high-density EPS blocks used in various construction and packaging applications.
- Shape Molding: Well-suited for contour moldings with wall thicknesses of less than 10 mm, making it perfect for intricate designs and applications requiring precise detail.
- Packaging Solutions: The material's impact absorption properties make it excellent for protective packaging that needs to cushion contents against external shocks.
Handling and Processing
- Packaging and Storage: FC422 is packaged in octabins, each containing 1000 kg of material. These containers are not weather- or waterproof and should be stored indoors, below 20°C, and used within one month to maintain optimal properties.
- Pre-expansion: Achievable at densities around 25 kg/m³ using discontinuously operating, state-of-the-art preexpanders. Lower densities can be achieved through double pre-expansion or optimized machines.
- Molding: Can be processed on standard industry molding machines with a wide range of steaming settings. If using a regenerative agent, it should closely match the pre-expansion density to avoid segregation during production.
Typical Properties
- Bead Size: 0.5-0.7 mm, ensuring consistency and quality in final products.
- K-Value: Typically falls between 52-57, which indicates the level of thermal insulation the material provides.
- Pentane Content: At least 5.2%, essential for effective expansion.
- Expanded Density: Ranges from 20 to 30 kg/m³, depending on the specific application and equipment used.
- Residual Monomer: Up to 1000 ppm, reflecting the purity of the material and its compliance with safety standards.
Regulatory Compliance
- Antistatic Treatment: FC422 is treated with an antistatic agent to reduce the buildup of static electricity during transport, which is crucial for handling and safety.
Summary
FC422 from Tabriz Petrochemical Company offers robust solutions for applications requiring fast cycling EPS with specific mechanical properties. Its ability to form high-density, detailed molded products makes it a valuable choice for manufacturers seeking efficient, high-quality EPS solutions for packaging, construction, and intricate moldings. The material's handling, storage, and processing specifications ensure that FC422 maintains its quality and performance from production to application, solidifying its role as a go-to material in various industries.
