Virgin Plastic Granules
- Product Details
Virgin plastic granules are raw, high-quality plastic pellets made from new, unused resin. These granules are used as the primary material in manufacturing and molding processes. The specifications for virgin plastic granules can vary depending on the type of plastic and its intended use, but generally, they include the following key parameters:
- Material Type
- Polyethylene (PE)
- Polypropylene (PP)
- Polyvinyl Chloride (PVC)
- Polystyrene (PS)
- Polycarbonate (PC)
- Acrylic (PMMA)
- Nylon (PA)
- Color
Virgin plastic granules are typically available in natural (translucent or opaque white) or can be color-customized based on requirements.
- Size and Shape
- Granule Size: Generally ranges from 1 to 5 mm in diameter. The size may vary based on the specific requirements of the molding process.
- Shape: Usually cylindrical or spherical. Some types may come in irregular shapes depending on the processing methods.
- Density
Specific gravity of the granules, which can impact the weight and overall material characteristics. It typically ranges from 0.90 g/cm³ to 1.40 g/cm³ depending on the plastic type.
- Thermal Properties
- Melting Temperature: The temperature at which the granules melt, which is crucial for setting up molding parameters.
- Glass Transition Temperature: The temperature at which the plastic transitions from a hard, glassy state to a softer, rubbery state.
- Additives and Fillers
Virgin plastic granules may be free from additives and fillers or might be specially formulated with specific additives for enhanced properties (e.g., UV stabilizers, flame retardants).
