Overview
PS105 is a type of polystyrene, a synthetic aromatic polymer made from styrene monomers. It is widely used in various industries due to its excellent rigidity, transparency, and ease of processing. PS105 is a general-purpose polystyrene (GPPS) variant, known for its clarity and brittleness. Polystyrene materials like PS105 are produced through polymerization processes, which can be tailored to achieve specific properties. The material is favored for applications where transparency and stiffness are required, though it lacks the impact resistance of high-impact polystyrene (HIPS).
Physical and Chemical Properties
PS105 exhibits a density of approximately 1.04-1.06 g/cm³, making it a lightweight material. It has a melting point around 240°C, which allows it to be easily molded or extruded into various shapes. The material is insoluble in water but dissolves in organic solvents such as toluene and benzene. One of the key characteristics of PS105 is its transparency, which makes it suitable for applications requiring see-through components. However, it is relatively brittle and can crack under stress, limiting its use in high-impact environments.
Main Applications
PS105 is commonly used in the production of disposable cutlery, CD and DVD cases, and packaging materials. Its transparency and rigidity make it ideal for these applications. The material is also used in the manufacturing of toys, cosmetic containers, and household items. In the medical field, PS105 is utilized for Petri dishes and other laboratory equipment due to its clarity and sterility. However, its brittleness means it is less suited for applications requiring durability, such as automotive parts or heavy-duty containers.
Safety and Storage
PS105 is generally considered non-toxic, but precautions should be taken to avoid inhaling dust or fumes generated during high-temperature processing. Proper ventilation is essential when working with this material. Storage conditions for PS105 include keeping it in a cool, dry place away from direct sunlight to prevent degradation. The material is stable under normal conditions but can release styrene monomers if overheated, which may pose health risks.
B2B Procurement Guide
When procuring PS105, buyers should verify the material's purity and grade to ensure it meets the requirements of their specific application. Prices typically range from $1.50 to $3.00 per kg, though this can vary based on quantity and supplier. It is advisable to request material safety data sheets (MSDS) and certificates of analysis (COA) from suppliers. Bulk purchases may offer cost savings, but storage capacity should be considered to maintain material quality over time.
