Modified Polystyrene[2]
Overview
Modified Polystyrene is a polymer material derived from polystyrene, enhanced with rubber or other additives to improve its mechanical and thermal properties. This modification significantly increases its impact resistance, making it suitable for applications requiring durability and toughness. Commonly referred to as High-impact Polystyrene (HIPS), this material retains the ease of processing and cost-effectiveness of standard polystyrene while offering superior performance in demanding environments. It is widely used in industries such as packaging, automotive, and consumer goods.
Physical and Chemical Properties
Modified Polystyrene exhibits a density range of 1.04-1.06 g/cm³ and a melting point between 180-240°C, depending on the specific formulation. Its key properties include high impact resistance, good dimensional stability, and ease of processing through methods like injection molding and extrusion. The material is insoluble in water but dissolves in aromatic hydrocarbons, ketones, and chlorinated solvents. Its thermal stability and resistance to environmental stress cracking make it a preferred choice for applications requiring durability under varying conditions.
Main Applications
Modified Polystyrene is extensively used in the packaging industry for producing containers, trays, and clamshells due to its impact resistance and lightweight properties. In the automotive sector, it is employed for interior trim components, dashboards, and other parts requiring durability and ease of fabrication. Consumer goods such as toys, electronic housings, and household items also benefit from the material's versatility and cost-effectiveness. Its ability to be easily colored and molded into complex shapes further expands its application range.
Safety and Storage
Modified Polystyrene is generally safe for handling, but precautions should be taken to avoid inhalation of dust and prolonged skin contact. Proper ventilation is recommended during processing to minimize exposure to fumes. Storage conditions should include a cool, dry environment away from direct sunlight and heat sources to prevent degradation. The material should be kept in sealed containers to avoid moisture absorption, which can affect its processing properties.
B2B Procurement Guide
When procuring Modified Polystyrene, specify the required impact strength, thermal stability, and processing method to ensure the material meets your application needs. Verify supplier certifications, such as ISO or ASTM compliance, to guarantee quality and consistency. Price ranges typically fall between $1.50-$3.00 per kg, depending on the grade and quantity ordered. Bulk purchases may qualify for discounts, and it's advisable to request samples for testing before large-scale procurement.
