High Impact Opacity PC

Updated: 2026-09-13

Overview

High Impact Opacity PC is a modified polycarbonate engineered to combine high impact resistance with effective light-blocking capabilities. This material is particularly valued in industries where both durability and opacity are critical, such as automotive manufacturing and electronics. Polycarbonate is inherently tough, but the addition of impact modifiers and opacity-enhancing additives makes this grade suitable for applications requiring structural integrity and privacy or light control. The material is also often UV-stabilized to enhance outdoor performance.

Physical and Chemical Properties

High Impact Opacity PC retains the core properties of standard polycarbonate, including high tensile strength and thermal resistance, while adding superior opacity and enhanced impact resistance. The material typically has a density of 1.2–1.4 g/cm³ and a melting point around 220–250°C. Chemical resistance is another notable feature, with the material being insoluble in water and resistant to many organic solvents. However, it can be attacked by strong bases and some chlorinated hydrocarbons. The opacity is achieved through additives like titanium dioxide or carbon black, which also contribute to UV resistance.

Main Applications

This material is widely used in automotive components such as interior trim and light housings, where opacity and durability are essential. In electronics, it is used for housings and covers that require both protection from impacts and light shielding. Construction applications include skylight panels and noise barriers, where the material’s opacity and weather resistance are advantageous. The medical industry also uses it for equipment housings that need to block light while withstanding frequent sterilization processes.

Safety and Storage

High Impact Opacity PC is generally safe to handle but should be stored in a dry, cool environment to prevent degradation. Prolonged exposure to moisture can affect its mechanical properties, so sealed packaging is recommended for long-term storage. When processed at high temperatures, the material may release fumes, so adequate ventilation is necessary. It is non-toxic under normal conditions but should not be ingested or inhaled as dust during machining. Proper personal protective equipment (PPE) like gloves and masks should be used during handling.

B2B Procurement Guide

When procuring High Impact Opacity PC, buyers should specify requirements such as opacity level (measured by light transmission percentage), impact resistance (often tested via Izod or Charpy tests), and UV stabilization. Custom formulations may be available for specific applications. Suppliers typically offer the material in granules or sheets, with prices ranging from $3 to $8 per kilogram depending on grade and order volume. Bulk purchases may qualify for discounts. It’s advisable to request material data sheets (MDS) and samples to verify properties before large-scale procurement.
