Black PC Rods Dia 150mm Polycarbonate Solid Bar

Black PC Rod features a smooth surface (roughness Ra < 0.2μm), uniform color (no color difference ΔE < 1.5), and a density of 1.20-1.22g/cm³. Common diameters range from 3mm to 150mm (some manufacturers can customize up to 200mm), and lengths typically come in 1m, 2m, or 3m (cutting is possible on demand). Depending on the application, it can be divided into standard grade (for general mechanical/electronic components), optical grade (translucent black PC with retained light transmittance), reinforced grade (with added glass fiber for increased rigidity), high-temperature grade (modified to withstand short-term temperatures of 180°C), and anti-static grade (surface resistivity of 10⁶-10⁹Ω). It is widely used in electronics, optical instruments, industrial equipment, security, and consumer electronics.

Product Advantages

High Impact and High Temperature Resistance

Black PC rods' ultra-high impact resistance (over 600 J/m) and wide temperature range (-40°C to +120°C) make them the preferred choice for critical components in electronic appliances and industrial equipment requiring both drop and temperature resistance. For example:

Industrial control panels: Used in operating panels for machine tools and automated equipment. Their oil and lubricant resistance and impact resistance ensure long-term crack-free use (lifespan > 5 years).

LED lamp brackets: Their opaque black color (completely shielding light) combined with high temperature resistance (LED chips operating at temperatures below 80°C) ensures they are used as internal support structures for spotlights and downlights, preventing light leakage and withstanding high temperatures.

Optical Auxiliary - Concealed Transmission

For applications requiring concealed transmission (such as indicator light hoods) or complete light shielding (such as lens shading rings), black PC rods can achieve translucent or opaque designs by adjusting the carbon black content. For example:

Optical Instrument Auxiliary Components: Light shields for microscopes and lasers (translucent black PC, 10%-30% transmittance) allow specific wavelengths of light to pass through (guiding the optical path) while blocking stray light (improving image clarity);

Consumer Electronic Functional Components: Mobile phone flash hoods and camera module brackets (completely opaque black PC). High blackness (Pantone Black 6C) and surface smoothness (Ra < 0.2μm) prevent reflections from interfering with photographic quality.

Easy Processing and Low Cost

Black PC rods' easy processability (short extrusion/injection molding cycle times) and relatively low cost (raw material prices are 40%-50% lower than POM and 70%-80% lower than PEEK) significantly improve production efficiency. For example:

Mass Production of Plastic Housings: Used in control panels or decorative trims for home appliances (such as rice cookers and vacuum cleaners), black PC rods' high flowability (MFR 10-30g/10min) supports complex curved designs (such as housings with undercuts), while the unit cost is 60%-70% lower than metal (such as aluminum alloy die-castings).

Customized Industrial Parts: Rapidly produce black PC connectors with threaded holes and snap-fit mechanisms (such as sensor brackets) through injection molding. The short cycle time (from design to finished product is less than one week) makes them suitable for small batches and a wide variety of products.

Waste Recycling: Processing waste (such as turning chips) can be 100% shredded and re-extruded, achieving a comprehensive material utilization rate exceeding 95%, reducing production costs.

Specific Application Areas and Components

Electronics and Electrical Appliances

Device Housings and Brackets: Used in the housings and internal brackets of routers, switches, and chargers. The black exterior is dirt-resistant and impact-resistant (resists daily collisions), and its heat resistance (short-term resistance to 140°C) ensures no deformation near power modules.

LED Lighting Components: Serving as sunshades for spotlights and downlights or as heat sink supports, the completely opaque black PC (haze >95%) prevents light leakage while withstanding LED operating temperatures (<80°C).

Switch and Socket Panels: Injection-molded panels made of black PC rods (3-5mm thick) offer insulation (volume resistivity ≥10¹⁴Ω·cm) and wear resistance (Akron abrasion value ≤0.1cm³/1.61km) to ensure safe electrical use.

Optical Instruments

Microscope/Laser Shielding Components: Translucent black PC rods (10%-30% transmittance) are used to guide light of specific wavelengths (such as laser path shielding tubes). The black background reduces stray light interference (improving experimental accuracy).

Photographic Equipment Accessories: Camera tripod mounting rings and lens cover clips (black, high-hardness PC) are scratch-resistant (Rockwell hardness 90-95) and weather-resistant (no yellowing after outdoor use).

Industrial Equipment

Machinery Protective Covers: Transparent/translucent black protective plates (with anti-wear agent) for machine tools and presses allow for observation of internal operating conditions (transmittance optional) and provide impact resistance against metal debris (impact resistance >600 J/m).

Conveyor Belt Guide Rails: Guide rails made of black PC rods (smooth surface + wear-resistant coating) are used in material conveying systems in the food and chemical industries. They are oil-resistant (lubricant-resistant) and low-friction (self-lubricating).
