Conductive Compounds
Controllable electrically conductive performance
Electrically conductive plastic is a modified plastic compound composed of conductive fillers, base resins, and special additives through physical or chemical methods that have good electrically conductive properties. Common conductive fillers include carbon black, CNT, conductive metal powder, carbon fiber, etc., and the base resin matrix includes plastic, rubber, etc. The conductivity value of the conductive compound can be adjusted by the dosage of conductive fillers. The surface resistivity and volume resistivity of electrically conductive plastics are relatively low, usually below 10E9 ohms, and have excellent conductivity and mechanical properties.
A Conductive masterbatch is a kind of conductive compound with conductive fillers. The conductive fillers are evenly dispersed in carrier resin (usually high molecular polymers) and made into a functional masterbatch with high conductive properties through a specific process. The role of conductive masterbatch is to facilitate the uniform addition and stable performance of conductive properties in subsequent products, and it is easy to use. It can be directly mixed with the base resin in a certain proportion, reducing the complex process of on-site preparation of conductive fillers and improving production efficiency. Conductive masterbatch can ensure the consistency of conductive properties. Since the conductive filler has been evenly distributed in the masterbatch, it can provide the conductivity stability and conductivity uniformity of the electrically conductive plastic.
Applications of INCHR@Electrically conductive plastic
Electromagnetic shielding materials field: Can limit the energy transfer of electromagnetic waves and reduce the magnetic field strength or radiation intensity. For example, metal foil and metal fiber are added to plastics to make electrical conductive plastics for electromagnetic wave shielding. Electrical conductive plastics protect electronic equipment and personnel from interference from external electromagnetic waves.
Electronics field: Used to produce electronic product housings and parts, such as housings and internal connecting wires of mobile phones, computers, cameras, televisions, and other household appliances. Electrical conductive plastics can make the electric field in electronic devices evenly distributed and protect the normal operation of electronic devices. At the same time, its lightness and easy processing characteristics also meet the requirements of electronic products for miniaturization and lightweight parts.
Energy field: Used in solar cells, as an electrode material for solar cells, to improve the photoelectric conversion efficiency of solar cells. The flexibility and processability of conductive plastics can also make the manufacture of solar cells simpler and more cost-effective. It can also be used to produce electrode materials for supercapacitors, with high specific capacitance and good cycle performance, which can improve the energy storage capacity of supercapacitors.
Automobile field: It can be used to manufacture electrical components such as wires, cables, sensors, etc. for automobiles, providing transmission signals and power supply for automobiles. In addition, conductive plastics can also be used in automobile bodies, frames, wheels, and other parts, which helps to reduce automobile weight and improve fuel efficiency. Electrically conductive plastics can be used in automobile dashboards, seats, interior panels, and other parts to improve automobile safety and comfort.
Mining industry: In mines, the friction between many equipment and pipelines can easily generate static electricity, and the accumulation of static electricity may cause serious accidents such as gas explosions. Pipes made of conductive plastics can conduct static electricity away promptly, thereby effectively reducing the safety risks caused by static electricity.
INCHR@Electrically conductive plastic comes to a trend replacing metal
Designability of electromagnetic shielding performance: Electrically conductive plastics with different shielding effectiveness can be designed according to the electromagnetic shielding requirements of the product to meet the electromagnetic shielding needs of electronic equipment, communication equipment, etc. However, the electromagnetic shielding performance of metal materials is relatively fixed and difficult to adjust according to specific needs. The EMI shielding effect is mainly achieved by reflecting electromagnetic waves on the material surface (especially the frequency below 10GHz) and absorbing when wave penetrating materials, the total efficiency of any EMl shielding material is equal to the sum of reflection and absorption. The stronger the conductivity of the electrically conductive plastic, the stronger the reflection effect will be taken; the stronger the magnetic properties or the thicker the thickness of it (related to the depth of the skin), the stronger the absorption effect will be taken. Metal is the most widely used EMI shielding material, Aluminum alloy, and other commonly used metal materials mainly rely on reflection, but almost no absorption.
Good corrosion resistance, long service life: INCHR@ Electrically conductive plastic is often prepared with high-performance engineering plastics (such as ABS, PC, PBT, ABS+PC, PPO, PPA, PPS, etc.) as base material, it has good corrosion resistance, processability, and low production energy loss. After a salt spray exposure test (360 hours, 5% NaCl solution, 35 degrees,95% relative humidity [ASTM B117] ), the conductive compound has strong corrosion resistance, it is an ideal choice for harsh outdoor environments.
Low density, reduces transportation costs: The density of INCHR@Electrically conductive plastic is only 1/4 of common metals, even half of aluminum’s (density is 1.2-1.4g/cm, aluminum density is 2.7g/cm3). Due to the low density and the possibility can be processed into a thin wall structure (about 1.0mm, half of aluminum casting), the weight of the final finished part was reduced by 755%. Although the thickness is greater than the stainless steel parts, the overall weight can be reduced by 50% after the replacement.
Easy to process and shape: The electrically conductive plastic can be formed through various plastic processing methods such as injection molding, extrusion, blow molding, etc., and can quickly and efficiently manufacture products of various complex shapes. In contrast, metal processing usually requires complex processes such as casting, forging, and machining, which are difficult to process and costly, and it is even more difficult to process parts with complex shapes. The easy processability of electrically conductive plastics allows designers to have greater freedom in product design. They can design unique shapes and structures according to needs to meet the personalized needs of different application scenarios.
