What are the pc material classifications
1. The classification of PC materials mainly includes the following categories: polycarbonate board: This is a transparent or translucent plastic board with good light transmission, impact resistance and weather resistance. Widely used in construction, advertising, lighting, automobiles and other fields. PC alloy materials: In order to improve certain properties of PC materials, they are often combined with other materials to form alloys. For example, mixing with ABS or other plastics can improve the processability and mechanical strength of PC materials.
2. There are more than 7600 known models of PC materials. These models were mainly developed based on the different characteristics and uses of polycarbonate, a polymer.
3. Classification of aliphatic polycarbonates according to the ester structure: These PC materials have relatively low mechanical properties, so they are limited in some engineering plastic applications with high mechanical properties. Aromatic polycarbonates: Compared with aliphatic polycarbonates, aromatic polycarbonates generally have better mechanical properties and thermal stability, so they are more widely used in the field of engineering plastics.
4. There are many types of PC materials. PC material, scientific name polycarbonate, is a high-performance polymer material. Due to its excellent physical, chemical and processing properties, PC materials are widely used in many fields and come in many different types. Die-casting PC classified by manufacturing process: This PC material is formed by high-pressure die casting and has extremely high strength and heat resistance. It is usually used to make high-performance parts.
5. This classification method is mainly based on the different structures of carbonate groups in their molecular chains, resulting in differences in material properties. Differences in mechanical properties: Aliphatic and aliphatic aromatic polycarbonates have relatively low mechanical properties, which limits their application in the field of engineering plastics. Aromatic polycarbonates usually have good mechanical properties, so they are widely used in the field of engineering plastics.
Covestro PC in-depth analysis:2805, 2405, 2407, 2807, 2456, 6555, 6557 models are comprehensive...
In-depth analysis of Covestro PC: Comprehensive interpretation of the 2802402802456556557 model Covestro PC is a high-performance polymer material. With its excellent performance and reliable quality, it has been widely used in many fields such as automobiles, electronics, construction, and medical care.
The main difference between Germany's Covestro (Bayer) 2805 and 2807 is that the 2807 has ultraviolet resistance, while the 2805 does not.
The main difference between PC Covestro 2807 and 2407 is flow and impact properties. The following is a detailed comparison of the two materials: Flowability: 2807: It is a medium viscosity material with relatively good flowability. This means that during injection molding, 2807 can flow and fill the mold more easily, helping to produce complex shaped or thin-walled products.
How to eliminate static electricity in PC materials
Add antistatic agents in material modification methods: You can mix built-in antistatic agents (such as quaternary ammonium salts and non-ionic surfactants) during PC material processing to reduce resistance by migrating to the surface of the material to form a conductive layer; or use external-coated antistatic agents (such as antistatic coatings) to form a lasting hydrophilic film on the surface of the product to absorb moisture in the air and conduct electricity.
Environmental humidity control: Keep the humidity in the production workshop at 40%-60%. The increase in humidity can enhance the conductivity of the PC material surface and reduce static electricity generation, which can be achieved through a humidifier.
Static electricity in PC materials can be eliminated by the following methods: Adding conductive ingredients Add 0.1%-5% conductive additives such as carbon fiber, carbon black or metal powder during the production process, which can significantly improve the conductivity of PC materials and reduce static electricity accumulation. In addition, polystyrene (PS), polyethylene (PE), polypropylene (PP), polyamide (PA) and other materials can also be used as auxiliary additives to further optimize electrical conductivity.
After PC material generates static electricity, appropriate methods can be selected based on production or use scenarios to effectively eliminate static electricity elimination during production and processing. 1) Add antistatic agents, such as quaternary ammonium salts and non-ionic antistatic agents, to the PC material, and form a conductive layer on the surface through migration, reducing surface resistance. The antistatic effect is long-lasting, and is suitable for pre-molding treatments such as injection molding and extrusion.

What are the ingredients of pc black particles?
The core basic component of PC black particles is polycarbonate (PC). On this basis, different modified excipients will be added according to the product use. Common types and corresponding components are as follows: Universal modified PC black particles are based on pure polycarbonate. Carbon black is added as a colorant, and some antioxidants and light stabilizers are added to improve aging resistance, ensure the strength and heat resistance of the foundation and present a black appearance.
When burning, special odors produce mixed characteristic odors: rubber-like burnt smell from ABS components; sweet and greasy smell of styrenic substances, which is a typical manifestation of the decomposition of butadiene rubber in ABS. Residue analysis After combustion, it can be seen: black hard carbonized particles with irregular shape; the residue is hard in texture and is not easy to crush when pressed lightly with tools. This is a direct reflection of the heat resistance of PC components.
The price of recycled plastic particles recycled particles are processed from recycled PC products, and the price is affected by cleanliness and processing technology. The starting price of black PC recycled plastic granules in Shunbang, Jinan, Shandong Province is 5 yuan/kg (November 2025) to 5 yuan/kg (September 2024). The difference may be related to market conditions and batches.
Jinfa Technology Co., Ltd. is a leading domestic company in modified plastics. It leads the industry in production capacity and brand awareness. The output of flame-retardant PC particles ranks among the top, and the supply chain system is complete. The products are mainly general purpose types, with flame retardant ratings reaching UL94V0. They have strong processing fluidity and product stability. They are mainly used in conventional scenarios such as electronic and electrical, home appliance casings, etc.
What are the components of PC?
Raw materials and chemical properties PC endurance board: It is made of polycarbonate as the main component and is made of co-extrusion technology. It is resistant to neutral oils, but not acid or alkali.
The composition of PC components mainly includes the following: Basic components of polycarbonate: Bisphenol A Bisphenol A is the main raw material for manufacturing polycarbonate. It is the basic chemical unit of synthetic materials and is directly related to the overall performance of polycarbonate materials. It has good thermal stability and mechanical properties. Auxiliary ingredients In order to improve the performance or processing characteristics of polycarbonate, some auxiliary ingredients, such as plasticizers, anti-ultraviolet agents, flame retardants, etc., are added.
The main differences between PC, PE, PP, PVC, PET, and PMMA are reflected in chemical composition, physical properties, application scenarios and safety. The details are as follows: PC (polycarbonate) characteristics: high transparency, good thermal stability, but poor hand feeling and easy to show dirt, belonging to engineering plastics. Applications: phone case, notebook computer case, milk bottle, space cup, etc.

Chemical structure and synthesis method PC: With polycarbonate as the main component, it is processed and formed through co-extrusion technology. Its molecular chain contains carbonate groups, giving the material high strength and toughness. PVC: Produced by free radical polymerization of vinyl chloride monomer, it is divided into vinyl chloride homopolymers and copolymers. The chlorine atoms in its molecular chain give it unique flame retardancy and chemical stability.
