General-Purpose PC is an amorphous engineering thermoplastic used mainly for injection molding. It combines impact strength, dimensional stability, transparency, and heat resistance with processing characteristics suitable for standard molded components. The appropriate grade depends on the required flow, mechanical performance, appearance, and end-use conditions.
Nianjing is a plastic raw material trading and sourcing company based in China Plastics City, Yuyao. The company sources polycarbonate resin from established producers, including Idemitsu, according to the required manufacturer, grade, specification, quantity, and delivery destination.
| Item | Details |
| Material | PC (Polycarbonate) |
| Material Type | Amorphous engineering thermoplastic |
| Processing | Injection molding |
| Form | Pellets / Granules |
| Representative Grade | PC IR2200, Idemitsu |
| Typical Appearance | Natural / transparent |
| Supply | Subject to current grade and inventory availability |
General-purpose polycarbonate is selected when a molded part needs a combination of toughness, heat resistance, dimensional stability, and appearance. Exact performance varies between grades, so the manufacturer's TDS should be used when a specific property is critical.
| Property | Typical Consideration |
| Impact Strength | Suitable for parts exposed to mechanical impact |
| Dimensional Stability | Helps maintain part dimensions during service |
| Heat Resistance | Higher than many commodity thermoplastics; grade-specific values should be checked |
| Transparency | Natural PC can provide high light transmission |
| Flow | Varies with molecular weight and grade viscosity |
| Surface Finish | Suitable grades can provide a smooth molded surface |
| Moisture Sensitivity | PC requires controlled drying before processing |
For production decisions, grade-specific data such as MFR, tensile strength, impact strength, HDT, Vicat softening temperature, and light transmittance should be checked against the current producer datasheet.
The material is used for molded components where mechanical strength and dimensional stability are important.
Connector housings, switch components, relay parts, charger housings, and other molded electrical components.
Housings and covers for selected household and electrical appliances where impact and heat resistance are required.
Selected interior, lighting, trim, and non-structural components. The required grade should be matched to the temperature, impact, chemical, and OEM requirements of the part.
Transparent covers, protective components, durable housings, and other molded products.
Housings, covers, gauges, and mechanical components requiring dimensional stability and impact resistance.
Nianjing can source commonly traded polycarbonate grades according to customer specifications.
A medium-viscosity polycarbonate grade used for injection molding and general-purpose applications.
Materials from Idemitsu, Taiwan Hsing, Ascend, Dow, DuPont, and other producers can be checked according to the required grade and specification. Availability depends on the current supply situation.
When the customer already has a specified grade, Nianjing can check the corresponding sourcing option rather than substituting another material without confirmation.
Polycarbonate absorbs moisture from the environment and should be dried before injection molding. Drying temperature, time, and allowable moisture level should follow the resin manufacturer's processing recommendations.
As a general processing reference, many PC grades are dried at around 120°C for several hours before molding. Injection and mold temperatures vary according to grade viscosity, part design, mold construction, and equipment, so the specific TDS should take precedence over a fixed processing range.
Poor drying can contribute to:
Processing conditions should be established through the selected grade's technical data and production trials rather than applied as a universal setting.
The main difference is the performance priority of the formulation.
| PC Category | Main Focus | Typical Use |
| General-purpose | Balanced flow and mechanical properties | Standard injection-molded parts |
| Optical | Light transmission, haze, optical quality | Optical components |
| Glass-fiber reinforced | Stiffness and dimensional performance | Structural or rigid components |
| Flame-retardant | Flame performance | Electrical and electronic applications |
| High-flow | Easier filling of complex or thin-wall parts | Specific injection molding applications |
For polycarbonate sourcing, provide as much of the following information as available:
| Requirement | Information to Provide |
| Material | PC / Polycarbonate |
| Manufacturer | Preferred producer, if specified |
| Grade | Exact grade or required performance |
| Application | End product or component |
| Processing | Injection molding or other process |
| Quantity | Required order quantity |
| Color | Natural or specified color |
| Packaging | Standard or specified packaging |
| Destination | Delivery country or port |
Nianjing can check the corresponding producer, grade, availability, and supply conditions based on this information. If no specific grade has been selected, the application and processing requirements can be used as the starting point for basic material selection.
Polycarbonate resin is normally supplied in producer-standard bags or other agreed packaging formats. Actual packaging, quantity per package, available inventory, and delivery schedule depend on the selected producer and grade.
For a quotation, customers can provide the required grade, manufacturer, quantity, and destination. Nianjing can then confirm the applicable sourcing and supply conditions.
A: It is a standard polycarbonate material for injection molding, offering a balance of impact strength, dimensional stability, heat resistance, transparency, and processing performance for general molded components.
A: Optical grades focus more on light transmission and low haze, while reinforced grades use materials such as glass fiber to increase stiffness and strength. The appropriate category depends on the part's performance requirements.
A: Yes. PC is moisture-sensitive and should be properly dried before processing. The drying temperature, time, and moisture limit should be taken from the selected producer's processing guidelines.
A: Yes. Customers can provide the manufacturer, grade, specification, and quantity. Nianjing can check the corresponding sourcing and supply conditions.
A: The most useful information includes the required grade or manufacturer, quantity, application, color or specification, and delivery destination. If the grade is not known, the application and processing method can be provided for initial material selection.
