Is PC A Part Of The Big Family Of Plastics?
To assign PC's category rightly,we first have to know the nature of plastics and then specifically study PC's distinct structure.
The Nature of Plastics
Plastics are primarily composed of polymers of high molecular weight.They can be formed at specific temperature and pressure and are capable of retaining their shape at room temperature.Their chain molecular structure endows them with properties such as plasticity and insulation,making many uses possible.
Special Structure of PC-Carbonate Groups
PC or polycarbonate is a plastic of high molecular weight and completely satisfies the definition of a plastic and belongs to the large family of plastics.Its heart and soul is its carbonate group(-O-CO-O-)within its molecule,which gives PC superb attributes like good strength,high transparency,and proper heat resistance,and therefore it stands tall in specialized application.
Since we have established PC's class,the question that follows is:how do we choose the appropriate PC grade for different applications?
We understand perfectly well the character of PC and the benefits of carbonate groups,and can offer personalized PC solutions of high strength,high transparency,and other properties.In case you require PC application,select us and enjoy JS precision manufacturing and processing ability for expert advice and smooth project execution.
How To Select The Correct PC Grade?
Different applications require different PC performance,and PC comes in different grades.Choosing the right level is crucial in balancing performance and cost.
By Impact Strength
- Normal Impact Strength PC: Provides moderate impact strength and can be utilized in applications with low impact requirements,such as office equipment housings and inner components of domestic appliances,at an affordable price.
- High Impact Strength PC: PC altered to a great extent enhances impact strength and is used in safety-critical applications,e.g.,car bumpers and helmets,effectively protecting users.
By Heat Resistance
- Medium Heat Resistance PC: Offers heat resistance of 120°C-150°C,including day-to-day and general industrial use,e.g.,food contact containers and electronic component housings,and withstands deforming at higher temperatures.
- High-heat-resistant PC: Heat-resistant at over 150°C,some grades up to above 200°C.Employed in automobile engine peripheral components and LED heat sinks,and provides dependable performance even at higher temperatures.
Classification by Transparency
- Transparent PC: With more than 90%light transmission,it is virtually like glass but lighter and shock-resistant.Used in eyeglass lenses,cell phone screen protectors,and greenhouse skylights for light transmission as well as drop resistance.
- Translucent/Opaque PC: Masterbatches or modifiers are incorporated to reduce light transmittance.Used in appliance casings and automotive trim to meet a wide range of aesthetic requirements.
Choosing the right PC grade matters in production,and PC is used when high performance beyond regular plastics is needed.Let's discover the key to PC being more than plastic.

PC Materials Finishing:Various Processing Methods For Finishing PC Pellets
Various methods are employed to finish PC pellets into finished products,and among them,injection molding is the most prevalent.
Injection Molding
Injection molding involves heating and melting of PC pellets,injecting them into a mold,and afterward cooling them to form the final product.It is highly effective and can mass-produce high-tech products.
JS Precision Manufacturing is expert in manufacturing premium injection molding parts,online injection molding service allows customers to enter their requirements and get customized solutions,customized injection molding production provides one-stop service from design to production.
Laser Cutting
Using a high-energy laser beam to cut PC sheets,it features high accuracy,smooth cutting,and zero mechanical stress.It can be used for processing high-precision,complex products such as decorative panels and electronic protective covers.
Power and speed have to be adjusted according to sheet thickness.The thicker the sheets,the higher power and slower speed.It requires no mold,and therefore it is suitable for small-batch,high-variety production.
CNC Machining
Machine tools controlled by the computer drill and mill PC sheets to high precision with good repeatability.It is suited for complex,high-precision products such as precision instrument casings and mechanical transmission components.The right tooling and parameters must be selected in order to avoid sticking of tools and surface roughness.High-precision hole and thread cutting can also be obtained.
3D Printing
Additive manufacturing technology builds PC material layer by layer without mold demand.It is used for R&D prototyping and small-volume customization.
Special PC filament or powder is required.The product performance and precision are enhanced,but the process speed is reduced and the strength is less than injection molded products.Currently,its application is growing in areas such as customized phone cases and glasses frames.
Now that we know about PC processing methods,let's put PC and glass against one another to understand which one is the 'King of Drop Resistance'.
We specialize in PC injection molding,CNC,3D printing,and other processes,and offer online injection molding services.Upload your design to receive a quote.With JS precision manufacturing,we can assist you in streamlining your PC parts production process efficiently.
PC vs.Glass:Which One Is Truly The 'King Of Drop Resistance'?
Glass is clear and heat-resistant,but brittle.PC is clear and incredibly tough as well.The two are very different,though,when it comes to impact strength,density,and light transmission.The relative values are presented in the table below,clearly indicating which offers superior drop resistance:
Performance Indicators | PC(Polycarbonate) | Glass | Advantages of PC |
Impact Strength(kJ/m²) | 60-80 | About 1 | The anti drop performance far exceeds that of glass, and the risk of damage is extremely low. |
Density(g/cm³) | 1.20 | 2.50 | More lightweight, can reduce transportation, installation, and usage costs. |
Light Transmittance(%) | 90-92 | 90-95 | The light transmittance is comparable, making PC more suitable for scenarios such as children's rooms and sports venues. |
Temperature Difference Resistance(°C) | Resists between-40°C and 120°C | Easily shatters with extreme changes in temperature. | Good temperature resistance. |
Weight(for the same volume) | Lighter | Heavier | Can reduce the burden on the supporting structure. |
Clearly,PC is the undisputed 'king of drop resistance' with advantages in terms of density and thermal resistance.It is also taking over for glass in applications such as building skylights and auto windows.

FAQs
Q1:Is PC material safe? Can it be used for food contact?
The safety of PC materials depends on the specific type. It is feasible to use them for food contact, but there is a key prerequisite - food grade PC materials that have passed authoritative certification must be selected. This type of material does not contain harmful ingredients such as bisphenol A (BPA), and its safety is guaranteed.
Q2:Why does my PC component border become white during laser cutting?
The whitening of the edges of PC parts during laser cutting is mainly caused by thermal stress generated during the cutting process. Excessive heat concentration can cause changes in the material of the edges of the parts, resulting in whitening. To improve this problem, it is necessary to optimize the core parameters of laser cutting, such as adjusting power, cutting speed, and gas pressure, to reduce heat input.
Q3:What documents do I need to provide for my project?
If your project involves laser cutting or CNC machining, two types of files need to be provided:
- Vector files, commonly in formats such as DXF and AI, which facilitate precise cutting.
- 3D model files, such as STEP and STL formats, which can meet complex machining requirements.
At present, our online platform supports uploading these files, and after uploading, processing quotations can be obtained instantly.
