Plastic is a common material that is widely used in various industries. Plastic PC and plastic PS are two common plastic materials, and they have certain differences in performance, characteristics and application scenarios. This article will give you a detailed introduction to the difference between plastic PC and plastic PS, and their application in different fields. The difference between plastic PC and plastic PS Let us understand the basic characteristics and differences between plastic PC and plastic PS. Plastic PC, the full name of polycarbonate, is an excellent engineering plastic, with excellent mechanical properties, thermal stability and weather resistance, good transparency and heat resistance, almost insoluble in general organic solvents at room temperature, but soluble in benzene, methanol, acetone and so on. Plastic PS, the full name of polystyrene, is a common plastic material, with light texture, durable, low cost characteristics, but the tensile strength, impact resistance and heat resistance are poor. The difference between plastic PC and plastic PS is mainly reflected in the following aspects: 1. Strength and toughness Plastic PC has relatively high strength and toughness, has good mechanical properties and impact resistance, and is not easy to break. The strength and toughness of plastic PS is relatively poor, and it is prone to fracture and deformation. 2. Transparency Plastic PC has excellent transparency and can be used as a transparent material. It is suitable for making optical parts, car lampshades, safety glasses and other products. The transparency of plastic PS is poor, and it is often used to make general daily necessities and packaging materials. 3. High temperature resistant plastic PC high temperature resistant performance is better, long-term use temperature can reach more than 120 ℃, even high temperature 140 ℃ hot water. The plastic PS heat resistance is poor, long-term use temperature is generally about 60 ℃. The cost of plastic PC is higher, but the performance is relatively superior and the use is more extensive. The cost of plastic PS is lower and it is suitable for the production of some disposable products. Application scenarios of plastic PC and plastic PS In different application scenarios, both plastic PC and plastic PS have their unique characteristics and advantages, so it is necessary to make a reasonable choice according to actual needs when selecting materials. Plastic PC in the automotive, electronics, medical equipment, construction and other fields have a wide range of applications: auto parts such as car lampshade, rearview mirror shell, etc.; electronic products such as CD, mobile phone screen, etc.; medical equipment such as infusion bottles, medical instruments, etc.; construction areas such as heat insulation board, sun visor, etc. Plastic PS is mainly used in daily necessities, packaging materials and short-term high-temperature products, such as disposable tableware, fresh-keeping boxes, packaging boxes, thermos cups, etc. As common plastic materials, plastic PC and plastic PS have their own unique characteristics and advantages in different application fields. Understanding their differences and application scenarios can help us choose suitable materials more reasonably in actual production and use, thereby improving product performance and quality. I hope this article can help you, thank you for reading!
