Polycarbonate, commonly abbreviated as PC, is a type of engineering plastic known for its excellent mechanical and thermal properties. PC 136, 21666664 is one specific grade of polycarbonate material widely used in industrial applications. As a globally popular material, PC offers a unique combination of benefits and limitations that make it suitable for a wide range of uses.
PC is an amorphous thermoplastic with outstanding electrical insulation, dimensional stability, and chemical resistance. It can withstand high temperatures up to 160°C and has good cold resistance down to -60°C. Additionally, it is flame-retardant, self-extinguishing, non-toxic, and easily colored. These characteristics make it ideal for various consumer and industrial products. Due to its ease of processing and large-scale production, PC is also cost-effective and widely available.
In terms of strength, PC is capable of meeting the demands of everything from mobile phone casings to bulletproof glass. However, it is not as hard as metal, making it more prone to scratches. Despite this, its toughness and impact resistance are remarkable, allowing it to endure heavy pressure and general impacts without breaking—unless subjected to extreme force like being hit by a stone. PC can be manufactured in large diameters, up to 600 mm, and is resistant to both acids and alkalis.
In the construction industry, the term "PC" can have two different meanings depending on the context:
1. **Prefabricated Concrete (PC)**: This refers to concrete components that are manufactured off-site and then assembled on-site. It includes prefabricated structural elements and construction methods that streamline building processes.
2. **Prestressed Concrete (PC)**: This involves the use of prestressed materials and structures to enhance the strength and durability of concrete. It often includes color PC tubes and other specialized components used in modern construction techniques.
Because both definitions are referred to as "PC," it's important to clarify the context when using the term to avoid confusion. Adding Chinese explanations or additional details when communicating about PC materials can help prevent misunderstandings.
PC tubes, also known as polycarbonate tubes, are a type of transparent plastic tubing with high light transmission (up to 92%), earning them the nickname "plastic crystal." They offer excellent weather resistance, especially for outdoor applications, and outperform many other plastics in terms of durability. PC tubes also have good surface hardness, luster, and flexibility, making them easy to shape into various forms and products.
