Polycarbonate is a common polymer which finds applications from automotive to consumer goods. In this blog, we'll dive into the fascinating world of polycarbonates. We'll explore its unique properties, its manufacturing process, and its range of applications that make it popular in the world of polymers. The global Polycarbonate market is likely to flourish at a moderate CAGR of 4.32% by the year 2034.

Here are some of the main topics we'll cover in this blog:

The Properties: Get to know the details of polycarbonate's remarkable properties like toughness, clarity, and heat resistance.

Applications: Explore the applications of polycarbonate, from lifesaving medical devices to everyday consumer products.


Polycarbonate (PC) stands out as a high-performance thermoplastic polymer. Its molecular structure comprises organic functional groups connected by carbonate groups (–O–(C=O)–O–), granting it a distinctive array of properties. Due to its remarkable compatibility with certain polymers, polycarbonate finds extensive use in blends like PC/ABS, PC/PET, and PC/PMMA. This versatile material is employed in various applications, including compact discs, safety helmets, bulletproof glass, car headlamp lenses, baby feeding bottles, roofing, glazing, and more. With its exceptional toughness, transparency, and thermoplastic nature, polycarbonate remains a sought-after choice across industries, offering a balance of strength, durability, and optical clarity. Its ability to withstand impact, coupled with its transparent quality, renders it indispensable in safety-critical applications like protective gear and automotive components. Moreover, its versatility allows for diverse applications, ranging from consumer products to architectural solutions. Its properties include:

Transparency: PC boasts high transparency, facilitating superior light transmission. It is commonly utilized in applications necessitating optical clarity, like eyeglass lenses and transparent protective shields.

Impact resistance: A standout characteristic of PC is its outstanding resistance to impact. It is virtually indestructible, making it ideal for safety-critical applications such as bulletproof glass, safety goggles, and automotive headlight lenses.

Heat resistance: PC can endure high temperatures without melting or distorting. Its elevated glass transition temperature renders it suitable for applications requiring exposure to heat, such as microwave-safe cookware and LED light covers.

Lightweight: Despite its strength, PC is relatively lightweight. This property makes it favored for weight reduction in industries such as aerospace and automotive.

UV resistance: PC exhibits good resistance to ultraviolet (UV) radiation, making it suitable for applications like greenhouse panels or protective covers for outdoor equipment.

Manufacturing Process

VARIPLANT Process is the main process used to produce Polycarbonate. This process initiates Bisphenol A (BPA) and Diphenyl carbonate (DPC) melting which are then introduced into a raw material melt mixing tank. To ensure high-purity monomer essential for polycarbonate production, purification methods like filtration and impurity removal through stripping are applied. The pre-heated raw materials are then delivered in liquid form into the transesterification reactor. During the initial reaction phase, the raw material melt is combined with catalysts and heated to the specified transesterification temperature, adjusting a specific pre-conversion rate. As monomer and polymer chains develop, phenol begins to separate. Upon completion of transesterification, the produced oligomers are continuously discharged and directed to the prepolycondensation I reactor for the subsequent reaction phase.

By employing elevated temperatures and reduced vacuum conditions, mid-size chain length molecules are formed. Following the prepolycondensation I reactor (PP I), and depending on the plant's production rate design, the system can be configured with one, two, or three polycondensation lines in parallel. This allows for the simultaneous production of up to three distinct product grades. The product from PP I is then transferred to the prepolycondensation II reactor for further chain growth, and subsequently to the final polycondensation reactors. The final polycondensation reactor plays a crucial role in achieving the desired polymer chain length, thereby attaining the targeted properties of the Polycarbonate. Both the horizontal prepolycondensation II stage and the final reactor are equipped with a disc-ring agitator, ensuring significant surface area for efficient mass transfer and chemical reactions.
