Polycarbonate Additives from China Suppliers - High-Quality PC Modifiers from a Reliable Factory

Polycarbonate (PC) is a versatile polymer characterized by the presence of carbonate groups in its molecular structure. Depending on the ester group configuration, polycarbonate can be categorized into various types, including aliphatic, aromatic, and aliphatic-aromatic variations. However, due to their lower mechanical properties, aliphatic and aliphatic-aromatic polycarbonates are less suitable for engineering applications. In contrast, aromatic polycarbonate is the only type that has reached industrial production levels and is widely recognized for its exceptional growth as an engineering plastic among the five major varieties, Despite its advantages, polycarbonate is not inherently resistant to ultraviolet light, strong alkalis, or scratches, which can lead to discoloration and degradation over time when exposed to UV radiation. This necessitates the incorporation of modified additives to enhance its durability, As a leading supplier and factory of polycarbonate in China, we are committed to providing high-quality PC products that meet the rigorous requirements of various industries. Our expertise in manufacturing ensures that our polycarbonate solutions continue to advance and adapt, making us a reliable partner for your engineering plastic needs

    Product Details

    Product Description

    Polycarbonate (PC) is a polymer containing carbonate group in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. The low mechanical properties of aliphatic and aliphatic aromatic polycarbonate limit their application in engineering plastics. Only aromatic polycarbonate has been industrially produced. Due to the particularity of polycarbonate structure, PC has become the general engineering plastics with the fastest growth rate among the five engineering plastics.

    PC is not resistant to ultraviolet light, strong alkali, and scratch. It turns yellow with long-term exposure to ultraviolet. Therefore, the need for modified additives is essential.

    ⚠️

    Key Limitation: PC is not resistant to UV light, strong alkali, and scratching — turning yellow upon prolonged UV exposure. Modified additives are critical to maintaining performance and appearance.

    The company offers the following PC additives:

    💬 Frequently Asked Questions
    Q What is polycarbonate (PC) and why does it require additives?
    A Polycarbonate (PC) is a high-performance engineering polymer featuring carbonate groups in its molecular chain. While it offers excellent mechanical and optical properties, PC is inherently vulnerable to UV radiation, strong alkalis, and surface scratching. Additives such as UV absorbers are essential to protect PC from yellowing and degradation, extending the lifespan of PC-based products.
    Q Which types of polycarbonate are suitable for industrial engineering applications?
    A Only aromatic polycarbonate has been industrially produced for engineering plastics applications. Aliphatic and aliphatic-aromatic polycarbonates exhibit lower mechanical properties, which limits their practical use in demanding engineering environments.
    Q What are the main differences between YIHOO UV3030 and YIHOO UV3035?
    A YIHOO UV3030 (CAS: 178671-58-4, counter type: UVINUL 3030) is specifically designed for high-temperature polymer processing, making it ideal for PC, PET, and PES applications. YIHOO UV3035 (CAS: 5232-99-5, counter type: UVINUL 3035) is a broader-spectrum UV absorber used across plastics, paints, dyes, automobile glass, cosmetics, and sunscreen formulations.
    Q Which YIHOO UV additive is most suitable for both PC and PET applications?
    A YIHOO UV1577 (CAS: 147315-50-2, counter type: TINUVIN 1577) is specifically recommended as the most suitable UV additive for both PC and PET applications, offering targeted UV protection for these two widely used engineering polymers.
    Q Does the company offer polymer additives for applications beyond PC?
    A Yes. The company provides a comprehensive range of polymer additive solutions covering PA polymerization & modification, PU foaming, PVC polymerization & modification, TPU elastomers, low VOC automotive trim, textile finishing agents, coating additives, cosmetics additives, API, and specialty chemicals such as zeolite.
    Q How can I request a product inquiry or get more technical information?
    A You are welcome to contact the company directly for product inquiries, technical datasheets, or customized additive recommendations. The team is ready to assist with specific application requirements and provide expert guidance on the most suitable PC or polymer additive solutions for your needs.
