    Why Phenolic Caps?

    A phenol cap, like our 22-400 mm Black Phenolic Polycone Cap is a type of screw cap made from phenolic resin, a durable, heat-resistant, and chemically resistant material. These caps are commonly used in laboratory, pharmaceutical, and industrial applications because of their ability to withstand harsh chemicals, solvents, and high temperatures. They often come with different liners, such as polycone, PTFE, or rubber liners, to provide a secure seal and chemical compatibility.

    Why Buy Phenol Caps?

    1. Chemical Resistance – Ideal for storing aggressive chemicals, acids, and solvents.
    2. Heat Resistance – Can withstand high temperatures without degrading.
    3. Tight Seal – Often paired with specialized liners to prevent leaks and contamination.
    4. Durability – More robust than standard plastic caps, offering long-term performance.
    5. Laboratory & Industrial Use – Essential for lab-grade bottles, chemical storage, and pharmaceuticals.

    Why Purchase Polycone-Lined Caps?

    Polycone-lined caps are screw caps that have a polyethylene cone liner inside, designed to provide a secure, leak-proof, and air-tight seal. These caps are ideal for various applications, including chemical storage, pharmaceuticals, essential oils, and laboratory samples.

    Key Benefits of Polycone-Lined Caps:

    1. Superior Leak Prevention – The polycone liner conforms to the bottle’s neck, creating an exceptionally tight seal that prevents leaks and evaporation.
    2. Chemical Resistance – Compatible with a wide range of chemicals, including acids, solvents, and oils.
    3. Moisture & Oxygen Barrier – Helps prevent contamination by keeping moisture and air out.
    4. Prevents Product Degradation – Ideal for essential oils, perfumes, and volatile chemicals that require a stable environment.
    5. Reusable & Durable – Long-lasting liner that maintains integrity even with repeated use.
    6. Versatile Applications – Commonly used in labs, industrial settings, food and beverage packaging, and medical industries.

    About Continuous Thread Closures:

    The continuous thread (CT) cap is a plastic closure characterized by an uninterrupted spiraling thread. This type of closure is commonly used in the food, cosmetics, and personal care industries due to its ease of application and ability to create a secure seal.

They work best when utilized in conjunction with alcohols, ketones, oils, and food-related products.
