Key Features of Our Phenolic

  • Wide Range of NEMA Grades: Paper grade phenolics (X, XX, XXX) and cotton grade phenolics (C, CE, L, LE) are each designed for specific mechanical and electrical performance needs.

  • Exceptional Electrical Insulation: Phenolics are ideal for electrical applications due to their low conductivity and high dielectric strength, making them reliable insulators in high-voltage environments.

    Shengquan are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

  • High Mechanical Strength and Dimensional Stability: Cotton-based phenolic grades offer excellent load-bearing capabilities, making them suitable for structural components and high-stress industrial applications.

  • Thermal and Moisture Resistance: As a thermoset plastic, phenolic resists heat and humidity without warping or degrading, providing reliable performance in demanding environments.

  • Easy to Machine and Fabricate: Phenolic materials can be easily cut, drilled, milled, or turned using conventional tools, allowing for custom fabrication and precise part creation.

  • Flame Retardant Options Available: Certain grades of phenolic are inherently flame resistant, making them a safe choice for applications where fire performance is a key requirement.

Benefits of Phenolic

Phenolic delivers reliable performance in high-stress environments with excellent resistance to solvents, oils, and chemicals. It offers strong electrical insulation, thermal resistance, and low moisture absorption for long-lasting durability. As a cost-effective alternative to metals, phenolic is ideal for a wide range of industrial applications. Contact Piedmont Plastics today to find the right phenolic solution for your project!

Frequently Asked Questions About Phenolic

When selecting the right industrial thermoset materials, it’s important to understand the unique properties and advantages that phenolic offers. To help you make the best choice for your project, we’ve answered some of the most common questions about industrial phenolics, including their grades, performance, and applications. Explore the FAQs below to learn more about how phenolic materials can meet your specific needs.

Phenolic material is made by layering paper, cotton fabric, or other substrates with phenolic resin, then curing it under heat and pressure to create a strong, rigid thermoset plastic. The result is a durable material known for its excellent electrical insulation, mechanical strength, and chemical resistance.

Paper grade phenolics (NEMA X, XX, XXX) offer excellent electrical insulation and are ideal for light mechanical uses, while cotton grade phenolics (NEMA C, CE, L, LE) provide greater mechanical strength, impact resistance, and better wear performance for demanding structural applications.

Yes, phenolic sheets can be easily machined using standard woodworking or metalworking tools. They can be cut, drilled, milled, or turned to create custom components with tight tolerances for industrial and electrical applications. Piedmont Plastics can also cut your material to size.

Yes, phenolic is an excellent electrical insulator. It offers high dielectric strength, low conductivity, and reliable performance in high-voltage and high-temperature environments, making it ideal for electrical panels, switchgear, and insulating components.

Yes, phenolic is considered an industrial laminate, but not all industrial laminates are phenolics. While phenolic laminates are among the most common, industrial laminates can also be made with other resins such as epoxy, melamine, silicone, or polyester, depending on the application. Each type offers different performance characteristics like higher heat resistance, better chemical resistance, or enhanced electrical properties.
