Phenolic is an industrial laminate with many applications and formulations based on its materials and specific properties. It has multiple uses in manufacturing electronics and fabricating parts. Atlas Fibre has a wide selection of phenolic materials available, including glass, canvas, linen, and paper. Learn more about the many uses and benefits of phenolic composites.
Phenolic material is a composite material produced when layers of fabric are coated with phenolic resin, heated, and put under high pressure. The phenolic resin consists of formaldehyde and phenol, which are bonded together into large molecules. Phenolic material is incredibly strong and durable but weighs much less than even the lightest metals. It’s often used in place of metal, where manufacturers need a lightweight solution.
Phenolic is often called the first plastic as Bakelite, the first commercial synthetic resin was made from phenolic. It’s a type of thermoset plastic, meaning that its shape is set once the material has been formed, heated, and cooled.
Three main types of phenolic composite exist — paper-based, cloth-based, and glass-based. Each option has unique properties and applications.
Paper-based phenolic consists of a resin binder and kraft paper base. It has good electrical insulating and mechanical properties and machines well. It typically costs less than other phenolic types.
Cloth-based phenolic is usually made from resin combined with either linen or cotton canvas. Each option has its benefits and drawbacks. Canvas phenolic often has more mechanical strength than linen, but linen machines more easily. Both canvas and linen phenolic can be designed to have more electrical properties.
Glass-based phenolic offers the best mechanical strength, heat resistance and electrical properties of all phenolic materials.
Atlas Fibre’s laminate materials are available in two shapes. They come in phenolic sheets, which can be cut to meet your specifications and also come in a range of thicknesses. They can also be wound into tubes of varying diameters.
Discover which phenolic composite is the right one for your project or application.
The applications for phenolic composite depend on the type of material. G-3, or glass phenolic, is best for applications that require low thermal expansion and high heat resistance. Since it’s corrosion-resistant, it’s often used to fabricate acid-resistant parts. Some uses for glass phenolic include:
Paper-based phenolic composite is better suited for applications that don’t require high heat resistance, such as:
Linen and canvas phenolic composite materials are ideal for use in the fabrication of:
