Phenolics are the result of polymerization between layers of paper, canvas, linen, or glass cloth impregnated with synthetic thermosetting resins. This laminated material is a popular alternative to acrylic because of its high resistance to flexing.
Paper Reinforced Phenolic
is a paper-based laminate with low phenolic resin content. Laminates are used when electrical insulation values are the most important feature. Paper Reinforced Phenolic is most commonly hot punched for a variety of low voltage electrical applications. Paper Reinforced Phenolic is also the most cost effective industrial laminate.
Cloth Reinforced Phenolic
comes in two different fabric options; canvas and linen. Cloth Reinforced Phenolic is used in applications that require greater mechanical strength than paper laminate. Canvas has better mechanical strength; however, linen has a finer texture and is easier to machine.
Glass Reinforced Phenolic
(Also known as G-10 Glass Epoxy) is a light green material that combines a woven glass fabric and an epoxy resin laminate that contains bromine. Glass Reinforced Phenolic provides consistent quality and good electrical properties under dry and humid conditions, as well as high flexural, impact, and bond strength at room temperatures. Due to a high mechanical strength, low water absorption and superior electrical characteristics, this product is suitable for a variety of structural, high humidity, and electrical insulation applications, which include terminal boards, lapping carriers, and disc and microelectronics polishing. It will withstand temperatures up to 284F and has a moisture absorption rate of .15%.
