Delrin is a Homopolymer plastic that is known as POM-H.

Delrin has a high mechanical strength as well as, high fatigue endurance, creeper resistance and low moisture absorption. This material comes in Natural (white) and Black.

Naturally colored Delrin is FDA and USDA compliant.

One of its downfalls, is that it is not as chemically resistant as its Co-Polymer relation, Acetal. Additionally, during the process of producing Delrin, gasses fight their way to the surface causing pockets to form. This leads to a development of centerline porosity. With porosity comes weak spots. This can become problematic in a part that is designed for food processing and or medical applications since liquids can leak through the weak spots and create bacterial growth. Which is why Royal Custom Plastics only uses Delrin for applications such as gears, bearing, washers and rollers.

PHENOLIC

Under high heat and pressure, layers of cotton or linen canvas, glass cloth, or paper, are impregnated with thermoset resins to create Phenolic and its additional grades. These laminates are strong and durable while being lightweight and moisture resistant. Phenolics have high mechanical and isolating properties and cannot soften again. Phenolic laminates strength and stiffness leads to a high impact material.

Each grade of Phenolic has different strengths that offer an unlimited number of possibilities needed for the most difficult of applications. Below is the basic breakdown of the different grades of Phenolic and what they can offer.

GRADE C & CE

When the blend of medium weave cotton cloth fabric and Phenolic come together they create Phenolic C and Phenolic CE. This mixture provides a higher mechanical strength when compared to a paper grade. It also has a finer surface making it a superior machinable laminate. The toughness of this material is best suitable for applications requiring high impact strength. Grade CE is a great choice for electrical applications however, Grade C is not.

GRADE L & LE

A blend of Phenolic resin and fine weave cotton cloth fabric is what gives us Grades L & LE. Grade LE Phenolic is the same as grade L but with greater moisture retention which makes it the superior choice for electrical properties. The finely weaved cotton cloth base of both L and LE makes this Phenolic an even better machinable material than grades C & CE. When in need of more intricate details in your gears or pistons, Phenolic L & LE would be the best route.

GRADE X, XX & XXX

Paper mixed with Phenolic resin gives us Grades X, XX, and XXX. These are the most affordable grades in the Phenolic family. Each “X” represents a different level of dielectric strength and mechanical properties. Grade X has superb mechanical properties but is not suggested for applications where humidity is high and electrical properties are important. Grade XX is recommended for general electric insulations, while Grade XXX has superior electrical insulating strength and does well in high humidity, but its downfall is weaker mechanical properties.

GLASS PHENOLIC

G-7, G-10 and G-11 are made up of a mixture of either silicone or epoxy resin with glass cloth. G-7 is a glass-silicone laminate that has an excellent heat and arc resistance along with good electrical properties. G-7 is best used for electrical grade insulation, heating insulation and appliance insulation. G-10 and G-11 Phenolic has a mixture of epoxy resin and glass cloth. These laminates are known for their extremely high strengths and high dimensional stability over temperature, low water absorption, and superior electrical properties when both wet and dry. G-10 and G-11 are very hard to work with and usually require special tooling when machining. While G-10 is slightly stronger, G-11 can withstand higher temperatures and is a better insulator.
