Sold out. The dielectric constant (Dk) of a plastic or dielectric or insulating material can be defined as the ratio of the charge stored in an insulating material placed between two metallic plates to the charge that can be stored when the insulating material is replaced by vacuum or air. Polyacetal or Polyoxymethylene (POM) is above all recognised for its hardness, specifically when compared to Nylon, which in other ways is a very similar material to POM. FR4 uses 8 layers glass fiber material. The main difference between NEMA Grades G10 and FR4 is that FR4 is a fire retardant grade of G10. These qualities make FR4 an ideal default substrate for quality PCB manufacturing processes. The main difference between NEMA Grades G10 and FR4 is that FR4 is a fire retardant grade of G10.

It has characteristics of high strength, excellent electrical properties and chemical resistance not only at room temperature but also under humid or moist conditions. As Acetal C and Acetal H are both essentially polyoxymethylene they share many of the same POM properties: - One of their most popular properties in the engineering plastics community is their ease of machining. G10/FR4 are widely used in the electronics field – primarily because water absorption is virtually nil, rendering it an excellent insulator. Latest China HS Code & tariff for polyoxymethylene-(pom) - Tariff & duty, regulations & restrictions, landed cost calculator, customs data for polyoxymethylene-(pom) … FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). Some of them include: Automotive; Electrical & electronic; Industrial ; Drug Delivery; The polymer serves as an alternative to metals due to its low friction and wear characteristics as well as its excellent balance of mechanical and chemical properties.
