Many people tend to confuse Rigid Mica Sheet with ordinary insulating paperboard, bakelite board and plastic sheet, yet their performance levels are vastly different. Rigid Mica Sh

In industrial manufacturing, power & electrical equipment, new energy devices and daily household appliances, the service life and safety of equipment rarely depend on eye-catching

SMC Insulation Sheet refers to Sheet Molding Compound, which is mainly composed of special yarn for SMC, unsaturated polyester resin and various fillers. With superior electrical p

There is a wide range of insulation boards available on the market, including plastic boards, paper boards, bakelite boards and fiberglass boards for various applications. Nevertheless, no single material can fully replace Mica Board. The fundamental reason lies in its unrivaled balanced comprehensive performance and adaptability to complex working conditions.

With balanced and comprehensive performance, Mica Board has broken the restrictions of single-industry application and been deeply applied in household appliances, traditional industry, power and electrical engineering, high-end new energy manufacturing and other fields, making it a universal all-around safety substrate.

We have shared full knowledge about GPO-3 insulation board in previous articles from YILONG. This article will focus on a widely concerned topic: simple identification methods to distinguish qualified finished GPO-3 insulation boards from inferior ones. Let’s take a closer look.

GPO-3 Insulation Sheet is a rigid sheet insulating material manufactured by impregnating non-alkali glass fiber mat with unsaturated polyester resin paste together with corresponding additives, followed by hot pressing. It refers to unsaturated polyester glass fiber mat sheet material for mechanical and electrical purposes. It delivers excellent electrical properties under high humidity, favorable mechanical performance at medium temperatures, inherent flame retardancy, as well as outstanding arc resistance and tracking resistance.

FR4 Sheet, also known as epoxy fiberglass sheet or flame retardant insulation board, is fabricated by impregnating fiberglass woven cloth with flame-retardant epoxy resin and hot-pressed under high temperature and pressure. It is widely utilized in high-end precision equipment that demands high safety and reliability standards.
