Mica is a naturallycurring from the silicate family, well-regarded for itsunique properties including thermal stability, dielectric strength, and its ability to be split into thin, flexible sheets. Due to these characteristics, mica is widely utilized across many industries—from electronics and automotive to construction and energy. At YILONG, we specialize in providing mica-based insulation products for high-performance applications where reliability under heat and voltage stress is crucial.
Mica’s Role in Industrial Insulation
YILONG offers a range of mica products—such as Mica tape, sheets, paper, and tubes—that are used in environments requiring superior thermal and electrical insulation. These products are essential for equipment operating under high voltage or extreme heat, offering long-term protection and stability where traditional materials may degrade.
Mica tape: Flexible and Fire-Resistant Insulation
Mica tape is a reinforced insulation material composed of natural mica bonded with high-performance resin. It is ideal for use in motors, transformers, cables, and other components requiring high dielectric strength, fire resistance, and thermal reliability.
Common applications include:
Electrical Motors & Transformers: Coil and winding insulation under high voltage.
Cables & Wiring: Provides reliable fire-resistant electrical insulation.
Heating Equipment: Used in furnaces and high-temperature machinery.
Fireproof Systems: Enhances flame protection in emergency circuits and infrastructure.
Mica sheets, Paper, and Tubes
Mica sheets
Manufactured by compressing mica into thin panels, Mica sheets offer excellent thermal and electrical insulation. They are chemically inert and stable at high temperatures, making them suitable for capacitors, panels, high-voltage circuits, and other critical equipment.
Mica paper
Mica paper is produced by layering fine mica particles into thin, flexible sheets. It is often coated for extra durability and is used in motors, transformers, and fire-resistant insulation applications that require lightweight but highly reliable materials.
Mica tubes
Mica tubes are made by rolling Mica paper or sheets into cylindrical forms. They provide excellent dielectric insulation and high heat resistance, commonly used to insulate cables, heating elements, and electrical conductors in high-stress environments.
Additional Industrial Applications of Mica
Automotive
Used in brake linings, gaskets, and other high-heat components due to its heat-resistant properties.
Electronics
Integrated into capacitors, resistors, and PCB components for stable insulation at elevated temperatures.
Construction & Engineering
Blended into wallboards and fireproof materials to improve structure and thermal insulation.
Paints & Coatings
Mica enhances durability and provides a pearlescent effect for surfaces exposed to outdoor environments.
Conclusion
Mica continues to be a critical mineral in modern industrial applications—particularly in insulation and high-temperature environments. Its outstanding properties make it an ideal choice for electrical safety, durability, and fire resistance. YILONG remains committed to delivering high-quality mica-based products for diverse applications, supporting industries with advanced materials tailored to the needs of safety, efficiency, and innovation.
In the vast world of materials engineering, few substances hold as much significance as resins. Among these, phenolic and Epoxy Resins stand out due to their versatile applications and remarkable properties. These two types of resins are the backbone of numerous industries, from construction and automotive to electronics and aerospace, where they play crucial roles in enhancing product performance and durability.
Polytetrafluoroethylene (PTFE) is a high-performance material widely recognized for its exceptional chemical resistance, low friction coefficient, and excellent electrical insulation. Due to these properties, PTFE sheets are extensively used across industries for gaskets, seals, linings, and insulation applications. At YILONG, we supply both molded and Skived PTFE Sheets, catering to diverse customer needs with consistent quality and performance.

Selecting the right Electrical Insulation material has a direct impact on system performance, safety, and service life. Understanding the properties and applications of various insulation materials helps engineers and manufacturers make informed decisions tailored to their specific needs.
Insulation sheets are multifunctional materials widely used across industries due to their excellent thermal, electrical, and acoustic insulation properties. With low thermal conductivity, high dielectric strength, and reliable sound absorption, they offer dependable solutions for energy efficiency, system safety, and noise control.
Yilong insulation materials (subsidiary of Shandong Sida Industry Co.,Ltd.) has built a strong reputation since its inception in 1966 as a state-owned factory in Zhucheng, Shandong. Through significant transformations—including a pioneering shift to a joint-stock cooperative system—it evolved into a modern corporation with a registered capital of ¥61.56 million, over 1,300 employees, and total assets around ¥320 million .
Today, thermosetting resins are typically produced in smaller volumes than thermoplastic resins and often play a supporting role in the materials industry. However, did you know that the first synthetic resin ever invented was not a thermoplastic, but a thermosetting resin called bakelite?
FR-4, the widely used epoxy glass cloth laminate, is well known for its excellent mechanical strength, flame resistance, and electrical insulation. While most people associate FR-4 with the typical green color seen in printed circuit boards (PCBs), FR-4 is actually available in several different colors, including yellow, white, black, and natural (light green or beige). But what do these colors really mean?
FR-4, G10 and G11 are all thermoset materials widely used in the electronics and electrical engineering industries for their properties and performance.
G-10 is a high-performance glass epoxy composite that has become indispensable across a wide range of industries due to its exceptional strength, durability, and resistance to environmental factors.
