GPO3 sheet is a very good performance of the fire resistant cables tape, because it was so widely used, so that the counterfeiters will be more on-site market, there are too many fish mixed with GPO-3 insulation materials, although all Close to the GPO-3 label, but the performance is indeed a world of difference. Good insulating material can be safe and efficient for us to use, you can fake and shoddy products but there are many security risks. Below the unsaturated polyester glass mat sheet manufacturers teach you to identify the true and false GPO-3.
Method 1, genuine GPO-3 are required through the US safety laboratory certification (UL certification), with independent and unique UL identification code. So when you buy this kind of insulating material GPO-3 must see if there is no UL identification code, or let the business to provide UL identification code.
Method 2, genuine GPO-3 its resistance to leakage index can reach 600V, you can test it, or let the business to provide indicators.
Method 3, authentic GPO-3 insulation material density is between 1.81-1.83, must be in accordance with national standards, the middle must be no filler, so be sure to see.

Different electrical equipment requirements for the performance of GPO3 sheet are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss. Low-voltage electrical appliances, such as mechanical strength, elongation at break, heat-resistant grade as the main requirements.
The macroscopic properties of fire resistant cables tape such as electrical properties, thermal properties, mechanical properties, chemical resistance, weather resistance, corrosion resistance and other properties are closely related to its chemical composition and molecular structure. Inorganic solid insulation material is mainly composed of silicon, boron and a variety of metal oxides, mainly to the ionic structure, the main features of high heat resistance, the working temperature is generally greater than 180 ℃, good stability, resistance to atmospheric aging, Chemical properties and long-term under the action of the electric field aging performance; but high brittleness, low impact strength, high pressure and low tensile strength; poor process. Organic materials are generally polymers with an average molecular weight between 104 and 106, and their heat resistance is usually lower than that of inorganic materials. Contains aromatic rings, heterocycles and silicon, titanium, fluorine and other elements of the material heat resistance is higher than the general line of chain polymer materials.
An important factor affecting the dielectric properties of unsaturated polyester glass mat sheet is the strength of the polar and the content of polar components. The dielectric constant and dielectric loss of the polar material are higher than those of the non-polar material, and the impurity ions are easily adsorbed to increase the conductivity and reduce the dielectric properties. Therefore, in the insulation material manufacturing process should pay attention to clean, to prevent pollution. Capacitors require a high dielectric constant to improve their specific properties.

In the electricity process, people note that the size of the cross-sectional area of the power cord material on the safe use of electricity have an impact, but often the use of vpi mica tape is not enough attention. Power lines are now more and more complex, walking under the wood floor, walls, partitions and damp underground or water are, if the insulation tape used improperly, will produce leakage, endangering personal safety or cause a fire. So how do you use insulating tape correctly?
Power cord connector is divided into "ten" word connection, "one" word connection, "Ding" word connection and so on. Joints should be wrapped around, smooth without thorns. Before the thread is disconnected, it should be wiped with a steel wire, and then wound around the mouth, and then swing around, the thread will be quickly in the connector at the break. If the joints in the dry place, should first use insulated black cloth wrapped two layers, and then wrapped plastic tape (also known as pvc adhesive tape) two layers, and then J-10 mica insulation tape stretched about 200% Finally wrapped two layers of plastic tape.
Because the direct use of plastic tape a lot of defects: plastic tape a long time easy to glue dislocation, plastic open, electrical load heavy, the joints heat, plastic tape easy to melt shrink; electrical connectors in the junction box with each other pressure, Easy to stamp the plastic tape, etc., these risks directly endanger personal safety, causing the line is moderate, causing a fire. The use of insulating black tape will not appear above, it has a certain strength, flexibility, can be tightly wrapped around the long-term, by the time and temperature and dry fixed type, will not fall off, and flame retardant. Moreover, wrapped with insulated vinyl tape and then wrapped with moisture, rust.
Of course, bakelite sheet suppliers is also defective, although it is waterproof but easy to break, so the last need to wrap two layers of plastic tape for the protective layer, connector and connector insulation self-adhesive tape non-stick, better performance.

Electronic and compressed laminated wood plastics is used in the field of electrical and electronic engineering plastics insulation materials, conductive plastics, pressure / thermoelectric plastic and its selection and product design and manufacturing technology. The amount of plastic consumed by the electrical and electronic industry accounts for the third largest total volume of plastics, second only to the packaging and construction industries. The following electronic components and connectors to introduce plastic as an insulating material in the electrical and electronic industry on a number of applications.
Electronic Component:
insulation material tube are generally connectors, coils, induction components as the center, including filters, oscillators, keys and other components. The integration of these components and the emergence of surface decoration technology (SMT), so that the added value of electronic products greatly improved.
Connector:
The connector can be manufactured using a variety of materials such as PA, PBT, PET, etc., where the cost of using PA-made connectors is low. For example, EPGC204, processing fluidity is good, can be used for the production of thin-walled parts. With the diversification of parts, the dimensional stability and heat resistance requirements higher, the choice of PBT materials, in the special requirements of the connector can be made of PC material. Of course, PPS and LCP reinforced plastics with better heat resistance are also ideal targets.

Epoxy resin in the application process often encounter the following situation:
mica cable tape pouring, potting, molding and other parts after curing or storage will produce cracks during the resulting waste. EP parts in the low temperature or hot and cold alternating when there will be cracks. The larger the part, the more the insert, the more prone to cracks. It is generally believed that this is due to the fact that the curing stress and the temperature stress are greater than the strength of the material. So as long as the strength of EP can be improved to avoid cracking. However, high-intensity EP is often only low impact toughness. Structural elements made of high strength EP (such as structural adhesives, advanced composites, etc.) are often brittle in use and are less stressful than acetate cloth tapes. Fracture surface was brittle fracture morphology. Known as low stress brittle fracture. EP cured products are highly crosslinked polymers with high brittleness.
For the toughening of epoxy resin, due to the rubber toughening epoxy resin system in the fracture process, the main structure and the structure of the microstructure of rubber, but also the two-phase interface and particle volume fraction has a certain relationship. The toughening rate is mainly determined by the toughness of the microparticles, the average network length of the matrix, and the interface bonding force and the chemical structure of the network chain itself.

How the insulation material is divided by grade
pe mica tape insulation and temperature are closely related. The higher the temperature, the worse the insulating properties of the insulating material. In order to ensure the insulation strength, each insulating material has an appropriate maximum allowable operating temperature, below this temperature, can be used for a long time safe, more than this temperature will quickly aging. According to the degree of heat resistance, the g10 fiberglass tube is divided into Y, A, E, B, F, H, C and other levels, the heat resistance level corresponding to the following:
