Insulation Sheet

High Density Polyethylene Sheets

High Density Polyethylene Sheets. Chinese name: Polyethylene plate. PE sheet is a high crystallinity, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section.

PE sheet product features:
1. The wear resistance of high molecular weight polyethylene board is the first in plastics, and the higher the molecular weight, the higher the wear resistance and impact resistance of the material;
2. The impact strength of ultra-high molecular polyethylene sheets is the highest value among existing plastics, and there is still a relatively high impact strength even at -70 ° C;
3. Self-lubricating;
4. Ultra-high molecular weight polyethylene has extremely low water absorption. Therefore, its physical and mechanical properties are independent of the humidity factor in the operating conditions used;
5. Ultra-high molecular weight polyethylene is chemically stable, and can resist corrosion of various corrosive media and organic solvents such as acid, alkali and salt at a certain temperature and concentration range;
6. Ultra-high molecular weight polyethylene is odorless, non-toxic, odorless, non-corrosive, physiologically circulatory and physiologically adaptable. read more

SMC insulation board

ZTELEC successfully developed the SMC insulation board of 1M×2M specification (thickness 3-28mm) according to the requirements of “SMC unsaturated polyester insulation separator applied to high voltage electrical switch instead of 3204 epoxy resin board” proposed by the product conference. The arc resistance and hygroscopicity are far better than the epoxy insulation board, which greatly enhances the insulation of the high voltage cabinet, ensuring the safety and reliability of the high voltage cabinet.
SMC insulation board product characteristics: high mechanical strength, flame retardancy, arc resistance, dielectric strength and high withstand voltage; low water absorption, dimensional stability, small warpage and so on. read more

FR-4 insulation boards

FR-4 is a code name for a flame resistant material. The resin material must be self-extinguishing after being burned. FR-4 is a commonly used insulating glass fiber board. Unlike ordinary insulating sheets, it can be flame retardant. In addition to good flame retardant properties, its mechanical strength and voltage resistance are also very good. It still has high mechanical strength at normal temperature of 130 ° C, good electrical properties in dry and wet state, flame retardant, used in electrical and electronic applications. Insulation structural components such as the industry. The raw materials for the production of FR-4 insulation board are epoxy resin, glass fiber reinforced cloth, and flame retardant. read more
