BOPET Black Film For Electronic Insulation

Jincheng has developed high-quality China BOPET Black Film for electronic insulation, which boasts excellent mechanical and electrical properties. The measured tensile strength is ≥ 150 MPa. The substrate has high stiffness, resistance to bending, deformation, fatigue, and is not prone to cracking or deformation even when repeatedly folded, compressed, or pressed over a long period.

Based on the modified polyester insulation formula, it possesses excellent high-voltage insulation and isolation protection capabilities, making it the core material for industrial electrical isolation. The entire series is equipped with standardized double-sided differential corona treatment. The inner corona surface has a 52-54 dynes guaranteeing the adhesion of printing, back adhesive, and composite bonding, while the non-corona surface has a 42-46 dynes for a smooth and flat surface, suitable for fully automatic die-cutting, lamination, and film coating production lines.

It can be widely used in electronic insulation pads, automotive interior shading, photovoltaic component isolation, industrial tape substrates, high-end black packaging inner linings, and is paired with a five-level standardized packaging scheme, suitable for domestic industrial mass production and cross-border export delivery standards of high-end industrial materials.

FAQ

Q1: How should H01 Bright Black and H05 Matte Black be selected?

For appearance decoration, gift box lining, black nameplates, and appearance labels, H01 Bright Black is preferred, as it has high gloss and fine texture; for electronic shading, vehicle interiors, precision instruments, and anti-glare industrial scenarios, H05 Matte Black is preferred, as it eliminates reflection interference and is suitable for the usage conditions of precision equipment.

Q2: This BOPET Black Film for Electronic Insulation is a coated film or a full-color film? Will it fade or lose powder?

This product is a primary motherbatch full-color co-extruded film, without surface sprayed coating. The overall black penetrates the base material. Normal die-cutting, bending, and friction will not cause fading, powder loss, or delamination. Its performance stability is far superior to ordinary coated black PET films.

Q3: Does it truly achieve complete shading with no any light transmission?

Yes. Each batch of products undergoes light transmission testing. The shading rate is 100%, the light transmission rate is 0%, there are no pinholes, no thin spots, and no local light leakage. It meets the high requirements of scenarios such as avoiding light, precise optical shading, and sealing isolation for high-end equipment.

Q4: Can it be used for high-voltage electrical insulation and photovoltaic component isolation?

It is fully compatible. The product has excellent high-voltage insulation performance and weather resistance isolation ability. It has a stable structure, is non-conductive, and resistant to breakdown. It is widely used in electronic insulation pads, circuit isolation, photovoltaic component sealing protection, and is a specialized base material for industrial insulation.

Q5: Is the film suitable for high-speed die-cutting processing?

It is very suitable. It has high tensile strength, good stiffness, and is not prone to deformation. The die-cutting and stamping edges are flat, without cracking, and without stretching. It is suitable for fully automatic high-speed die-cutting, lamination, and rewinding lines, and is suitable for large-scale industrial component production.

Q6: Which packaging method is recommended for export orders?

For domestic regular turnover, simple packaging and horizontal and vertical pallets are selected; for cross-border shipping, long-distance foreign trade orders, priority is given to using suspended pallets and export-specific moisture-proof and reinforcement pallets. They effectively prevent moisture, pressure, and scratches, ensuring the high-precision quality of industrial films.
