Import Aluminum Foil Tape — Buy in wholesale FOB from Supplier in China

Ronghaoyang Optoelectronics Co., Ltd. supplies aluminum foil tape manufactured from aluminum alloy with a minimum purity of 99.5% Al, positioned for electromagnetic shielding, thermal management, and sealing applications in electronics manufacturing. The tape employs a pressure-sensitive adhesive backing applied to corrosion-resistant aluminum foil, delivering heat reflection and moisture barrier functionality for industrial environments. This product serves as a consumable material for manufacturers of transformers, mobile phones, computers, PDAs, LCD monitors, laptops, and copiers where EMI shielding is critical.

The base material thickness for this product category typically ranges from 0.007mm to 0.075mm, with adhesive thickness between 0.015mm and 0.04mm depending on application requirements. Standard tape constructions use either ordinary pressure-sensitive acrylic adhesive for non-conductive bonding or conductive acrylic adhesive for electrical continuity applications. The aluminum substrate provides electrical signal shielding through its inherent conductivity, while magnetic shielding performance depends on the specific adhesive formulation employed. Tensile strength in comparable industrial grades typically falls between 4.5 and 4.8 kg per millimetre, with elongation at break of 7% to 10% minimum. Temperature resistance spans -10 degrees C to 120 degrees C for standard formulations, though buyers should confirm exact thermal performance with the supplier for their specific application.

Primary buyers include OEMs and contract manufacturers in consumer electronics, telecommunications equipment, and industrial control systems requiring compliant EMI/RFI shielding materials. The tape is convertible through die-cutting and slitting to customer-specified dimensions, with peel adhesion typically measured at 0.2 to 1.5 kgf per 25mm width in 180-degree reverse peel testing. Applications extend to grounding paths, static discharge management, and enclosure sealing where both electrical and environmental protection are needed. Importers should verify the specific adhesive system, conductivity requirements, and any necessary flame-retardant certifications with Ronghaoyang Optoelectronics before finalising specifications.

Ronghaoyang Optoelectronics Co., Ltd. is located at No. 50, Shengye Road, Dongguan City, Guangdong Province, China, postcode 523750, placing it within the Pearl River Delta manufacturing corridor. The supplier holds a harbor trust tier designation on the platform, with a recorded response rate of 0.00% and zero average response hours in the available data. Buyers should note that the current profile lacks verification of export licence status, factory audit records, or ISO certification details, and direct confirmation of operational capacity is advisable before committing to orders.

The company profile does not disclose year of establishment, registered capital, production floor area, or employee count, so claims about scale cannot be independently verified. No client references, export destinations, or case studies are present in the source material. The listing positions the supplier toward electronics manufacturing buyers seeking aluminum and copper foil shielding materials, with product knowledge focused on EMI applications rather than general industrial tape markets. Communication channels and sample policies are not specified in the available data.
