The global electronic materials market is currently undergoing a transformative phase, driven by the rapid expansion of the semiconductor, automotive electronics, and 5G telecommunication sectors. As a core component in the Surface Mount Technology (SMT) and semiconductor packaging process, functional tapes—often referred to as Co Rubber-integrated materials—have become indispensable. "Co Rubber" (Composite Rubber) adhesives are the secret behind the high-performance bonding and thermal stability of products like cover tapes and acetate cloth tapes.
As industry leaders, we recognize that the "Wholesale Co Rubber Factory" designation represents more than just manufacturing; it signifies a commitment to technical precision. Global factories are now shifting toward sustainable, halogen-free, and high-purity materials to comply with stringent environmental regulations like RoHS and REACH. This shift ensures that the materials used in smartphones, EVs, and medical devices are not only effective but safe for the long-term global ecosystem.
As chips get smaller, the precision of carrier tapes and cover tapes must increase. Our factory utilizes high-precision slitting and coating tech to ensure widths are accurate to within microns.
Static electricity is the enemy of modern electronics. The next generation of Co Rubber products features permanent anti-static layers that protect sensitive ICs during transport.
With the rise of power electronics in EVs, tapes must withstand continuous operating temperatures exceeding 150°C without losing adhesive integrity.
Jiangsu Yongjia Electronic Materials Co., Ltd. was registered and established in June 2007. After eighteen years of deep cultivation in the field of electronic materials, the company has developed into a comprehensive service provider of tape products with considerable influence in the industry. Located in the vibrant industrial environment of Nantong, the company covers an area of 16,000 square meters, with a building area of 9,000 square meters.
The company focuses on the core track of functional tapes for the electronic industry, primarily engaged in the R&D, manufacturing, sales, and after-sales service of a series of products, including heat-seal cover tapes, self-adhesive cover tapes, acetate cloth tapes, glass fiber tapes, and PET tapes.
Being based in Nantong allows us to tap into the world's most robust raw material supply chain. We procure high-grade resins and fibers at competitive rates, passing those savings to our wholesale partners.
Our facility houses state-of-the-art laboratories where we test peel strength, aging resistance, and dielectric properties to ensure every roll meets international standards.
Unlike standard distributors, we are a direct factory. We can customize adhesive formulations, tape thicknesses, and spool lengths to match your specific industrial machinery requirements.
When searching for a Wholesale Co Rubber Factory, procurement officers in Europe, North America, and Southeast Asia are increasingly focusing on Total Cost of Ownership (TCO). This involves not just the unit price, but the reliability of the tape in high-speed automated production lines. A tape snap or adhesive failure can halt an entire production line, costing thousands of dollars per hour.
Our export experience shows that German automotive manufacturers demand high-tensile glass fiber tapes for battery insulation, while Vietnamese and Indian electronics assembly plants seek cost-effective acetate cloth tapes for transformer insulation. We cater to these localized needs by providing localized technical support and flexible logistics solutions.
