Decoding the complexity of modern insulation materials in the age of high-frequency electronics.
The global market for Wholesale Insulation Materials is currently undergoing a radical transformation. As industries transition towards 5G telecommunications, electric vehicles (EVs), and advanced semiconductor manufacturing, the demand for high-performance functional tapes has surged exponentially. Traditional insulation is no longer sufficient; today's electronic environments require materials that offer a trifecta of thermal stability, electromagnetic shielding, and precise mechanical protection.
As components get smaller, cover tapes and insulation layers must be thinner yet more robust. Our R&D focuses on ultra-thin PET and Acetate solutions that fit the tightest tolerances in chip packaging.
Global regulations (like UL, RoHS, and REACH) are tightening. Flame-retardant properties in acetate cloth tapes are now a baseline requirement for international procurement in the automotive and home appliance sectors.
Automation in SMD (Surface Mount Device) assembly lines requires cover tapes with consistent peel strength and anti-static properties to prevent "pop-out" issues during high-speed pick-and-place operations.
Registered and established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has spent over 18 years deeply cultivating the electronic materials sector. We have evolved into a comprehensive service provider with a significant global footprint.
Located in Nantong's vibrant industrial hub, our facility spans 16,000 square meters with a 9,000 square meter state-of-the-art production workshop. Our infrastructure includes specialized R&D laboratories designed for the next generation of tape technology.

Engineered for excellence, tested for reliability.
Our acetate cloth tapes are crafted from high-quality acetate fiber and coated with pressure-sensitive adhesives. They offer excellent insulation, high temperature resistance, and are widely used for wire harness wrapping and transformer insulation.
Critical for semiconductor packaging, our heat-seal and self-adhesive cover tapes ensure that components remain securely in carrier tapes until the point of assembly.
From Glass Fiber tapes for heavy-duty reinforcement to PET tapes for electrical protection, our portfolio covers the full spectrum of industrial needs.
Our products serve as the "invisible shield" across diverse high-tech sectors.
Being based in Nantong, Jiangsu, we are at the heart of the world's most dense electronic materials ecosystem. This allows us to source raw materials efficiently and pass those cost savings directly to our Wholesale Insulation Materials partners.
Unlike massive conglomerates, our 100+ team is optimized for speed. We can develop customized tape thicknesses or adhesive strengths in weeks, not months, helping you meet specific local project requirements.
As an ISO-certified facility, every roll of tape undergoes rigorous testing for peel force, thermal resistance, and dielectric strength. Our commitment to quality has enabled us to become a key player in the "domestic substitution" of high-end semiconductor materials.
