Our founding board, a team of rubber and polymer experts, pioneered self-fusing tape technology in China and developed self-fusing tapes for the country's power and telecom sectors. We were the first to apply KCJ Series Insulating Tape in systems up to 220 kV and introduce KCBD Series Semi-Conducting Tape for 500 kV high-voltage applications.

Established Wuxi Kechuang Electric and Telecommunication Apparatus Co., Ltd. and expanded operations with production and business facilities across key locations in Wuxi, China.

We developed and launched Fibre Closure Sealing Mastic Strip (KCMFT) and Sealing Tapes (KCMFD), and Waterproof Mastics (KCTC-801 to KCJN-809 Series) specifically engineered to provide reliable protection for joints in local telephone networks, coaxial cables, and fiber optic communication systems.

Waterproof Insulating Tape (KCJ-80) and Armour Tape (KCA-88) were developed for wrap joint splicing, usable on their own or together with cold-shrink cable accessory kits, as well as for a wide range of other applications, offering superior cable sheath repair, protection, and durability.

Introduced Self-Fusing Fireproof Tape (KCZF-90), specifically designed for fire protection in power cable installations and other high-risk fire environments.

Launched a comprehensive range of Waterproof Mastics (KCTC-801 to KCJN-809), engineered for sealing feeder line joints in telecom base stations, power applications, and various industrial uses.

Shenzhen Cotran New Material Co., Ltd. was established to provide advanced waterproofing and insulation solutions for telecommunications, and proudly became the first domestic supplier of Waterproof Insulation Tapes (KCJ-80 to KCJ-84) to top-tier telecom companies ZTE and Huawei.

Engineered high-performance functional mastics tailored for heat shrink and cold shrink cable accessories kits, trusted by leading domestic and global brands, showcasing our commitment to quality and innovation.

Wuxi Kuncheng New Material Technology Co., Ltd. was established as part of a strategic brand upgrade, focusing on innovative solutions in electrical tape, cable protection, and advanced sealing polymers. Our products serve critical sectors including power generation, transmission and distribution, substations, telecom, mining, railways, and infrastructure development.

Introduced Non-Solidifying Moisture-Sealing Silicon Mastic (KCSI-70), tailored for insulation and waterproof sealing protection for sensors and electrical joints on high-speed rail, while also providing reliable sealing and filling function for irregularly shaped joints.

Shenzhen Cotran New Material Co., Ltd. became a publicly listed company, marking a key milestone in its development. In 2018, Wuxi Kuncheng became a Cotran subsidiary, further strengthening our strategic positioning and reinforcing our commitment to customer-focused innovation.

Introducing Fireproof Sheet, Non-Solidifying Fireproof Mastic, Fire and Waterproof Sealant, Cable Fireproof Coating, Fire and Explosion-Proof Wrap, and Heat Absorbing Fireproof Wrap, all designed to enhance fire safety and support the reliable operation of power grid systems.

Brought to market the Self-Curing Waterproof Insulating Pad (KCFB-68), ideal for insulation, waterproofing, and repair of bare overhead conductors, busbars, lead wire clamps, irregular joints, and other exposed metal areas. Also launched Silicone and EPDM Cold Shrink Tubes (KCTG-100 and KCTG-101), expanding our protection solutions.

Established Anhui Shinyn New Materials Co., Ltd. a subsidiary of Wuxi Kuncheng, launching a new business unit specializing in Passive Fireproof Products including sheets, mastics, wraps, sealants, and moisture sealing polymer materials.

Operating from a 19,000 m² facility and using only premium raw materials, we hold ISO 9001, ISO 45001, and ISO 14001 certifications. Our products comply with global standards including UL, CE, CSA, PSE, SGS, ASTM, RoHS, WEEE, and REACH, supporting a strong market presence and earning the trust of customers worldwide.
