About Chengrun Tape

Chengrun Tape is the adhesive tape division of Dongguan Chengrun Insulation Materials Co., Ltd., a manufacturer of insulation materials with more than two decades of production experience. From a 10,000 m² plant in Dongguan, Guangdong, we coat, slit and convert adhesive tapes for the wiring harness, new-energy, appliance and electrical industries - with a daily output of 100,000 metres across nine production lines.
More than 300 companies worldwide use our tapes and insulation materials, including automotive and new-energy supply chains in China. We hold UL and CSA recognition for our insulation constructions and run an ISO 9001 and IATF 16949 quality system, so the tape that arrives on your line is the tape that was qualified on our pilot line.
In-house Coating & Slitting
Base material, adhesive formulation, coating and converting under one roof - tolerances stay under our control from master roll to finished log.
Certified Materials
UL and CSA recognised constructions, RoHS 2.0 and REACH compliant, with batch-level test reports available on request.
Automotive-grade Quality
ISO 9001 and IATF 16949 quality system, including low-VOC and noise-damping grades for vehicle interiors and enclosed electrical equipment.
Custom Converting
Width, length, thickness, core size and packaging to your drawing - slitting and die-cutting from sample to mass production without changing the construction.
Application Areas
Automotive Wiring Harness
Harness wrapping for engine compartments, doors and under-dash runs, where abrasion, temperature and noise damping all matter.
New-Energy Battery Packs
Insulation, fixing and edge protection inside battery packs, using high-temperature and flame-retardant grades.
Home Appliances & Motors
Coil, motor and lead-wire insulation and bundling for white goods and small appliances.
Transformers & Power Supplies
Layer and end-turn insulation, core strapping and lead dressing in transformers, inductors and switching power supplies.

Technical Advantages
One Supplier, Whole Temperature Range
From general-purpose PVC tape to PTFE tape rated -70 C to 260 C, you can standardise harness and insulation tapes with a single manufacturer.
Compliance You Can Document
UL and CSA recognised constructions, RoHS 2.0 and REACH compliance, plus low-VOC grades for enclosed spaces - with test reports issued per batch.
Stable Adhesion, Clean Removal
Controlled adhesive coating weight gives repeatable peel strength and residue-free removal, which means fewer reworks on the harness board.

Why Buy Tapes From Chengrun
Source Manufacturer, Not a Trader
Coating, slitting and converting all happen in our own 10,000 m² plant in Dongguan, so you are dealing with the factory that actually makes the tape.
Pilot Run to Mass Production
Sampling and pilot batches scale up to container volumes without changing the base material, the adhesive or the coating weight.
Automotive Supply-Chain References
Our insulation materials are used by automotive, appliance and new-energy customers in China, including major OEM supply chains.
Engineer-to-Engineer Support
Send us your application, operating temperature and VOC requirements - our engineers recommend a construction and back the recommendation with test data.
Global Supply
300+ Customers Worldwide
Tapes and insulation materials supplied to more than 300 companies across Asia, Europe, North America and South America.
Export Documentation
Commercial invoice, packing list, SDS and test reports are issued with every shipment, so customs clearance does not hold your line.
One Thread From Sample to Shipment
English-speaking sales engineers handle your RFQ, samples, order follow-up and after-sales requests in a single conversation.
