Import Construction Method Of Panzhu Waterproof Tape — Buy in Bulk from Supplier in China

The Construction Method Of Panzhu Waterproof Tape is a pressure‑sensitive butyl rubber strip produced by Fan Fei(Beijing) Energy‑Saving Technology Co., Ltd. The tape uses Isobutylene‑Isoprene Rubber (IIR) whose air transmittance is only one‑seventh that of natural rubber and whose vapor transmittance is one‑two‑hundredth of natural rubber. Its inherent chemical and thermal stability give it excellent air‑tight and water‑tight performance, making it suitable for sealing joints in building envelopes. The supplier notes that the material can endure temperatures from - 40 °C up to 120 °C and has an inert composition that can last up to fifty years in service.

Butyl rubber tape is commonly supplied in thicknesses around 1.2 mm, a figure that industry practice regards as typical for waterproof flashing applications. Typical tensile strength for IIR tape lies near 5 MPa and adhesion strength around 1.5 N per 25 mm, values that meet most construction standards. Standard weatherability tests show that similar tapes retain flexibility after repeated freeze‑thaw cycles, and the material’s resistance to UV exposure is recognised as a standard requirement for exterior use. These typical parameters complement the supplier’s claim of a service life of fifty years, indicating a product that aligns with long‑term durability expectations.

The tape is primarily used by contractors and facility‑maintenance teams to seal roof penetrations, balcony joints, and reflective‑cladding connections where both water tightness and air tightness are critical. Its pressure‑sensitive backing allows rapid installation with rollers, reducing labour time on large projects. Fan Fei does not disclose minimum order quantities, unit pricing, or exact lead times, so prospective buyers should request those details directly from the supplier before placing an order.

Fan Fei(Beijing) Energy‑Saving Technology Co., Ltd. is headquartered in Shenyang, Liaoning Province, China, as indicated by the listed address in the Huaqiang Community of Shenbei District. The company holds a “harbor” trust tier on the platform, although its response rate is currently recorded as 0 % and average response time is 0 hours, signalling that buyers should verify communication reliability before committing to large orders.

The supplier’s profile does not provide additional corporate history, employee count, or export certifications, and it does not state any specific quality management systems. Buyers are encouraged to request copies of any relevant certificates, such as ISO 9001 or product‑specific test reports, to confirm compliance with their project specifications.
