Import Expanding Foam Tape For Window And Door Sealing — Buy in wholesale FOB from Supplier in China

The expanding foam tape for window and door sealing is a pre‑compressed polyurethane tape that expands slowly and evenly after installation. It is supplied as a fine‑cell foam with a pressure‑sensitive adhesive on one side, allowing quick attachment to substrates. The tape expands to fill gaps, creating a continuous barrier against rain, wind, UV radiation, sound, draft and dust. The supplier, Zhejiang Shanghe Plastic Rubber Material Co., Ltd, lists the product as a permanent‑elastic seal with long‑term life expectancy.

Polyurethane foam tapes of this type typically have a density around 30 kg m‑3 and an expansion ratio of 2‑3 times the original thickness, which is standard for construction sealing applications. The material can operate between - 20 °C and 80 °C, a temperature range common for building envelopes. Typical tensile strength is about 150 kPa, providing sufficient resistance to mechanical stress during movement of joints. The foam’s acoustic and thermal insulation properties are comparable to other industry‑grade expanding sealants.

The tape is used by contractors installing windows, doors, façade panels, pre‑cast concrete elements and insulated metal roofing, as well as by retrofit specialists sealing control joints and vapor barriers. Buyers usually request bulk rolls sized to match the length of the joint, and they confirm packaging details such as reel or flat sheet format with the supplier. Because the listing does not disclose minimum order quantity or lead time, interested parties should contact the supplier directly to negotiate terms. Payment and shipping conditions are arranged on a case‑by‑case basis according to the parties’ agreement.
