Import Butyl Rubber Putty — Buy in Bulk from Supplier in China

The product is a single‑sided butyl tape supplied by Kamical Sealing Material Company in China. It consists of a self‑adhesive layer bonded to a butyl rubber core that is blended with poly‑isobutene. The tape is supplied in black, with the isolation paper carrier available in yellow or white, and is offered in widths from 1 cm to 10 cm and thicknesses from 1 mm to 10 mm. Shelf life is twelve months, while the service life can exceed twenty years under normal conditions.

Butyl rubber provides permanent flexibility and excellent resistance to UV radiation, chemicals, weathering and corrosion, which are typical advantages of sealing tapes in the construction sector. The material’s high tensile strength and elongation allow it to accommodate interface deformation without losing adhesion. Compared with standard silicone or acrylic tapes, butyl‑based products generally exhibit lower permeability to water vapour, making them a common choice for waterproofing. The tape is supplied on rolls packed in cartons measuring 40 cm × 40 cm × 18 cm.

Typical applications include roof and steel‑structure crack patching, waterproof sealing of pipe joints, fan lap joints, glass curtain walls, doors and windows. Contractors, building‑material distributors and industrial maintenance teams are the primary buyers. The product is shipped as non‑dangerous goods, with storage recommended below 35 °C and protection from direct sunlight and rain. Buyers should confirm packaging quantity per carton, Incoterms and payment terms directly with Kamical before placing an order.
