Import Adhesive Foam Tube — Buy in Bulk from Supplier in China

The Huzhou Sanhe Insulation Material Factory produces adhesive-backed foam tube in a density range from 20 kg/m³ to 200 kg/m³, available in diameters from 1/8 inch (3.175 mm) upward and wall thicknesses from 1/8 inch upward. The supplier states that lengths are produced to customer requirements, with packaging in plastic or carton. Colour options span the full range. The material carries property claims aligned with UL94 flammability classification, ASTM testing protocols, RoHS restricted substance compliance, and FDA food-contact suitability, though buyers should request current certificates for verification against specific standards and lot numbers.

The foam base material is unspecified beyond the generic term 'foam', which in industrial tubing contexts typically denotes closed-cell polyethylene (PE), polyvinyl chloride (PVC), nitrile rubber (NBR/PVC), or EPDM. Density variation from 20 kg/m³ to 200 kg/m³ suggests the supplier covers both soft, flexible insulation grades and higher-density structural or cushioning grades. The lower end (20-40 kg/m³) suits thermal insulation and air-sealing applications, while densities above 100 kg/m³ approach load-bearing foam. The self-adhesive backing is not specified as single-sided or double-sided, or whether it is a pressure-sensitive acrylic, rubber-based, or silicone adhesive. Standard practice in HVAC and refrigeration markets is a split-release-liner backed with synthetic rubber adhesive for metal and plastic surface bonding.

Buyers for this product include HVAC contractors, refrigeration equipment manufacturers, automotive trim suppliers, and plumbing insulation distributors. The UL94 claim indicates suitability for electrical and building applications where flame retardancy is mandated. The FDA mention opens food processing and pharmaceutical transport as potential end uses, though the specific regulation (21 CFR 177.1520 for olefin polymers, or broader food-contact compliance) must be verified. The adhesive formulation must be confirmed for service temperature range, as low-temperature application can cause adhesive embrittlement, while high-temperature exposure may degrade both the foam and the adhesive layer. The Zhejiang location offers export logistics through Ningbo or Shanghai ports.

Huzhou Sanhe Insulation Material Factory is located at No.1 Qianxi Road, Qianlong Development Zone, Huzhou 313216, Zhejiang Province, China. The supplier carries both Imported and Harbor trust tier designations on the platform, with a response rate of 0.00 percent and zero average response hours recorded at the time of extraction. The listing provides no information about factory establishment year, production floor area, number of employees, annual output capacity, export history, or client references. The address places the company in Huzhou, a city within Zhejiang's manufacturing belt with access to polymer material supply chains and Yangtze River Delta port infrastructure.

The supplier's product range centres on foam-based insulation and sealing products. No third-party audit results, quality management system certifications (ISO 9001, ISO 14001), or manufacturing license details appear in the extracted profile data. The dual trust tier annotation suggests some platform recognition, though the practical import of this is unclear. Buyers should conduct independent verification of the factory's existence and capabilities, including requesting business license registration, factory photographs, and samples with material safety data sheets before committing to volume orders.
