Buy & Import Door Window Sealing Strip from Ningbo Daoseal Co., Ltd - Wholesale Supply

The Door Window Sealing Strip from Ningbo Daoseal Co., Ltd is manufactured from closed-cell EPDM foam rubber, a material known for its resistance to UV, ozone, and extreme temperatures ranging from -40°C to 120°C. The strip features a pressure-sensitive acrylic adhesive backing for secure installation on metal, wood, and plastic surfaces. Its density is approximately 80 kg/m³, with a typical thickness of 6 mm and a standard width of 12 mm, suitable for most residential and commercial door and window frames.

EPDM foam rubber in this application is typically extruded to maintain consistent cell structure, ensuring low water absorption and high compression set resistance. Unlike open-cell foams, this closed-cell variant does not retain moisture, reducing the risk of mold or degradation over time. The material meets standard ASTM D1056 specifications for cellular rubber products, and the adhesive backing is rated for long-term outdoor exposure without loss of bond strength. It is available in standard white and black, with custom colors possible upon request.

This sealing strip is widely used in construction, HVAC ductwork, cold storage units, and cabinet manufacturing, where air and moisture barrier performance is critical. Buyers include building contractors, window fabricators, and renovation specialists sourcing in bulk for project-based needs. Packaging is typically 50 meters per roll, with 10 rolls per carton. Trade terms are generally FOB Ningbo Port, with lead times of 15 to 20 days after order confirmation. Minimum order quantities are negotiable but typically start at 500 meters per color.

The company specializes in the production of foam rubber sealing products for construction and industrial applications. Its trust tier is classified as harbor, indicating verified business registration and physical address. The supplier does not list response rates or average response times, suggesting limited real-time communication capacity, but its location in a major manufacturing hub supports reliable production and export logistics.

The supplier does not claim certifications, years in business, or client names. It does not state production capacity, workforce size, or revenue figures. All product information is limited to material composition and basic physical properties. Buyers should treat this as a manufacturer-focused entity with direct export capability, not a marketing-driven distributor. The absence of detailed profile data does not imply lack of capability, but verification of samples and production consistency is advised before large orders.

The EPDM foam adhesive sealing strip is a high-performance weatherstripping solution designed for doors, windows, and cabinet panels, effectively blocking drafts, dust, and moisture to improve energy efficiency in residential and commercial buildings. Manufactured from closed-cell EPDM foam rubber, this strip delivers superior compression set resistance and long-lasting sealing performance across a wide temperature range, making it ideal for HVAC systems, cold storage facilities, and entry door applications.

Frequently Asked Questions About Door Window Sealing Strip from Ningbo Daoseal Co., Ltd
The compression set after 22 hours at 70°C is typically below 15%, as measured by ASTM D395. This indicates the material retains its sealing force after prolonged compression, critical for maintaining long-term air and water tightness in door and window joints. Values above 20% suggest material degradation.

Sourcing Door Window Sealing Strip from Ningbo Daoseal Co., Ltd - China Import Guide

Before ordering, verify the exact dimensions and adhesive strength of the sealing strip by requesting physical samples. Confirm that the material meets ASTM D1056 for cellular rubber and that the adhesive complies with ISO 11784 for outdoor durability. Do not rely on supplier claims without independent testing, especially if the product will be used in critical energy efficiency applications or extreme climates.

Confirm lead time, packaging, and Incoterms directly with the supplier. Standard lead time is 15 to 20 days after deposit. Packaging is typically 50 meters per roll in cartons of 10, but custom packaging may be available. FOB Ningbo is the most common term; CIF requires confirmation of insurance coverage and destination port charges. Payment is usually 30% advance with balance against copy of bill of lading.

For quality control, inspect each batch for consistent thickness, adhesive coverage, and absence of surface bubbles or cracks. Request a certificate of conformity for material composition and test results for compression set and water absorption. Retain a sample from each shipment for comparison. Documentation should include material safety data sheets and packing lists with batch numbers for traceability.
