Overview & Material Characteristics
Our closed-cell NBR/PVC elastomeric rubber insulation is engineered to minimize thermal transfer, prevent condensation, and control energy loss in HVAC, refrigeration, plumbing, and industrial piping systems.
As the direct manufacturing source, we supply bulk rolls, sheets, and pre-formed tubes to global distributors, mechanical contractors, and OEM brands. Production runs are strictly regulated to maintain a consistent density range of 40 to 70 kg/m3 and dimensional stability, ensuring dependable field installation and long-term service life.
Core Technical Performance
Thermal Conductivity: 0.032 - 0.036 W/(m·K) at 0°C.
Closed-Cell Content: >95%, providing a uniform cellular matrix that limits convective heat transfer and keeps thermal performance stable over time.
Condensation is the primary driver of corrosion under insulation (CUI) and mold. Our integrated skin structure acts as a permanent vapor retarder without requiring secondary foil layers for standard indoor environments.
Water Vapor Diffusion Resistance (mu): >= 7,000 - 10,000
Water Absorption: <= 5% by volume after extended immersion.
Standard Grade: -50°C to +105°C
High-Temperature Grade: Formulations customized up to +150°C for specific industrial processing lines.
Formulated to slow flame propagation and suppress smoke generation, meeting major regional commercial building codes and environmental standards:
Ratings Available: B1 / Class 0 / EN 13501 / ASTM E84 (depending on regional project specifications).
Environmental Compliance: ISO9001 quality management certified, with formulations meeting REACH and RoHS requirements for global market entry.
The flexible elastomeric foam matrix inherently absorbs airborne sound transmission and mechanical vibration from pumps, chillers, and duct networks.

Factory Quality Control & Manufacturing Consistency
To eliminate batch variance in large-scale projects, our production facility implements strict quality protocols before any material is packed for export:
In-Line Monitoring
Automated extrusion lines maintain strict wall thickness and inner diameter tolerances.
Batch Testing
Random samples from every production shift undergo testing for density, thermal conductivity, tensile strength, and water absorption.
Traceability
Each shipment includes a Certificate of Analysis (COA) corresponding to the specific production lot.
OEM, Private Label & Export Services
We support international trade partners with flexible manufacturing and logistics solutions:
Customization Options
Custom wall thicknesses, inner diameters, roll lengths, self-adhesive backing, aluminum foil facings, and color-matched jackets.
Private Labeling
Branded carton design, customized polyethylene film packaging, barcode printing, and technical data sheets (TDS) featuring your company branding.
Export Documentation
Complete document support including Certificate of Origin (CO), Form E, Material Safety Data Sheets (MSDS), Packing Lists, and Commercial Invoices.
Logistics
Optimized container loading (combining tubes and sheets in mixed configurations) to maximize shipping volume.

FAQ
Q: What is the lead time for standard container orders?
A: Standard production cycles take 15 to 25 days depending on the volume and specific customization requirements.
Q: Can you supply insulation with self-adhesive backing?
A: Yes. We apply high-strength, weather-resistant acrylic adhesive protected by easy-release peel film on rubber sheets and split tubes.
Q: What is the minimum order quantity (MOQ) for custom colors or fire ratings?
A: MOQs vary based on raw material batches. Standard black B1 material has flexible startup thresholds, while specialized colors or unique fire ratings require specific minimum run volumes.
Q: How is the material packaged for long-distance ocean freight?
A: Tubes and sheets are packed in heavy-duty clear polyethylene bags and reinforced corrugated cartons to prevent compression damage and moisture entry during transit.
