In the mature track of the thermal insulation material market, the iteration of traditional categories has always centered on "performance adaptation" and "cost balance", and PVC foam insulation boards have become an enduring important choice by virtue of their unique core advantages. As a closed-cell rigid foam board based on polyvinyl chloride resin, the PVC core composed of independent internal bubbles is the key carrier of its performance. This core structure not only endows the board with smooth and dense surface characteristics but also establishes its core competitiveness in waterproofing and corrosion resistance. Relying on the structural advantages of the PVC core, it can be flexibly compounded with glass steel plates, thermoplastic plates and other materials to adapt to diverse scenario needs. In the fields of construction, pipeline insulation and packaging, PVC foam insulation boards, with the combination of "moderate cost + simple processing + reliable performance", show irreplaceable value especially in scenarios with clear requirements for waterproofing and corrosion resistance, and become a classic representative in the field of traditional thermal insulation materials that stably empowers industrial applications with core structures.

Application
Packaging & Shipping
To address product damage from violent shaking and collisions during long-distance transportation, we offer two protective solutions:
Standard protection: Securing products with iron frames, wooden pallets and other accessories to guarantee basic transportation safety.
Customized protection: Delivering tailored packaging based on your specific requirements, with 30% enhanced performance compared to the standard solution (e.g., specialized shock-absorbing materials, custom-fitted frames).
Core Features of PVC Foam Insulation Board
Balanced Thermal Insulation and Physical Properties
Moderate Thermal Insulation Performance With a thermal conductivity coefficient generally ranging from 0.035 to 0.045 W/(m·K), this material delivers reliable insulation for medium-to-low temperature scenarios (-10℃ to +60℃). It offers a highly balanced thermal performance that outperforms traditional rock wool (0.04–0.045 W/(m·K)), making it an efficient choice for standard climate control and insulation needs.
Closed-Cell Waterproof Structure Featuring a closed-cell rate of ≥ 90% and a water absorption rate of ≤ 2% (by volume), its insulation performance degrades very slowly even in humid environments. This robust moisture resistance allows it to be directly and safely applied to water-exposed areas such as bathrooms, basements, and other damp spaces without compromising its core functionality.
Weather Resistance and Chemical Stability
Environmental Durability The material maintains excellent structural integrity across an operating temperature range of -30℃ to +70℃. It is highly resistant to acid and alkali corrosion (stable within a pH range of 3–11) and is completely immune to mold and insect infestation. These traits make it an ideal, long-lasting solution for high-humidity coastal areas or light chemical industry environments.
Controllable Flame Retardancy Through the addition of specialized flame retardants, it can successfully meet the GB 8624 B1-grade flame-retardant standard (with an oxygen index ≥ 28). In the event of combustion, it produces no dripping and generates only a moderate amount of smoke, significantly enhancing overall fire safety.
Processing and Cost Advantages
Easy Processability Designed for rapid on-site construction, the material can be effortlessly sawn, planed, bonded, or even manually cut with a standard utility knife. Furthermore, its smooth surface readily accepts printing, laminating, or painting, allowing for strong decorative effects and seamless integration into various architectural designs.
Cost-Effectiveness Benefiting from low raw material prices, its production cost is highly competitive in the market. This outstanding cost performance makes it an exceptionally practical and economical choice for large-area applications where budgets are limited but reliable performance is still required.
