ASTM D1667 Flexible Cellular Materials Overview
ASTM D1667 is a standard specification that defines the requirements for flexible closed-cell cellular materials made primarily from poly(vinyl chloride) (PVC) or its copolymers. These materials are commonly manufactured in sheet, strip, molded, or shaped forms for industrial and commercial applications.
The standard outlines material properties, manufacturing considerations, and testing requirements to ensure consistent performance. It focuses on evaluating characteristics such as compression behavior, water absorption, and structural integrity of closed-cell foam materials used in insulation, sealing, and cushioning applications.

Frequently Asked Questions
ASTM D1667 is a specification that defines requirements and test methods for flexible closed-cell PVC foam materials, ensuring consistent performance, durability, and suitability for industrial applications such as insulation and sealing.
The standard covers flexible closed-cell cellular materials made primarily from poly(vinyl chloride) or its copolymers, commonly used in foam sheets, molded parts, and insulation products.
Properties such as compression deflection, compression set, water absorption, and structural integrity are evaluated to determine the performance and durability of flexible cellular materials.
Closed-cell structure refers to a foam where individual cells are sealed and not interconnected, providing better insulation, water resistance, and mechanical strength compared to open-cell materials.
It ensures standardized quality and performance of PVC foam materials, helping manufacturers and engineers select appropriate materials for applications requiring durability, insulation, and resistance to moisture and deformation.
