What Is ASTM D3222 PVDF Molding Coating Material?
ASTM D3222 provides a classification system and specification requirements for polyvinylidene fluoride (PVDF) molding and coating materials. PVDF is a high-performance fluoropolymer known for its exceptional chemical resistance, thermal stability, UV resistance, and piezoelectric properties. Standardising its characterisation ensures consistent material quality for demanding industrial and electronic applications.
The standard classifies PVDF materials based on melt flow rate, tensile strength, elongation, and other performance properties, and defines test methods for verifying conformance. ASTM D3222 serves as a procurement and qualification tool, allowing users to specify PVDF grades based on their performance requirements and enabling suppliers to certify their materials against defined property ranges.

Our ASTM D3222 Testing Procedure
Specimen Preparation
PVDF specimens are molded or prepared per applicable ASTM procedures for each property test.
1Melt Flow Rate
MFR is determined per ASTM D1238 at the specified temperature and load.
2Tensile Testing
Tensile strength and elongation are measured per ASTM D638.
3Dielectric Testing
Dielectric constant and dissipation factor are measured per ASTM D150.

ASTM D3222 PVDF Molding Coating Material FAQs
It covers unmodified PVDF homopolymer materials used in molding, extrusion, and coating applications.
The standard applies to pellet and powder forms of virgin PVDF resin.
No, it applies only to virgin unmodified homopolymer PVDF, not reinforced, filled, or copolymer grades.
Typical properties include melting point, density, flow rate, tensile strength, and dielectric performance.
PVDF generally melts between 156°C and 180°C.
