VT70WH28 is a white FKM Type GF compound designed for FDA compliant and 3A sanitary sealing applications where enhanced chemical resistance is required. This 70 shore A material is ideal for O-rings and gaskets used in food processing, dairy, and pharmaceutical systems, offering strong performance in environments exposed to steam, acids, and aromatic hydrocarbons. It delivers excellent heat resistance and long-term stability while maintaining durability against cleaning cycles and aggressive media. With a service temperature range of -16°C to 225°C, VT70WH28 meets ASTM D2000 M2HK715 requirements and can be compared to Parker V1274-80 when evaluating equivalent sanitary FKM materials.
FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to chemicals, heat, and fuels is essential. GF-type FKM materials are formulated to provide improved resistance to steam, acids, and certain aggressive chemicals compared to standard grades. FDA compliant and 3A sanitary FKM compounds are commonly used in food, beverage, and pharmaceutical industries where both performance and regulatory compliance are critical. While highly versatile, FKM materials are generally not recommended for certain polar solvents or extreme steam conditions beyond their limits, making proper material selection essential.
