Solvay Tecnoflon VPL 45730 FKM Elastomer – Frequently Asked Questions (FAQ)

Q1: What distinguishes Tecnoflon VPL 45730 from other FKM elastomers in Solvay’s portfolio?

A: Tecnoflon VPL 45730 is a peroxide-curable, low-viscosity fluoroelastomer designed for high-temperature and aggressive chemical environments. Its VPL (Very Low viscosity, Peroxide-curable) architecture enables excellent processability in demanding molding operations—especially for thin-walled or highly filled compounds—while maintaining strong resistance to acids, fuels, oils, and polar solvents.

Q2: Is Tecnoflon VPL 45730 suitable for applications requiring FDA compliance or food-contact approval?

A: Tecnoflon VPL 45730 is not pre-certified for food-contact use under FDA 21 CFR or EU regulations. However, it may be formulated into compliant compounds when combined with appropriate FDA-listed curatives and processing aids—and validated through full formulation testing. End-use compliance must be confirmed by the compounder or end-user based on final product testing and regulatory requirements.

Q3: What types of peroxide systems are recommended for curing Tecnoflon VPL 45730?

A: This grade is optimized for peroxide cure systems, typically using bisphenol-free organic peroxides such as dicumyl peroxide or 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. Co-agents like triallyl isocyanurate (TAIC) or trimethylolpropane triacrylate (TMPTA) are commonly employed to enhance crosslink density and thermal stability. Optimal selection depends on the specific compound formulation and performance targets.

Q4: How does Tecnoflon VPL 45730 perform in dynamic sealing applications at elevated temperatures?

A: Thanks to its high fluorine content and stable carbon–fluorine backbone, Tecnoflon VPL 45730 delivers outstanding retention of elasticity and compression set resistance at continuous service temperatures up to 200 °C, making it well-suited for dynamic seals in automotive, aerospace, and industrial equipment where long-term reliability under thermal and mechanical stress is critical.
