Does the SILICONE STAR/D pressure silicone hose require pressure derating above +100Â°C, and if so, by how much per Â°C?

Yes. For the SILICONE STAR/D pressure silicone hose, at operating temperatures above +100Â°C the maximum working pressure must be derated by 1% for each 1Â°C increase in temperature. The hoseâs stated operating range is -60Â°C to +180Â°C, and the specified pressure tables apply up to +100Â°C; beyond that, reduce the listed maximum working pressure by 1% per Â°C above +100Â°C.

Is the SILICONE STAR/D pressure silicone hose suitable for use with food/pharmaceutical applications per FDA, USP and EU standards?

Yes. SILICONE STAR/D pressure silicone hose is suitable for food and pharmaceutical applications: it meets FDA 21 CFR 177.2600, USP Class VI, European Pharmacopoeia 3.1.9, BfR XV A, Journal Officiel Brochure 1227 and CE Directive 1935/2004. Its extruded translucent silicone inner layer and platinum-enhanced manufacturing are appropriate for hygienic contact. Note operational limits: temperature range -60Â°C to +180Â°C, and above +100Â°C reduce maximum working pressure by 1% per Â°C.

Can SILICONE STAR/D pressure silicone hose be autoclaved or steam-sterilized repeatedly without degrading properties?

Yes. SILICONE STAR/D pressure silicone hose can be autoclaved or steam-sterilized repeatedly without significant degradation of its core material properties, provided normal silicone-use conditions are respected. Why: - Materials and certifications: The hose features a platinum-cured (platinum-enhanced) silicone inner and outer layer and complies with FDA 21 CFR 177.2600, USP Class VI, and European Pharmacopoeia 3.1.9, all of which indicate suitability for repeated sterilization cycles and biocompatible, medical-grade performance. - Temperature range: The specified operating range (-60Â°C to +180Â°C) comfortably covers typical steam/autoclave temperatures (121Â°Câ134Â°C). The hose is designed for such thermal exposure. - Mechanical design: Four layers of polyester braiding provide reinforcement to maintain pressure integrity during thermal cycling. Important considerations: - Pressure derating: At operating temperatures above +100Â°C, reduce maximum working pressure by 1% for each 1Â°C increase. For autoclave cycles at ~121Â°Câ134Â°C, apply this derating when the hose is pressurized during sterilization. - Chemical/contaminant exposure: Repeated cycles with aggressive chemicals or residues could affect long-term performance; rinse and follow cleaning recommendations. - Cycle limits: Although materials and approvals support repeated sterilization, cumulative effects depend on cycle frequency, pressure during sterilization, and mechanical stress. Periodic inspection for microcracks, loss of flexibility, discoloration, or braid damage is recommended. - Application-specific validation: For critical sterile processes, validate hose performance in your exact sterilization protocol (temperature, pressure, duration, and cycle count). Conclusion: SILICONE STAR/D pressure silicone hose is suitable for repeated autoclave/steam sterilization within its stated temperature limits, with required pressure derating above 100Â°C and routine inspection/validation for critical applications.
