A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official fumed silicone rubber page describes HTV compounds reinforced with fumed silica for extrusion and moulding: WJ general transparent grades for tubes, profiles and wire, and YH medical grades for transparent medical consumables, listing models such as WJ-50-1CR (Shore A 50); the About page on the same domain states it was founded in 2004 and develops and produces silicone materials with annual output of 30,000 tonnes. Physical properties and medical compliance must be checked per model datasheet.

Fumed silicone rubber is used in applications requiring durable sealing, gasketing, and electrical insulation, especially in extreme temperatures and harsh environments.
Fumed silica creates a reinforcing network that enhances tensile strength, tear resistance, and compression set, while maintaining flexibility and thermal stability.
The typical continuous operating temperature range is -60°C to +200°C, with short-term exposure up to +250°C, but always verify with the manufacturer.
Common standards include ISO 7619-1 for hardness, ISO 37 for tensile and elongation, ISO 34-1 for tear strength, and IEC 60243-1 for dielectric strength. Confirm applicable standards with the supplier.
