Datasheets, material declarations (FDA / USP Class VI), RoHS/REACH statements and dimensional drawings for this product are issued on request with your quotation.
Request documentationPlatinum-cured silicone is addition-cured — odourless, low in extractables and preferred for medical, pharmaceutical and high-purity food contact. Peroxide-cured silicone is a robust, cost-effective choice for industrial and non-critical transfer. We supply both and will advise the right grade for your process.
Yes. Most items are produced to your drawing — bore/OD, wall, length, cross-section, durometer and colour. Send dimensions with your quote request.
Depending on the grade selected: FDA 21 CFR 177.2600, USP Class VI, ISO 10993, EU 1935/2004 food-contact, RoHS and REACH statements, plus batch material certificates and dimensional reports.
Sampling quantities are available for evaluation. Production MOQ depends on the profile/tool; we confirm it with the quotation.
Stocked lines ship within a few working days. Custom extrusions and moulded parts are typically confirmed per order after drawing sign-off.
