Product information
Our inflatable gaskets are widely used in Fluid Bed Dryers (FBDs), common in pharmaceutical and chemical processing, and in pharmaceutical granulation and drying processes where consistent airflow and strict contamination control are required. Makvin Polymer's inflatable silicone FBD gaskets prevent the powder leakage and sterilization failures common with traditional gaskets.
Key features

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.
