Product information
Makvin Polymer manufactures sponge silicone profiles for applications that require soft cushioning, compressibility, and lightweight sealing. Unlike solid profiles, sponge silicone has a closed-cell structure, making it an excellent choice for sealing against air, dust, and moisture while reducing vibration and noise. Available in cords, strips, gaskets, and custom sections, they deliver dependable performance in both indoor and outdoor environments.
Key features
- Resistant to moderate heat, ozone, and UV
- Cost-effective solution for general use

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.
