Jamak’s in-house silicone compounding capabilities deliver the flexibility to create custom formulations engineered for the toughest environments. By keeping compounding Made in the USA, we provide supply chain security, tariff-free sourcing, and full traceability of materials for critical industries. With more than 100,000 square feet of ISO 14644-1 Class 8 cleanroom availability, compounds can be processed under tightly controlled conditions to protect purity and performance, which is essential for medical devices, aerospace components, and defense systems.

Formulation options include medical-grade silicones that meet FDA, USP Class VI, and ISO 10993 standards for biocompatibility, as well as specialty compounds such as fluorosilicone (FVMQ) for fuel resistance, conductive silicones for EMI/RFI shielding, and flame-rated materials for demanding environments. Each compound can be tuned for durometer, compression set, tear resistance, and elongation to meet exact performance requirements. Whether the need is high-strength medical tubing, fuel- and solvent-resistant aerospace seals, or conductive shielding gaskets, our compounding expertise ensures reliable, repeatable performance backed by thorough documentation and testing.
