For custom formulations, we work closely with customers to test and validate specific performance criteria, ensuring each silicone compound meets your exact functional requirements. This process guarantees optimal performance, consistency, and long-term reliability across diverse industrial, medical, and consumer applications.
Custom Formulation Process
1- Define Your Requirements
Before we develop your custom silicone formulation, it’s essential to provide a few key details. This ensures the sample we create matches your specifications perfectly and allows us to provide accurate pricing for your project. Use the options below as a guide.
Gather all required information before requesting a sample to streamline the process.
2- Technical Review
Once you submit your project details, our technical team evaluates your requirements to ensure the custom silicone formulation is feasible and meets performance expectations. This step allows us to select the optimal formulation, determine the appropriate processing method, and identify any necessary adjustments before producing your sample.
After the technical review, you’ll receive confirmation and any suggestions, ensuring the sample we produce is perfectly aligned with your project needs.
3- Sample Development & Testing
After your formulation is approved through technical review, our development team prepares a small-batch silicone compound for sampling and validation. Each sample is manufactured under controlled conditions, rigorously tested for mechanical and chemical performance, and supplied for your evaluation to ensure it meets your exact requirements.
After you evaluate the sample, feedback is reviewed with our technical team. If performance meets expectations, we proceed to pricing and full-scale production.
4- Pricing, Scale-Up, and Production
After your sample is approved, we provide a detailed quotation and scale the formulation for production. Every batch follows the same controlled process and quality standards, ensuring consistent performance from pilot quantities to full-scale industrial production.
Once your production order is confirmed, our team coordinates logistics and delivery timelines. Each batch includes traceable documentation and quality verification reports.

Applications
Quality Control & Laboratory Testing
At Wire Iran, quality is integrated into every stage of production — from raw material selection to final batch validation. All WICSilicone products are tested in our ISO 17025-accredited laboratory according to certified procedures (ISO, DIN, JIS) for mechanical, thermal, electrical, and chemical performance.
Testing Criteria
| Category | Key Tests |
|---|---|
| Mechanical | Tensile strength · Elongation · Tear resistance · Shore hardness (A/D) · Rheometry (ML/ΔT) · Thermal shock |
| Electrical | Dielectric strength · Insulation resistance · Capacitance · Corona & tracking resistance (HV) |
| Thermal / Chemical | Heat aging · Thermal stability (TGA/DSC) · Oil/solvent immersion · Chemical resistance · Low-temp flexibility |
| Environmental | Salt spray · Weathering (UV/ozone) · Flame resistance (UL94 / FMVSS) · Humidity cycling |
Automotive components are subjected to flame resistance, thermal cycling, high-voltage insulation, megger, erosion, and salt spray testing, while silicone materials and molded or extruded products are evaluated for tensile strength, elongation, rheology, hardness, thermal shock, and insulation properties. In collaboration with the National Standard Institute since 2002, all products are validated for consistent performance and durability under defined automotive and industrial operating conditions.
Each batch is fully traceable and supported by certified documentation, including Certificates of Analysis (CoA), batch records, and compliance reports verifying conformity with FDA, USP Class VI, RoHS, and REACH standards. This ensures consistent reliability across medical, automotive, industrial, and food-grade applications.
