Material & Sourcing

Silicone Material & Sourcing Center

We work with high-performance silicone compounds. The performance of any final part begins with the purity and stability of the raw compound. Our method is simple:

 
  • Source clean, high-grade silicone materials.
  • Verify every batch before it reaches production.
  • Use only material that meets our standards and your certifications.

Silicone raw material and compound preparation

Material Sourcing & Traceability

We protect material integrity from the start. Every silicone compound – whether from a global brand or a qualified domestic partner – is selected for performance, cost fit, and required certifications.

 

Strategic Material Selection

We choose materials based on the demands of the final product.

  • Global Brands (Elkem, Dow, DuPont):
    Used when a project needs proven consistency, long-term supply stability, or proprietary formulations available only from major international manufacturers.
  • Qualified Domestic Partners:
    Used when faster lead times, flexible custom formulations, or improved cost efficiency matter, while still meeting required quality and certification standards.
  • Data-Driven Choice:
    The Technical Data Sheet (TDS) and the final product’s certification needs guide all material selection decisions.

All partners must hold relevant ISO certifications and provide full batch traceability.

Inventory Management Protocol

We maintain material integrity through controlled storage and usage.

  • TDS Shelf-Life Control:
    Each lot is stocked and used according to its documented shelf life. Most standard compounds remain stable for up to six months.
  • Specialty Materials:
    Short-life or highly reactive compounds move through an accelerated cycle to prevent degradation and ensure steady performance.

Material Application & Compliance

Selecting the right silicone grade ensures long service life and regulatory compliance. We group materials by technical demand, from extreme-temperature environments to high-voltage systems and high-purity applications.

 

Case Study: NEV High-Voltage Cables

Silicone used in new-energy vehicle (NEV) cables must endure constant and harsh loads. For these projects, we specify compounds that:

  • Hold thermal stability from –40°C to 180–200°C for more than 3,000 hours.
  • Resist 600–1000 V while carrying heavy current surges.
  • Maintain tear strength above 30 N/mm with low compression set.
  • Process cleanly during high-speed, bubble-free extrusion.

Quality Assurance & Material Verification

Material integrity is confirmed through documentation and testing. Our quality framework supports high-purity, high-compliance applications across regulated industries.

 

Post-Curing Protocol for Purity

For medical, food-contact, and other high-purity applications, we apply a post-curing (baking) process that:

  • Removes volatiles: Drives off remaining siloxane oligomers and VOCs that persist after initial curing.
  • Supports compliance: Helps meet global standards requiring reduced extractables and strict migration limits.

Mandatory Batch Documentation

Each lot includes a full documentation package:

  • MSDS: Safety, handling, storage, and emergency information.
  • Batch Inspection Report: Dimensional and visual checks on finished components.
  • Optional Certifications: FDA, LFGB, SVHC, RoHS, USP Class VI, ISO 10993, EP (available on request).

External Testing & Validation

Suppliers provide standard third-party certifications with each shipment. For special compliance needs, we extend testing:

  • Use accredited external labs for regional chemical restrictions and detailed analytical testing.
  • Tests may require longer lead times and added cost, always quoted before work begins.
