II. Flagship Products: An In-Depth Look at the Silicone Rubber Compound Portfolio
Sanexin Polymer’s silicone rubber product lines are strategically segmented to address diverse application scenarios with precision. Whether your priority lies in maximizing mechanical strength or meeting stringent flame-retardant environmental standards, the optimal solution resides within our portfolio.
1. General-Purpose and High-Tear-Strength Series (SR 3100U – SR 3370U)
- Core Advantage: Excellent processability, smooth mold release, and well-balanced physical properties.
- Targeted Application: Complex molded articles and large-dimension extruded profiles (e.g., specialty cable sheathing, conveyor belts).
- Performance Metrics: Take SR3350U as a benchmark: tensile strength reaches 10.2 MPa, elongation at break is an impressive 810%, and tear strength achieves a remarkable 45 KN/m. This robust combination ensures that Sanexin silicone parts resist cracking under high tensile stress or sharp-edge compression, delivering a service life significantly longer than conventional compounds. As a high tear strength silicone rubber for complex extrusion profiles, this series excels in demanding fabrication processes.
2. Low Compression Set and Oil-Resistant Series (SR2100UOR – SR2270U)
- Core Advantage: Minimal compression set, high resilience, and robust oil resistance.
- Targeted Application: Sealing components subjected to prolonged compressive stress, such as O-rings and gaskets in engine peripheries.
- Performance Metrics: Under rigorous testing at 177°C for 22 hours, compression set values are as low as 11%-15%. This demonstrates the material’s ability to maintain tight elastic recovery and prevent leakage even after extended high-temperature service. For applications requiring a low compression set silicone rubber for automotive seals, this series provides an ideal balance of durability and sealing integrity.
3. High-Temperature-Resistant Hot Stamping Roller Series (SR1200UTH)
- Extreme Performance: A specialty product line developed by Sanexin for extreme high-temperature operations.
- Application Scenario: Suitable for hot stamping rollers operating in 300°C environments or similar extreme thermal conditions.
- Technical Highlight: While standard silicone rubber tends to harden and degrade rapidly above 250°C, Sanexin’s SR1280UTH utilizes a proprietary formulation to retain elastomeric flexibility at these elevated temperatures. This makes it an ideal candidate for high temperature resistant silicone rubber for hot stamping rollers in the premium printing and thermal transfer industries.
4. Low-Smoke, Halogen-Free, Environmentally Friendly Flame-Retardant V0 Series (SR6200UFR – SR6800UFR)
- Safety First: As safety standards evolve within the new energy and appliance sectors, UL94 V0 flame retardancy has become a non-negotiable global requirement.
- Sanexin Solution: A comprehensive range spanning from economical grades (SR6600UFR) to high-strength variants (SR6800UFR).
- Key Specifications:
- Flammability Rating: UL94 V0 certified.
- Electrical Insulation: Comparative Tracking Index (CTI) achieves Class 1A4.5, making it particularly suitable for high-voltage insulators and electrical sealing applications.
- Environmental Profile: Low smoke and halogen-free formulation, producing minimal corrosive smoke during combustion and thus protecting sensitive electronic components from secondary damage. We are a qualified UL94 V0 flame retardant silicone rubber compound supplier committed to safety and performance.
5. Anti-Static and Conductive Silicone Rubber Series (SR810000UEC – SR836009UEC)
- Precision Resistivity Control: Sanexin precisely tailors surface resistivity across a range from 10^3 Ω to 10^9 Ω.
- Differentiated Customization:
- SR815003UEC: Formulated for precision electronic trays requiring rapid electrostatic dissipation.
- SR825006UEC: A low-staining, non-marking formulation to prevent contamination of contact surfaces.
- SR836009UEC: Colorable ESD silicone rubber. This innovation overcomes the traditional limitation of anti-static materials being available only in black, enabling enhanced product aesthetics without compromising ESD protection. This is made possible by our advanced colorable ESD silicone rubber custom compounding service.

IV. Frequently Asked Questions (FAQs) About Silicone Rubber Customization and International Procurement
Q1: As an overseas customer procuring silicone rubber compound from China, how can I be assured of batch-to-batch consistency?
A1: Batch consistency is the cornerstone of our export operations. Sanexin Polymer employs a proprietary formulation database and rigorously controlled process parameter lock-down procedures. Every batch of compound is manufactured according to identical formulations, processes, and equipment settings. Prior to shipment, each batch undergoes sampling and testing of critical physical properties, accompanied by a detailed Certificate of Analysis (COA). For long-term international partners, we retain retention samples of each batch for a minimum of 12 months to facilitate traceability and verification. We provide a silicone rubber compound with detailed COA and technical data to ensure complete transparency.
Q2: Our application requires a unique combination of low compression set and high oil resistance. Standard grades are insufficient; can Sanexin develop a custom formulation for us?
A2: Custom formulation development is precisely our core competency. You need only provide the specific service conditions—temperature profile, contacting media, pressure parameters, and target service life. Our technical team will then leverage our existing low compression set, oil-resistant SR2100UOR series as a foundation for targeted modification or, if necessary, design an entirely new compound specific to your requirements. We support the full development cycle, from laboratory-scale trials and pilot production to full-scale manufacturing. We also provide complimentary samples for your preliminary evaluation and testing.
Q3: We are interested in evaluating Sanexin’s products, but international shipping costs and transit times for samples can be prohibitive. Are there more efficient options?
A3: We fully appreciate the cost considerations involved in international sampling. Sanexin Polymer typically recommends consolidating your trial material requests; we can dispatch multiple similar grades in a single shipment for parallel evaluation, effectively amortizing the freight expense per sample. Additionally, we are flexible in arranging shipping via your designated FedEx/DHL collect account or advising on the most cost-effective international courier options based on sample weight. For prospective customers demonstrating serious long-term partnership intent, we are often able to offer favorable accommodations on initial sample costs and freight charges.
