Frequently Asked Questions
Q
What is the operating temperature range of your silicone products?
Our silicone strips and tubes are designed for long-term stable performance from -60°C to 250°C, with short-term exposure tolerance up to 300°C. They maintain flexibility at cryogenic temperatures, making them suitable for extreme environments such as automotive engine compartments and polar expedition equipment.
Q
Are your silicone products compliant with food contact and medical safety standards?
Yes. Our products are certified to FDA 21 CFR 177.2600 for food contact applications and meet ISO 10993-5 cytotoxicity standards for medical use. They are also RoHS 2.0, REACH SVHC, and EU EN71-3 (toy safety) compliant, with no detectable phthalates, PAHs, or heavy metals.
Q
Can you produce custom silicone profiles with specific shapes and dimensions?
Absolutely. We support fully custom cross-sectional designs including rectangular, trapezoidal, and hollow profiles with a dimensional tolerance of ±0.1mm. We also offer surface treatments such as 3M adhesive backing, foam processing, textured surfaces, and Pantone color matching with laser-engraved logos for traceability.
Q
What is the waterproof and sealing performance of your silicone products?
Our silicone sealing products achieve an IP68 waterproof rating (1m depth for 30 minutes) with a helium leak rate of ≤0.01 cm³/min. The volume resistivity is ≥1×10¹⁴ Ω·cm with a dielectric strength of ≥20 kV/mm, and UL94 V0 flame retardancy is standard, making them ideal for submersible devices and high-reliability electrical applications.
Q
How long does it take to receive samples, and what quality documentation is provided?
We offer free samples for first-time clients with a turnaround time of 5–7 business days from receipt of 3D drawings to prototype delivery. Every order is supported by SGS full-test reports covering physical properties, chemical safety, and aging tests. A 12-month warranty is included with all products.
Q
Are your silicone products environmentally friendly and sustainable?
Yes. Our silicone materials are 100% recyclable in compliance with the EU ELV directive. Our production process is solvent-free with VOC emissions below 50 mg/m³, and we hold ISO 14001 environmental management certification, reflecting our commitment to low-carbon, sustainable manufacturing.
