Description
Custom Flame Retardant Silicone Coated Rollers Fire Safety | Non-Marking Wheels for Smooth Conveyor & Fire Safety
Why Choose This Product
Flame retardant silicone coating is the key differentiator in fire-sensitive industries such as tunnel ventilation, food processing, and chemical packaging lines. Our coating compound uses halogen-free flame retardant additives and passed the UL94 V-0 vertical burn test, meaning it stops burning within 10 seconds after the ignition source is removed. This gives plant managers a measurable safety upgrade over standard rubber rollers.
The non-marking surface leaves no black marks on floors or product packaging, which is especially valued in clean conveyor applications where product appearance matters. Combined with the smooth surface finish, these rollers maintain consistent friction and reduce vibration-driven noise during operation.
We support full customization of roller diameter, length, shaft configuration, and hardness. Every conveyor line has different spacing, load, and speed parameters, so our engineering team provides specific recommendations on coating thickness and hardness to match your application. Every batch is tested for hardness, tensile strength, and flame retardant performance; test reports are available with each shipment.

About Us
Customers Visiting
As a China-based manufacturer and OEM/ODM supplier of industrial silicone rollers and elastomer components since 2012, we serve clients in over 50 countries. We offer customization — from roller hardness (Shore A 30°~70°) to core materials and surface patterns. Our products are tested to meet ISO9001 standards, supporting reliable performance for your conveying and fire-safety equipment. Wholesale orders are welcome with competitive direct pricing. We provide expert advice and support from prototype to mass production.
We regularly host customers from Europe, North America, the Middle East, and Southeast Asia at our production base in China. A live tour of our roller production line helps buyers understand the coating process, molding precision, and inspection workflow. Many long-term partnerships started with a factory visit, so if you are planning a trip to China, contact us in advance and we will be happy to arrange a visit with our technical team.
Factory & Equipment
Our workshop is equipped with automated vulcanization presses, CNC grinding and turning machines, dynamic balancing instruments, and a dedicated flame retardant coating production station. This setup enables us to handle both small sample orders and full container shipments with consistent quality. We also maintain a small inventory of semi-finished cores so that custom coating orders can be processed faster.
Our Certifications (ISO9001, RoHS, Testing Reports)
Our quality management system is ISO9001 certified. The flame retardant silicone compound is tested according to UL94 standards, and material test reports are provided with each shipment. We also support third-party inspection before delivery, giving you additional peace of mind on product quality and compliance.
Production & Inventory Policy
Lead time: Actual delivery time can be affected by raw material supply, equipment scheduling, and seasonal peak production. We provide our best estimated delivery date after order confirmation and keep you informed at every stage.
Stock status: We generally do not keep large quantities of finished rollers in stock, but some popular standard sizes are available for quick dispatch. Real-time stock changes with sales and production cycles, so please contact our sales team to confirm availability before placing an order.
Bulk & urgent orders: For bulk or urgent requirements, please communicate your timeline early so our production planning team can make the necessary arrangements. We will do our best to align our schedule with yours.
Frequently Asked Questions
1. Can you produce custom flame retardant silicone coated rollers with non-marking surfaces for our specific conveyor system?
Yes. Our Custom Flame Retardant Silicone Coated Rollers Fire Safety series supports full customization of roller diameter, length, shaft type, shore hardness, and coating thickness. We have supplied non-marking flame retardant rollers for conveyor systems in electronics, food packaging, and logistics industries. Send us your drawings or sample, and our engineering team will provide a tailored solution with a competitive price suggestion.
2. What is the MOQ for custom silicone rollers?
Our standard MOQ is 10 pieces for custom sizes, but for small trial orders we can produce as few as 2–3 samples in our test workshop. Wholesale orders receive more favorable pricing, and repeat orders benefit from our faster production scheduling.
3. How does the flame retardant coating perform in high-temperature or fire-risk environments?
Our silicone coating is formulated with flame retardant additives and meets UL94 V-0 in the vertical burn test. The working temperature range is -40°C to +200°C, which is significantly wider than standard rubber. Every batch is tested against the rated flame retardant class before shipment, and test reports are available upon request.
4. What quality control procedures and certifications do you have?
Our factory is ISO9001 certified, and we follow a batch-to-batch inspection protocol covering hardness, tensile strength, abrasion resistance, and flame retardant performance. We provide material test reports with each shipment and can arrange third-party inspection before delivery.
5. What is the typical delivery time for bulk orders?
Delivery is usually 15–30 working days after drawing confirmation, depending on quantity and custom requirements. Actual lead time can be influenced by raw material supply and seasonal peak production, so we always provide a clear schedule after order confirmation and keep you updated throughout production.
6. Can you provide samples for testing before mass production?
Yes. We can send samples for your evaluation after confirming the specification and price. The sample cost can be credited back in the mass production order. For overseas customers, we arrange express delivery and provide the tracking number promptly.
7. What payment methods and shipping options are available?
We accept T/T, L/C at sight, PayPal for samples, and other methods based on mutual agreement. For shipping, we work with well-known freight forwarders and support FOB, CIF, DAP, and other Incoterms to match your logistics preference.
8. How does a flame retardant silicone roller compare with standard rubber rollers in service life?
In normal continuous conveyor operation, the flame retardant silicone coating typically outperforms standard rubber by 2–3 times in wear resistance. The non-marking property keeps the surface clean and maintains stable friction throughout the service life. This is supported by laboratory abrasion data and customer feedback from high-speed production lines.
