JSIS Engineering - FRAS Polyurethane - Built for Underground Mining
When it comes to FRAS Polyurethane for the underground mining sector, compliance isn't simply about being "flame resistant.", our FRAS polyurethane products are developed and manufactured with the requirements of TRG 3608 – Non-Metallic Materials for Use in Underground Coal Mines at the forefront. Our approach combines controlled manufacturing, rigorous testing, quality assurance, and product traceability to deliver polyurethane products suitable for demanding underground mining environments.
🔥 Fire Resistance Testing
Our polyurethane formulations are assessed against the applicable fire performance requirements, including testing for:
· Ignitability
· Flame propagation
· Flame resistance
· Oxygen index and related fire performance characteristics where applicable
The polyurethane must also be designed and tested to control the build-up of electrostatic charge. Static electricity can create a potential ignition source in an underground coal mining environment, particularly where combustible gases or dust may be present. That's why the electrical properties of the polyurethane formulation and finished product are an important part of the FRAS assessment.
⚡ Anti-Static Testing
· ⚡ Electrical resistance testing
· 🔬 Verification to the required electrical properties
· 📋 Maintaining consistency between the tested formulation and production batches
Materials used underground must also address electrostatic risks, with electrical resistance properties assessed to ensure the material meets the applicable requirements.
Different underground applications can require specific assessment and testing, including products used for: Ventilation, Minor Conveyor, and Non-Defined Applications.
🏭 Manufactured with Quality & Traceability in Mind
At JSIS Engineering, we maintain a robust QA approach designed to ensure that our approved formulations and manufacturing processes remain controlled from raw material through to finished product.
For underground mining, FRAS compliance is not just a label, it is a combination of material performance, testing, manufacturing control, and application specific requirements.
