Every production lot at Kaxite is tested before shipment. Our in-house lab checks density, tensile strength, friction behavior, and chemical resistance — and issues a material test report (MTR) with EN 10204 3.1 certification for each batch. For B2B buyers, this means the packing you receive is backed by data, not just a declaration.
| Test | Purpose | Reported in MTR |
|---|---|---|
| Density | Confirms material consistency and compression behavior | Yes |
| Tensile strength | Verifies fiber and braid integrity | Yes |
| Friction coefficient | Indicates shaft wear and running performance | Yes |
| Chemical resistance | Checks compatibility with specified media and pH range | Yes |
| Impregnation content | Confirms graphite or PTFE loading | Yes |
Each batch is assigned a lot number at the raw fiber stage. That lot number follows the material through twisting, braiding, impregnation, testing, and packaging. If a customer needs to trace a finished packing back to its raw material, we can provide the full production and test record.
Tell us the product and specification. We will send a sample MTR and technical data sheet for your evaluation.
