How to Judge the Quality of Industrial Rubber Products? 6 Core Testing Standards
In industrial procurement, many buyers cannot accurately judge the quality of rubber products, resulting in problems such as short service life, poor sealing, easy aging, and frequent replacement of purchased parts. Qualified industrial rubber products must pass professional physical performance testing and environmental certification.
We summarize 6 core testing standards for high-quality industrial rubber products, helping customers quickly identify high-standard rubber parts and avoid low-quality defective products:
Testing Standard | Qualified Standard Value | Quality Judgment Description |
|---|---|---|
High Temperature Aging Test | No crack, no deformation after 168h @100℃ | Ensure long-term high-temperature working stability |
Low Temperature Resistance Test | No brittle cracking at -40℃ | Adapt to low-temperature regional environment |
Oil Immersion Test | Volume change rate ≤5% | No swelling failure in oil medium |
Compression Permanent Deformation | ≤10% | No collapse after long-term compression sealing |
Tensile Elongation | ≥200% | Tough and not easy to break |
Environmental Protection Test | Meet ROHS & REACH | No harmful substances, meet export standards |
All our rubber products are tested one by one according to the above standards before delivery. We provide test reports and certification documents to support customer project inspection and customs clearance, ensuring that every batch of products is stable and qualified.
