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.
