Core Advantages of EPDM - EPDM features excellent weather resistance, ozone resistance, high and low temperature resistance, water resistance, steam resistance and superior electrical insulation. Its main drawback is poor resistance to oil and fuel. It is the preferred sheath material for outdoor, high-voltage and long-term anti-aging scenarios in new energy and power industries. I. Typical Applic...
For industrial buyers worldwide, selecting the right rubber seal requires clear understanding of temperature resistance, oil resistance, and pressure rating—three core parameters that directly determine reliability and service life. This guide breaks down key performance data and matches them to real working conditions. Temperature Resistance · EPDM: -50℃ to +150℃. Excellent for outdoor, water sys...
Dimensional inconsistency remains the top headache for rubber hose applications in automotive, industrial and HVAC systems. Minor deviations in inner diameter, outer diameter or wall thickness will directly cause assembly failure, sealing leakage, pressure resistance reduction and premature equipment failure. End-to-end standardized production covering rubber mixing, extrusion, vulcanization and c...
For global rubber product buyers, authoritative third-party testing is an essential credential for customs clearance, market access and batch quality verification. In-house factory tests cannot meet EU, North American and Southeast Asian import audit requirements. Standardized third-party testing covers three core modules: material composition testing, physical performance testing and regulatory c...
Primary vulcanization can basically shape rubber products, but it cannot fully remove residual vulcanizing agents, volatile impurities and internal molecular stress. For high-performance special rubber including silicone rubber, FKM fluoroelastomer and HNBR, secondary vulcanization (post-curing) is an indispensable finishing process. It greatly optimizes molecular crosslinking structure, and signi...
