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...
Food and beverage production demands ultra-safe, contamination-free production accessories. Food-grade rubber hoses and sealing components are core consumables for material transmission and equipment sealing, directly affecting product hygiene and global market compliance. All our rubber solutions strictly follow FDA, EU 1935/2004 and REACH standards, with mature industrial application cases for f...
The chemical industry features harsh production environments with strong acid, strong alkali, organic solvent, and high-temperature mediums. Ordinary rubber parts are prone to swelling, cracking, aging and leakage, causing equipment failure and safety hazards. As professional chemical-grade accessories, fluororubber (FKM) hoses and sealing parts deliver extreme corrosion resistance, high-temperatu...
Shore hardness serves as a core parameter for the selection of industrial rubber products, directly determining the fitting tightness, compression resistance and service life of rubber seals, hoses and gaskets. Most equipment issues such as medium leakage, poor fitting and premature aging stem from improper rubber hardness selection. For global purchasers and engineering technicians, mastering the...
High-precision rubber gaskets and molded sealing parts are critical components for industrial equipment sealing, where dimensional tolerance directly determines sealing tightness, pressure resistance and long-term operational stability. Ordinary molding processes are prone to dimensional deviation, shrinkage deformation and edge burrs, leading to assembly gaps, medium leakage and equipment failure...
Choosing the right rubber material is critical when designing components for automotive applications. Different parts are exposed to different operating conditions, from engine heat and oil to moisture, ozone, and outdoor weathering. EPDM, NBR, and silicone rubber each offer different characteristics for these environments, making material selection an important part of component design. EPDM is w...
