NBR Foaming Stopper for Anti-Dust Sealing Applications

Product Introduction 1. Core Product Overview Classified under Anti-dust Sealing product category, NBR foaming stopper is foamed from nitrile butadiene rubber raw material into porous elastic structure with customizable irregular outline, specially designed for gap plugging and protection of refrigeration equipment, automated machinery and domestic electrical appliances. Optimized foaming formula balances lightweight porous texture and stable compression recovery performance, enabling the stopper to keep tight embedded state inside uneven assembly gaps after long term extrusion caused by equipment thermal expansion and continuous mechanical vibration. The flexible rubber body can adapt to slight dimensional change of mounting gaps without additional trimming during field installation work. All finished foaming stoppers pass alternating high low temperature aging and repeated compression fatigue testing before factory delivery to maintain stable comprehensive performance amid varia…
