NBR stopper for Anti dust Sealing

Product Introduction   1. Core Product Overview   Classified under Anti-dust Sealing product category, NBR stopper is compression molded from high density nitrile butadiene rubber with exclusive irregular hollow cutout structure, designed to wrap and fit around protruding component terminals of various industrial power and automated machinery. The special hollow contour is precision die cut according to equipment terminal dimension, allowing tight wrapping installation without extra trimming during on site assembly. Selected NBR raw material balances durable compression resistance and moderate elastic shrinkage, so the finished piece can keep tight attaching state after long term repeated extrusion from equipment vibration and temperature shift. All finished stoppers pass fatigue compression and ambient aging inspection before factory delivery to guarantee stable comprehensive performance in complex industrial operating surroundings. 2.
