Bulb trim seals are sealing and insulation products with bulb and retainer sections. The bulb portion is often rounded or teardrop-shaped, but may resemble a half-moon or have a flat bottom. The retainer portion of the seal has a U-shape with an open end and two “legs”. The bulb provides sealing and insulation under compressive force, and the retainer or trim section presses onto the flange or substrate.
Each section of the seal (bulb and trim) are made of different materials. In turn, each material has a different durometer or hardness to support compression. For technical buyers and product designers, it’s important to choose the right materials and account for design factors such as bulb size, gap or edge thickness, and minimum bend radius. The following sections explain. (more…)
