Irregular Shape Sealing Silicone Strips

When you need to design custom irregular shape Sealing Silicone Strips, don’t know which factory is better? The answer is, please contact Aobo Silicone to design as we are customized irregular shape sealing silicone strips manufacturer and supplier and factory for many domestic and oversea projects.

Our custom-shaped sealing silicone strips as silicone sealing products with non-standard, customized cross-sectional structures, as opposed to standard-profile silicone strips (such as those with regular cross-sections like round, square, rectangular, etc.). Currently, the most commonly designed profiles by our customers include E-shaped, P-shaped, and D-shaped sealing silicone strips. These strips are mainly used to fill irregular gaps, fit special installation spaces, and achieve functions such as sealing, waterproofing, dustproofing, shock absorption, and sound insulation.

Their primary function is to form a sealing barrier between two contact surfaces. It’s like putting an invisible raincoat on doors and windows—it not only keeps out wind and rain but also provides sound insulation and thermal insulation.

Unique Value

Dynamic Adaptability: It can deform according to the shape changes of the contact surface.

Cushioning Protection：It absorbs vibration and impact.

Environmental Isolation：It effectively blocks dust, noise and heat transfer.

Charm of Customization:  Did you know? The biggest feature of customized sealing silicone strips lies in their "irregularity"! Whether it is for complex mechanical structures or irregular gaps in doors and windows, they can be tailor-made for a perfect fit, ensuring seamless sealing without any dead corners.

Wide-ranging Applications: Irregular shape sealing silicone strips can be found everywhere, spanning from automobile manufacturing and household appliances to building doors and windows and electronic devices. Specific application fields include automobiles, doors and windows, cabinets, refrigerators, containers and other industries. In accordance with the requirements of different sectors, we have successively developed proprietary products such as automotive sealing strips, mechanical sealing strips and door & window sealing strips. Therefore, they are widely used in industries requiring sealing solutions, including electronics and electrical engineering, lighting, pharmaceuticals, chemical engineering, mechanical equipment, textile and chemical fiber, and automotive manufacturing.

They silently guard every gap, preventing the intrusion of dust and moisture—truly the unsung little guardians in daily life and industrial production!

Characteristics of Irregular Shape Sealing Silicone Strips

Irregular shape sealing silicone strips boast excellent sealing performance, high and low temperature resistance, weather resistance, aging resistance and impact resistance, as well as shockproof and waterproof properties. They can fit various smooth surfaces perfectly.

Self-adhesive tape can be attached for enhanced sealing effect. The high-temperature resistant adhesive ensures long-term use without falling off. The product is eco-friendly, safe, good in insulation, high-temperature resistant, low in compression set, strong in resilience and non-toxic.

Smell Test

Products made of high-quality silicone materials generally have a slight acidic odor or almost no noticeable smell. In contrast, low-quality products usually emit a strong, pungent odor that causes discomfort.

Cut Test

Cut the product and observe it carefully after leaving it for a period of time. The cut surface will form a curved shape instead of being completely flat. The higher the curvature, the higher the silicone content and the better the product quality. This phenomenon is particularly obvious for products just finished by high-temperature vulcanization.

Burn Test

When a high-quality foam silicone strip is burned, the smoke produced during and after combustion is accompanied by white or gray ash. There is no obvious pungent odor. The product features high strength, long service life, insulation, eco-friendliness, resistance to high and low temperatures, compression resistance, acid and alkali resistance, aging resistance, UV resistance, smooth surface, uniform foam density, excellent surface non-stickiness and good air permeability. Made of 100% premium silicone raw materials and subject to rigorous testing, it complies with environmental protection standards.
