Custom Self Adhesive Silicone Sponge Strips

Custom Self Adhesive Silicone Sponge Strips

Product Description

Custom self adhesive silicone sponge strips are high‑performance closed‑cell silicone foam sealing components manufactured through professional foaming, vulcanization, and precision cutting processes, with strong pressure‑sensitive adhesive backing applied in an automated coating line. Made from premium food‑grade or industrial‑grade silicone raw materials, these strips feature uniform cell structure, excellent softness, high resilience, temperature resistance, aging resistance, and tear resistance. As a professional silicone sponge gaskets manufacturer, we provide fully customized solutions for width, thickness, length, color, density, and adhesive strength. Custom self adhesive silicone sponge strips are widely used for reliable sealing, shock absorption, anti‑collision, sound insulation, dustproofing, and waterproofing in industrial equipment, mechanical assemblies, electrical cabinets, home appliances, and furniture, delivering long‑term stable performance in harsh environments with easy peel‑and‑stick installation.

Manufacturing & Production Process

1,Raw Material PreparationHigh‑purity silicone rubber, foaming agent, crosslinking agent, and anti‑aging additives are precisely mixed to ensure stable material performance.

2,High‑temperature Foaming & VulcanizationContinuous siliocne extrusion production line with precise temperature control forms uniform closed‑cell silicone sponge strips with consistent density and elasticity.

3, Primer Coating & Lamination of silicone sponge strips with double side tapes , Load both silicone sponge strips and double side taps on the  self adhesive silicone sponge strip laminating and cutting machine, primer coat the silicone sponge strip surfaces to activate the surface for good adhesion with double side tapes .the laminating machine will then laminate silicone sponge strips with double side tape together with good adhesion and without dislocation

Below youtube video of working process .

4,Precision Cutting to length Automatic cutting laminated silicone sponge strips with double side tapes to length by the self adhesive silicone sponge strip laminating and cutting machine

5. Quality Inspection & PackagingFull inspection of appearance, size, adhesion, resilience, and performance before rolling and packaging.
