Item No. SP-019
Our high-performance silicone profiles are purpose-built to deliver reliable sealing, thermal insulation, and long-term structural integrity in the most challenging operating conditions. Manufactured exclusively from 100% virgin silicone material, every profile offers consistent quality, superior flexibility, and outstanding resilience against environmental stressors including extreme heat, sub-zero temperatures, continuous UV exposure, ozone, and aggressive chemicals.
Unlike blended rubber or lower-grade elastomers, our silicone extrusions maintain their physical properties over a wide service temperature range and resist hardening, cracking, or swelling – ensuring a maintenance-free service life in critical applications.
Thermal Stability: Serviceable from -60°C to +230°C (-76°F to 446°F) with intermittent peaks up to 260°C (500°F).
Weather & UV Resistance: Exceptional resistance to sunlight, rain, snow, and ozone – ideal for outdoor and marine environments.
Chemical Inertness: Resists acids, alkalis, oils, solvents, and cleaning agents.
Low Compression Set: Retains original shape and sealing force even after prolonged compression.
Dielectric Strength: Excellent electrical insulator for electronic and HVAC applications.
Non-Toxic & Odorless: Food-grade options comply with FDA, LFGB, and EU regulations.
Flame Retardancy: Self-extinguishing grades available (UL94 V-0).
100% Virgin Silicone – No regrind or fillers. Full traceability and consistent batch-to-batch performance.
Tight Tolerances – Precision extrusion down to ±0.05mm for a perfect sealing fit.
Fast Customization – Prototype samples available in 5–7 working days with in-house tooling.
Full Compliance – FDA, REACH, RoHS, and UL94 V-0 certified options available.
End-to-End Support – From material selection to installation guidance, we engineer complete solutions.
HVAC & Refrigeration – Air duct seals, cabinet gaskets – reduces energy leakage.
Automotive & EV – Battery pack seals, door weatherstripping – resists heat, oil, and vibration.
Building & Glazing – Window perimeter seals, curtain wall gaskets – waterproof and UV-stable.
Food Processing – Tank gaskets, conveyor scrapers – FDA-compliant platinum-cured silicone.
Electrical & Solar – Junction box seals, panel gaskets – excellent dielectric insulation.
Marine – Hatch and porthole seals – withstands saltwater and humidity.

Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
Standard Rolls: Goods are typically supplied in 50m or 100m continuous rolls, precision-coiled to maintain the profile’s structural shape.
Max operating temperature?
Continuous use from -60°C to +230°C (-76°F to 446°F), with peaks up to 260°C.
Solid vs. sponge silicone?
Solid = high pressure/abrasion resistance. Sponge = high compressibility for uneven gaps.
Self-adhesive available?
Yes, acrylic or silicone-based PSA on one or both sides.
FDA-approved for food contact?
Yes, meets FDA 21 CFR 177.2600 and EU 1935/2004.
MOQ for custom profiles?
No fixed MOQ. Trial orders from 200 meters; samples available from 1 meter.
Lead time for custom dies?
Prototype: 5–7 working days. Production tooling: 10–15 days.
Installation tips?
Clean surface with isopropyl alcohol, apply firm pressure, avoid stretching. Full bond strength in 24 hours.
