Custom Silicone Strips and Flat Gaskets for Sealing and Isolation

Skytech Ultrafab Silicone Rubber Strips and Gaskets are flat extruded and cut silicone profiles for door seals, panel gaskets, equipment enclosure seals, cleanroom construction joints, and vibration isolation pads across pharmaceutical, food, cleanroom, and industrial applications. Manufactured from FDA-compliant platinum-cured silicone in sheet, strip, and custom-cut flat gasket forms, they provide flexible, temperature-resistant, and chemically inert sealing across the widest application range of any elastomer.

What Are Silicone Rubber Strips and Gaskets?

Silicone Rubber Strips are continuous-length flat extrusions of silicone rubber — typically rectangular in cross-section — used as door seals, edge protectors, and panel joint seals. Silicone Flat Gaskets are cut from silicone sheet to a specific shape that matches a flange, hatch, or equipment face — providing a conformable, compressible seal between two flat surfaces. Both are fabricated from the same platinum-cured silicone compound as Skytech O-rings and cords, ensuring consistent pharmaceutical and food compliance.

Features and Benefits

• Sheet and Strip Supply Forms: Available as continuous strip extrusions for door and panel seals, or as sheet goods for die-cutting or water-jet cutting custom gasket shapes to any flange or hatch geometry
• FDA-Grade Platinum-Cured Silicone: 21 CFR-compliant material for direct food and pharmaceutical product contact — no restricted plasticisers, fillers, or processing aids in the compound
• Multiple Thickness Options: 1 mm to 25 mm thickness available in strip and sheet form — thicker sections provide greater sealing under low clamping loads; thinner sections for precision gaskets with accurate compression control
• Custom Width and Length: Strips extruded in any width from 5 mm to 300 mm and supplied in continuous rolls or cut lengths — gaskets cut to any shape from sheet goods up to 1200 mm × 1200 mm
• Temperature and Steam Rated: Continuous service to 200°C; withstands repeated 134°C autoclave steam cycles — remains flexible and elastic at cryogenic temperatures down to -60°C
• Vibration Isolation Pads: Thick silicone sheet sections used as anti-vibration pads under pharmaceutical and food processing equipment — isolates equipment vibration from the floor structure and reduces noise transmission

Technical Specifications

Applications

• Cleanroom Panel Construction: Perimeter and panel joint seals in cleanroom wall, ceiling, and floor system construction — silicone strips seal joints to ISO particle class without adhesives that could outgas or shed particles
• Pharmaceutical Equipment Doors: Door seals on pharmaceutical dryers, granulators, coating pans, and process vessels — FDA silicone withstands steam cleaning and chemical sanitising without degradation
• Food Processing Machine Sealing: Oven door seals, chiller door gaskets, and mixing vessel cover seals in food processing equipment — food-grade silicone resists steam, food acids, and cleaning detergents
• HVAC Duct Joints: Flexible duct joint seals in pharmaceutical and food industry HVAC systems — silicone maintains seal integrity across the operating temperature range of supply and return air ducts
• Vibration Isolation: Anti-vibration pads under tablet presses, centrifuges, and process equipment — thick silicone sheet sections isolate mechanical vibration and reduce noise transmission to adjacent areas

Why Choose Skytech Ultrafab for Silicone Rubber Strips & Gaskets?

• Sheet or Strip — Any Shape: Custom gaskets cut from sheet goods in any shape and tolerance — no minimum order on custom shapes, and prototype gaskets produced from drawings within 5–7 working days
• FDA Material Documentation: 21 CFR certificates, compression set data, and platinum-cure confirmation supplied for pharmaceutical facility qualification — standard documentation package ready to issue
• Complete Silicone Programme: Order silicone strips and gaskets together with Skytech O-rings, cords, inflatable gaskets, and autoclave gaskets — complete pharmaceutical and food silicone sealing programme from one source
• Wide Hardness and Thickness Range: Correct hardness and thickness specified for each application — door seals, panel gaskets, and vibration pads all require different compression characteristics that the Skytech range covers
• Competitive Direct Pricing: Direct manufacturer pricing on silicone sheet and strip — significant cost advantage over distributors for both sample quantities and bulk supply orders for facility-wide programmes
