Silicone rubber for OEM parts and fabrication
Silicone rubber is a flexible elastomer used where buyers need heat tolerance, flexibility, and stable performance across temperature. B2B buyers source it in three main formats: flat sheet and rolls, extruded profiles and tubing, and compression- or injection-molded parts. This page is a materials overview; each format has its own spec page.
Ratings (temperature, tensile, elongation) are confirmed by SKU on the spec sheet on request — we do not publish blanket numbers.
Hardness
Shore A hardness: choosing a band
Silicone rubber hardness is specified in Shore A. Softer bands suit seals, grips, and skin-contact parts; mid bands suit general gaskets and molded goods; firmer bands suit parts that must hold shape. Tell us the use and we confirm the band on the sample. See the silicone spec guide.
Grades
Grades buyers ask about
- General-purpose — industrial parts and seals.
- Food-contact — kitchen and food-processing parts; files in the documentation pack on request; background in the food grade silicone guide.
- Translucent or colored — Pantone matching quoted per SKU.
Grade and COA are tied to the quoted compound.
Formats
Sheet, extrusion, and molding
- Sheet and rolls — die-cut pads and gaskets: silicone sheet.
- Extrusion — tubing, hose, cords, and profiles: silicone tubing.
- Seals and gaskets — silicone gaskets.
- Molded parts — custom parts from your drawing: custom molded silicone and silicone mold making.
- Tape — silicone tape.

Silicone Rubber FAQ
Do you sell raw silicone rubber compound?
No — we supply finished sheet, extruded, and molded silicone rubber products for B2B buyers, not raw compound or chemicals.
What Shore A hardness can you supply?
The hardness band is quoted by SKU / spec sheet and confirmed on the sample.
Is your silicone rubber food grade?
Food-contact compound is quoted by spec; files and COA on request.
Can you make a custom silicone rubber part?
Yes — custom molded parts go through drawing review, tooling, and sample before bulk.
What MOQ applies?
MOQ is quoted by SKU and format.
