Transparent Gaskets & Seals
Clear gaskets and O-rings where the seal must stay visually clean — sight-glass seals, display seals and sanitary applications.
Optical & Transparent Silicone Molding
Optically clear and transparent silicone with high light transmission and low haze — for transparent gaskets, light-guide seals, optical overlays and clear components. Compounded in-house from global feedstocks and molded to your optical, dimensional and sealing requirements.
Optical & Transparent Silicone
Clarity and Flexibility in One Material
Silicone is unique among clear materials: it stays transparent while remaining flexible, heat-tolerant and sealable — a combination rigid optics materials like PMMA or PC cannot match. We compound transparent and optically clear grades in-house, so the transmission, haze and tint are tuned to your part rather than taken from a fixed catalog grade.
- High light transmission, low haze — clear grades for optical and sealing functions
- Platinum-cured, UV & heat stable — resists yellowing over the part's life
- Flexible sealing — clarity plus a compliant, IP-rated seal in one part
- Food & medical grades — FDA / LFGB and platinum-cured options
Clear Silicone Applications
Where Transparent Silicone Fits
Light-Guide Seals
Flexible silicone that both seals and transmits light around LEDs, indicators and edge-lit displays without separate light pipes.
Optical Overlays
Clear protective overlays and membranes for buttons, sensors and displays that must transmit light while sealing out dust and moisture.
Clear Components
Transparent tubing, covers and molded parts where the user or machine needs to see through the component.
Food & Beverage Contact
FDA / LFGB clear silicone for drinkware seals, sight tubes and dispensing components that stay crystal clear in use.
Medical & Lab
Platinum-cured clear silicone for tubing, seals and components where visibility and biocompatibility matter.
Material & Process
Compounded and Molded In-House
Transparent and optically clear grades are compounded in-house from global silicone feedstocks, so we control the clarity, tint and cleanliness of every lot. Molding runs on our in-house silicone and LSR equipment with controlled processing to hold the optical surface quality.
- In-house compounding — feedstocks from suppliers including Elkem, Dow and DuPont
- Compression, LSR & overmolding — the right process per geometry
- Incoming-lot testing — every raw-material lot verified before production
- Measured, not labelled — we report the actual transmission and haze, not a generic grade name
Whether you need a fully transparent part or a lightly tinted brand color, the tint and clarity are dialed in during DFM review against your optical target.

Why CYES
Clarity You Can Verify
DFM for Optical Targets
Wall thickness, gate placement and polish are reviewed up front so the molded part meets your transmission, haze and sealing targets on the first shot.
Surface Quality Control
Parting lines, flow marks and surface finish are inspected so clear parts stay optically clean, not just dimensionally correct.
One Supplier, Full Traceability
Compounding, molding and inspection all happen in-house, so every clear lot is traceable from feedstock to shipment.
