Antimicrobial RTV Molds: Silver-Ion Additive Limits
Silver-ion additives can reduce bacteria on a plaque screen. They don't sterilize a mold or the casting. Don't stir flake into RTV; cleaning still owns
Read article -Silicone Mold & Manufacturing Guides
Explore practical silicone mold guides from RUUIPON, covering design, release, materials and production planning. Start with the problem you need to solve, then open the relevant product page when you are ready to discuss a quotation. CAD, drawings, samples and measured reference photos can all help define the project.
Start With These Core Guides

Barium-Filled RTV: Radiopaque Castings vs Mold Rubber
Barium sulfate makes silicone radiopaque or, at high loading, an attenuator. Don't dump BaSO4 into a mold cup. Put the filler in the article, not the

Cryogenic RTV Molds: Tg vs Crystallization at -100 C
Some silicones stay rubbery near -100 C if crystallization is suppressed. Most RTV molds are not cryogenic tools. Test the cavity or part cold after a

Implant Silicone: ISO 10993 Map, Not an RTV Mold Stamp
Long-term implantable silicone needs ISO 10993-1 on the finished device. An RTV mold is tooling. This page is a map, not a filing or implant-approved

RTV Silicone Outgassing: E595 Screen vs E1559 Rates
ASTM E595 is a 24 h TML/CVCM screen. Optics often need rates (ASTM E1559) and a bake. Tin RTV keeps outgassing; platinum can be a candidate after vacuum

Silica vs Quartz Fillers in RTV Molds: Shrink and Flow
Fumed silica builds RTV viscosity and tear. Quartz flour loads higher, abrades, and is the wrong shrink knob on platinum jackets. Do not invent a shop

Magnetic RTV Silicone: Ferrite Loading vs Mixability
Magnetic RTV is ferrite in polysiloxane. More powder means more pull and a paste that won't mix. Spec the function, not a loading. Keep ferrite off food

Glow-in-the-Dark RTV Molds: SrAl vs ZnS Mix Control
Glow silicone is SrAl or ZnS pigment in polysiloxane. Keep coarse phosphor out of a precision mold face. Mixing control beats a shop-invented loading

RTV Heat-Sink Potting: Alumina, BN, and the Bond Line
Thermally conductive silicone is alumina- or BN-filled paste. Heat follows a thin path onto metal. The potting mold locates the sink; don't invent watt
