Silicones for Mold Release
CHT offers a broad range silicone and hydrocarbon wax additives as well as world class technical support dedicated to improving your release efficiency with reduced production downtime.
Silicones provide an unrivaled slip and release in a variety of molding applications due to their low surface tension, low affinity for most molded materials and high temperature stability. Add to that silicone’s highly customizable crosslinking chemistries, and our silicone experts can tune CHT’s release fluids and emulsions to be purposely sacrificial, or remarkably durable.
CHT manufactures concentrates and ready-to-use silicone and wax products for the release of thermoplastics, flexible foams, rubbers, composites, polyurethane foams, food grade containers, wood (oriented strand board), tires and diecast to name a few. These different applications make use of the following CHT chemistries that are produced around the globe:
- Hydrocarbon wax emulsions (Keim Additec line)
- Low molecular weight polydimethylsiloxanes (PDMS) - 50-1000 cSt
- Moderate molecular weight PDMS – 1000-60,000 cSt
- High molecular weight PDMS – 100,000-500,000 cSt
- Ultrahigh molecular weight PDMS – 1,000,000 – 120,000,000 cSt
- Highly crosslinking elastomeric PDMS
- Cationically charged PDMS
- Amine-modified PDMS
- Silsesquioxane resin + PMDS
- Emulsions of the above
SILICONE EMULSIONS IN FOOD GRADE APPLICATIONS
Silicones that have been emulsified with FDA-approved ingredients have widespread use in food grade (FG) applications. CHT’s world class emulsification technology affords ultrastable products using these additives, and our technical staff can assist in selecting the most effective product for your specific food grade application. Our current FG product line has been developed to solve our customers’ food and food processing issues with thermoformed package denesting, slip aids, paper hydrophobing, antifoaming and food release. Bring your food-related manufacturing and packaging concerns to CHT’s silicone experts and let us customize an efficient FG emulsion for your application.
Technical Data Sheets for CHT food grade emulsions are available below.
