CHT Silicone Materials - LSR, Foams, Gels, Food-Grade & Specialty Rubbers

CHT Silicone Materials - Global Manufacturer of Professional Silicone Materials

CHT is a global manufacturer of high-quality silicone materials for professional applications: LSR (Liquid Silicone Rubber), molding rubbers, foams, gels, replication materials, food-grade silicones, sealants, cosmetic silicones, and high-performance compounds. With decades of expertise, CHT supplies industries worldwide, from automotive and electronics to medical devices and food processing.

CHT traditionally supplies industrial-sized packaging (drums, IBCs), but Siliconesandmore.com makes these premium materials accessible to smaller users, labs, and development teams by offering smaller packages and samples. We are gradually expanding our CHT range with new product lines and specialized materials.

Benefits of CHT at Siliconesandmore:

• Fast delivery from the Netherlands
• Smaller packages and samples available
• Professional technical support
• Phased expansion with new CHT products
• Scale-up to bulk possible for production
