A long chain silicone gum with controlled vinyl level is combined with fumed, precipitated silica as reinforcing filler along with various other materials and additives to create special properties. Once you cure the compounds at high temperature (100~200 ºC) after mixing with catalysts it becomes HTV silicone rubber. The molding process can be compression, extrusion, etc. Main applications: Baby products: Baby nipple, baby bib, etc. Medical products: catheter and negative pressure drainage ball. Kitchen products: bake ware, silicone scoop, etc. Industry product:: Key button, sealing rings and small parts. Electric product: cable accessories, insulator, etc. Sports product: swim cap, goggle, etc.
1. 1:1 addition type, good adhesive strength and self-healing 2. High elongation, excellent flexibility for mechanical stress relieving 3. Low oil penetration after cured, good anti-poisoning property 4. Good dielectric in high temperature for high voltage protection 5. Excellent aging resistance and weatherability 6. Excellent waterproof, corrosion prevention, moisture proof and chemical media resistance Used for encapsulation of various modules, semi-conductor, IGBT, automotive ECU module, IC chip, weighing sensor, waterproof connector.
