Applications for General Purpose Grade Silicone

Construction and building

  • Sealing joints: Used around windows, doors, and building joints to create waterproof and weatherproof seals. 
  • Adhesives: Functions as an adhesive for materials like glass, metal, aluminum, and UPVC. 
  • Weatherproofing: Ideal for exterior applications such as siding, trim, baseboards, gutters, and vents. 
  • Sanitary applications: Prevents mold and mildew growth in kitchens and bathrooms. 
  • General sealing: Used around pipes and wires to seal gaps and prevent air or water leakage. 

Manufacturing and industry

  • Seals and gaskets: Fabricated into seals and gaskets for vehicles and industrial equipment. 
  • Tubing: Used to create tubing for the food and pharmaceutical industries, often meeting specific regulatory standards. 
  • Molded parts: Suitable for creating complex extruded and molded parts. 

Other applications

  • Flexible joints: Used in applications like cold storage and containers. 
  • Electrical insulation: Provides excellent electrical insulation properties. 
  • General purpose sealant: A versatile sealant for a wide range of surfaces, from glass and ceramics to painted surfaces. 

Additional Information

General purpose grade silicone is a versatile, cost-effective material used across a wide range of industrial and consumer applications. It offers good thermal stability, flexibility, and resistance to water, ozone, and UV radiation. Typically available in solid, liquid, or foam forms, this silicone grade is suitable for non-critical sealing, gasketing, insulating, and cushioning tasks. While it may not meet the stringent requirements of medical, aerospace, or food-grade applications, it performs reliably in many standard environments. General purpose silicone is also easy to process via extrusion, molding, or coating, making it a practical choice for everyday manufacturing and maintenance needs.

General purpose grade silicone is a type of silicone rubber that’s formulated for a wide range of standard, non-specialized applications. It’s valued for its balance of performance, affordability, and versatility. For assistance with material selection, contact ElastaPro.
