Description
About Shin-Etsu KE-20 Silicone Rubber Compound
OVERVIEW:
Shin-Etsu KE-20 is a heat-cure, high-consistency silicone rubber (HCR) compound designed for molding and extrusion applications. It offers a balanced combination of mechanical strength, flexibility, and thermal stability. KE-20 is suitable for manufacturing a wide range of silicone rubber parts used in automotive, electrical, consumer, and industrial products where durability and environmental resistance are required.
KEY FEATURES:
Thermal Stability
Performs effectively across a broad temperature range, typically from -60°C to +200°C, maintaining mechanical properties under thermal cycling.
Excellent Flexibility and Elasticity
Provides long-lasting flexibility and resilience, supporting applications requiring repeated mechanical stress or deformation.
Good Processability
Suitable for standard compression molding, transfer molding, and extrusion processes, allowing ease of manufacturing.
Weather and UV Resistance
Offers excellent resistance to outdoor weathering, ozone, and ultraviolet (UV) radiation, contributing to product longevity in exposed environments.
Electrical Insulation Properties
Provides good dielectric performance, supporting use in insulating components for electrical and electronic applications.
APPLICATIONS:
-
Automotive Components – Used in gaskets, seals, hoses, and vibration dampers requiring long-term durability and heat resistance.
-
Electrical Insulators – Applied in molded parts for insulating and protecting electrical assemblies.
-
Consumer Products – Suitable for various molded silicone rubber items such as kitchenware, baby products, and wearables.
-
Industrial Equipment – Used in seals, gaskets, and flexible components exposed to mechanical stress and environmental conditions.
-
General Rubber Goods – Ideal for custom-molded parts requiring a combination of elasticity, durability, and weather resistance.
PACKAGING:
Shin-Etsu KE-20 is typically supplied in blocks or sheets (commonly 20kg cartons) suitable for processing by molding or extrusion equipment. Packaging may vary based on region and distributor.
INSTRUCTIONS FOR USE:
-
Processing: Designed for use with conventional silicone rubber molding and extrusion equipment. Curing conditions (temperature and time) should be adjusted based on part design and processing requirements.
-
Post-Cure: Post-curing may be recommended to achieve optimal mechanical and electrical properties, especially for components used in demanding environments.
-
Storage: Store in a cool, dry place to maintain compound stability before use.
