◪Vulcanization Conditions
RTV silicone rubber is vulcanized at room temperature (usually around 20℃). This allows it to form a strong tubber without the need for high-temperature curing.
◪Hardness Range
RTV silicone rubber can be prepared in materials of varying hardnesses, typically ranging from very soft (e.g. 10 Shore A) to relatively hard materials (e.g. 70 Shore A)
◪Rubber Elasticity
HTV silicone rubber retaind rubber elasticity after vulcanization and has good tensile and tear strength. This makes it useful in applications where elasticity and flexibility are required.
◪High and Low Temperature Resistance
RTV silicone rubber generally exhibits good resistance to high and low temperatures. It maintains elasticity and physical properties over a wide temperature range.
◪Chemical Stability
Silicone rubber is chemically stable to a certain chemicals still need to be used with caution.
◪Elactrical Insulaton Properties
RTV silicone rubber is typically an electrically insulating material used in electronic and electrical applications.
◪Transparency
RTV silicone rubber can be prepared in clear or translucent forms, making it useful in some visual applications.
◪UV Resistance
It usually has some UV resistance, making it suitable for outdoor and sun-exposed applications.
◪Biocompatibility
Some rtv silicone rubbers have good biocompatibility and are therefore widely used in medical devices and medical fields.
◪Liquid Silicone Rubber
Liquid silicone rubber (LSR) versions of rtv silicone rubber are available for injection molding and offer excellent flow and processing properties.
