SRT silicone rubber shrink tubing is designed for insulating, protecting and covering electronic components with special requirements. Its key advantage over other tubing is softness, with temperature resistance up to 200 °C.
Features:
■ High-temperature and voltage resistant, flame-retardant, soft; SGS tested, RoHS compliant
■ Shrink temperature: 90–170 °C
■ Operating temperature: −50 to 200 °C
■ Shrink ratio: 1.7:1
Applications: protection of electronic components, resistors and capacitors, aerospace, electrical appliances, lighting and medical devices.
