Standard wall thickness: higher mechanical strength than thin-walled, more flexible than medium-walled. 4:1 covers a wide range of applications, with high contact pressure. The thermoplastic high-performance inner adhesive achieves sealing values far exceeding the usual requirements in the automotive industry. It reliably prevents electrochemical corrosion. Good mechanical strength. Resistant to typical automotive fluids. The transparent outer layer with black inner adhesive allows for subsequent visual inspection. Halogen-free. SA47-LA offers excellent protection against moisture and corrosion for all electrical connections and is resistant to typical automotive oils and fluids. The use of a black inner adhesive combined with a transparent shrink tube enables subsequent visual inspection of the shrinkage process. Air inclusions and suboptimal adhesive application can thus still be detected and assessed later.
