HEAT SHRINK TUBING FOR AUTOMOTIVE APPLICATIONS TE AUTOMOTIVE /// WHITE PAPER 5 Under bonnet cable protection Underbonnet higher temperatures and exposure to agresive fluids place additional demands on the materials used to protect cables in these harsh environments. Products will require to offer long term heat resistance and withstand inmersion in diesel fuels, hydraulic fluids and lubricating oils. Flexibility and abrasion resistance are ideal for the protection of electrical cables or similar components in these environments. 2:1 +175° C +150° C -55° C 2:1 +175° C Protection: Chemical / Mechanical Abrasion Application Challenge facing manufacturers Products: Features + Benefits Application Tooling Vehicle engine compartments are becoming ever more crowded and compact, often forcing cooling hoses to be routed in close proximity to high temperature engine components and under-bonnet parts. This makes hoses highly vulnerable to abrasion and chafing. This same space considerations may require hoses to be designed with sharp bends and other radical shapes, making difficult for manufacturers to fit protective sleeves where damage is likely to occur. An added complica- tion is the effect that any over-protection may have on its surrounding components. Contacts between two hoses or a hose and a harness are hard to avoid. Where over-protection is used to alleviate this problem it needs to be non-abrasive itself and protect both components. DR-25 • Excellent resistance to fluids FRAG • Good long term heat resistance • Flexible and abrasion resistant +125° C -40° C 2:1 +110° C +80° C -40° C HFT 5000 • Highly flexible woven fabric construc- tion for easy installation onto bent hoses • Excellent mechanical and abrasion protection • Extremely tough meeting even demanding automotive abrasion specifications • Grips sustrates without additional fixing • Resists harsh engine compartment environments • Safe installation with no hot knife cutting equipment required • Resists hose pulsing effects • Protect only where protection is needed - minimizing cost • Halogen free Metal brake and fuel lines, particularly those routed underneath vehicle floorpans and near suspension components, are exposed to sub- stantial mechanical damage from flying stones and gravel. This damage can compromise the integrity of the pipe and abrade the protective coating surrounding the pipe allowing corro- sion to set in. Auto manufacturers must find cost-effective ways of protecting these pipes to meet ever-increasing standards of vehicle raliability and safety.
