Please explain the Inside Diameter, Expanded (IDe) and the Inside Diameter, Recovered (IDr)?

To select the appropriate Heat Shrink Tubing Solutions, choose an expanded inside diameter (IDe) that easily slides over the largest dimension of the wire bundle, targeting about 10% oversizing. Forcing the tubing can cause damage and may require the next available size if interference occurs. For the recovered inside diameter (IDr), select a size smaller than the wire bundle’s diameter, aiming for about 10% undersizing, to ensure an effective seal, as an IDr larger than the bundle will not seal properly.

What is the importance of Splice Design when using Heat Shrink Tubing Solutions?

Splicing wires to form common circuits is an effective way to reduce cost, weight, and complexity, but improper splices can create costly failure points. Adhesive-lined Heat Shrink Tubing Solutions help seal out moisture and contaminants, preventing premature failure. For more complex splices, design considerations such as total wire count, balance, and cross-sectional area must be carefully evaluated to ensure reliability.

What is the difference between single wall and dual wall heat shrink tubing?

Our Heat Shrink Tubing Solutions come in two main types. Single wall tubing consists of a single layer of material and provides good insulation and abrasion resistance. Dual wall tubing, also known as adhesive-lined tubing, has an inner layer of adhesive that melts and seals the connection, providing a waterproof and corrosion-proof barrier.

What are some tips for proper and consistent application of Heat Shrink Tubing Solutions?

Proper application of Heat Shrink Tubing Solutions requires controlled temperature and time to effectively shrink the tubing and ensure adhesive flow, while avoiding overheating that can cause burning or adhesive dripping. Acceptable heat sources include heat guns, ovens, or specialized HST processing machines. Direct open flames should not be used, and all equipment must be properly maintained and calibrated, following the manufacturer’s instructions for consistent outcomes.

Are your Heat Shrink Tubing Solutions RoHS compliant?

Yes, Eurotech offers numerous Heat Shrink Tubing Solutions that are RoHS compliant, meaning they are free of hazardous substances. Additionally, we have models that meet standards for UL, Halogen Free, REACH, ELV, and SAE.
