Preguntas Frecuentes (FAQ)

Q: What is the shrink ratio of these heat shrink sleeves and how does it affect choosing the right size for a wire?
A: These heat shrink sleeves have a 2:1 shrink ratio. This means that after applying heat, the sleeve's diameter will shrink to half its original diameter. To choose the right size, measure the wire's diameter before applying the sleeve and pick a sleeve with an initial diameter that is double that measurement. For example, for a wire 3mm in diameter, you would need a sleeve with an initial diameter of 6mm.

Q: What is the recommended temperature range for applying heat to these heat shrink sleeves and which heating methods are best to avoid damaging the wire or the sleeve?
A: The recommended temperature range for applying heat to these heat shrink sleeves is usually between 70°C and 120°C. The most suitable heating methods are a heat gun or a hot-air torch, keeping a safe distance to avoid burning the sleeve or the wire. Avoid direct flames, as they can damage the wire insulation and the heat shrink sleeve. It is important to apply heat evenly to ensure full shrinkage.

Q: What material are these heat shrink sleeves made of (PVC) and what level of protection do they offer against abrasion, chemicals and moisture in FPV applications?
A: These heat shrink sleeves are made of PVC (polyvinyl chloride). They offer basic protection against abrasion, moisture and some mild chemicals. However, for FPV applications that require greater resistance, especially in harsh environments, keep in mind that PVC is not as durable as other materials such as polyolefin. For superior protection, especially against stronger chemicals or extreme temperatures, we recommend using polyolefin heat shrink sleeves.
