There are two kinds of Teflon insulating sleeves, one is regular pipe (regular is a wall thickness, other wall thickness can be produced according to specifications), and the other is capillary, which can be divided into S-type, T-type and L-type according to the wall thickness and voltage resistance level of the product.
Teflon insulation sleeve has excellent dielectric properties and chemical corrosion resistance, high temperature resistance, high pressure resistance, non-absorbent, non-sticky, non-conductive, low friction coefficient and non-aging properties. Widely used in transformers, electronic appliances, communication equipment, chemical fluids, machinery manufacturing, medical equipment and automotive aerospace and other fields.

3. High Temperature Heat Shrink Sleeve Manufacturers
High temperature resistant heat shrinkable sleeve is classified, including ordinary heat shrinkable tube, Teflon heat shrinkable tube, FEP transparent heat shrinkable tube and PFA transparent heat shrinkable tube. Their temperature resistance levels are different.
High temperature heat shrinkable tube has the advantages of high temperature resistance, high mechanical strength, good chemical resistance, etc. It is widely used in cable insulation protection, insulation treatment or stress relief at the end or connection, coating and insulation protection of wire processing, solder joint protection, coating of electronic components, insulation protection of resistors and capacitors, rust prevention and corrosion prevention treatment of metal products, wire marking or color marking, etc.
High temperature heat shrinkable sleeve can be divided into 125 ℃ heat shrinkable tube, 135 ℃ heat shrinkable tube, 150 ℃ heat shrinkable tube, 175 ℃ heat shrinkable tube, 200 ℃ heat shrinkable tube, 260 ℃ heat shrinkable tube and medical heat shrinkable tube according to temperature grade and service environment.
The 200 ℃ heat shrinkable tube has excellent high and low temperature resistance, oil resistance and chemical reagent resistance, and is especially suitable for places requiring heat resistance (such as electrical and hydraulic systems near aircraft or automobile engines or fuel tanks) and environments requiring chemical solvent resistance. The 200 ℃ heat shrinkable tube is suitable for insulation protection and stress relief of cables and harnesses in these environments, and protects electronic and electrical equipment from damage.
