There are two commonly used heat-shrinkable tubes with adhesive: double-wall heat-shrinkable tube referred to as double-wall tube, medium-wall heat-shrinkable tube referred to as medium-wall tube, so now let's talk about the differences between them. Generally speaking, double-wall heat shrinkable tube and medium-wall heat shrinkable tube is similar, there are the following four differences:
First, the diameter is different: the caliber of the wall heat shrink tube is larger than the double-wall heat shrink tube, the softness is relatively small; double-wall heat shrink tube caliber is small, sealing performance is very good.
Second, the glue coating process is different. Double-walled heat-shrinkable tube extrusion at the same time, the thickness of the glue layer is uniform, visible to the naked eye obviously two layers. The middle wall heat shrink tube glue coating method is divided into straight coating and spiral coating glue. Straight coating glue inner wall is a straight stripe, spiral coating glue inner wall is a circular ring.
Third, the high temperature resistance is different. Mid-wall heat shrink tube continuous use temperature: -55 ℃ ~ 105 ℃, the minimum starting shrinkage temperature: 80 ℃, heat shrink tube minimum complete shrinkage temperature: 120 ℃, and double-wall heat shrink tube is basically the same, but the highest use temperature up to 125 ℃, and heat shrink mid-wall heat shrink tube at most in 105 ℃ continuous work. In fact, at the highest temperature, the service life of the material will be greatly shortened.
Fourth, the application of different aspects: double-walled heat-shrinkable tube is suitable for electronic equipment wiring waterproof, leak-proof, water pumps and submersible pumps wiring waterproof, underwater lighting, automotive fuel lines, advanced wiring harnesses and other occasions. Medium wall heat shrinkable tube is suitable for small diameter steel pipe, stainless steel and other hard objects of external corrosion, reinforcement, such as sound pipe, concrete buried steel pipe connection waterproof, corrosion.
