Advantages of Huashida heat shrinkable sleeve
A. Heat shrinkable sleeve base material for the production of raw materials, raw material production from the outside looking highly than other manufacturers bright. Other manufacturers of raw materials accounted for 50% -60% recycled materials accounted for 50% of the
B. Stronger baking resistance, lap joints do not crack, convenient construction
C. My company's hot melt adhesive using EVA hot melt adhesive, adhesive strength, high peel strength glue
D. Shrinkage speed
E. Good sealing performance
F. Qingdao Huashida production of heat shrinkable tape (sets), the use of adhesive are purchased from the United States DuPont, Japan Sumitomo, South Korea, Hanwha and other international brands, EVA content of 28%!
Feature
1.Fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life, convenient transportation and fast construction.
2. 3Layer Fiber
reinforced PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back, a middle layer of fiber and special heat melt adhesive an. The 3 layer reinforced sleeve gives better shrink ratio, and better strength. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.
Application area:
It is mainly used for Hollow wall spiral pipe, corrugated pipe and metal reinforced corrugated spiral pipe etc.
TEST PROCEDURE
1. Clean the steel pipe and heat it by fire till over 80 ºC
2. Paint the steel pipe with Primer (mixed with A&B)
3. Fire heat the heat shrink sleeve, be attention to start heating from middle of the sleeve, but act from up and down, and gradually move from middle to two sides of sleeve, in order to drive air out of the sleeve, after finish heating, the good result is that there is about 1-2mm hot adhesive melt at the edge of sleeve.
TEST RESULT
1. Test result after cooling about 40 minutes.
Peel strength to primer is over 100N per 2cm(till the end of the spring balance). at 30.7ºC
Co-adhesive: Half-half.
2. Test result after cooling about 24hours.
Peel strength to primer is over 172N per 2cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
3. 2. Test result after cooling about 24hours.
Peel strength to primer is over 9.2kg/90N per 1cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
