Explosion-proof lam LED photodiffusion heat shrink tube is made of household materials, excellent transparency, good heat dissipation effect, insulation, protect glass from breaking.
1, White LED heat shrink tube can homogenize point light to area light.
2, light transmittance can be up to 85-93%, haze 95-99%, customizable.
3, ROHS compliant, mercury-free, UV-resistant, energy-saving and low carbon.
4, Applicable to t5, T6, T8, T10, t12 LED lights.
Shrinkage temperature 60℃
125℃ final shrink temperature
Working temperature: -55℃~125℃.
When cutting the tube, the length of the glass lamps is increased by 5mm, the glass lamps that have been washed with alcohol and dried are installed on the heat shrink tube for cutting. Place them in a tunnel oven at a constant temperature of 75-85℃ to shrink.
After 1-2 minutes, check whether the pipe shrinks. if not, let them decrease sequentially. if the temperature is a little high, the heat shrink tube will form crystalline and black spots. trim them with a craft knife after they are already cool, proceed to the next step to install if there is no problem.

The transmittance of the same film tube changes to 2% when 2 and 60 hours are below 10,000 hours. (the product cannot be used above 90s, and the transmittance is reduced by 5% due to the crystallization of the material). |
