PE transparent protective film and low viscosity transparent protective film 
 I. Main performance: 
 1. Paste test: easy to paste on the surface, without leaving adhesive residue: a. 90-degree bend with an object, not broken, do not fall off; b. Zi Baosuo test of tear film after the film surface residue. 
 2 load test: 360h25 degrees -50 degrees to withstand / SPCM2 load, peel off the track after the glue is not surface residue. 
 3 UV-resistant aging test: at 50 degrees under the conditions, 300w 60h after exposure to ultraviolet light does not crack, no distortion, no residual traces of the surface removed. 
 4 resistance to heat aging test: 60 degrees +80% = 240H, after not fall off, peel off without leaving adhesive residue, non-corrosive surface. 
 II. Paste Requirements: No need to dust the surface to be posted no oil. 
 Three main technical parameters: 
 1 sticky: the sticky --- Backing: polyethylene --- thickness :0.03-0 .15 mm --- peel strength (KN / M) :0.06-0 .07 --- Tensile strength :600-800 - Fracture elongation :150 -180-- temperature resistance: ≤ 60 degrees; 
 2. Hyperviscosity --- Backing: polyethylene --- Thickness :0.05-0 .13 mm --- peel strength (KN / M) :0.08-0 .11 --- Tensile strength :600-1000 - elongation rate :180-200 - Temperature resistance: less than or equal to 60 degrees; 
 3 Viscosity: special high viscosity --- Backing: polyethylene --- thickness :0.05-0 .13 mm --- peel strength (KN / M) :0.22-0 .32 --- Tensile strength :600 -1100-- elongation :150-220 - Temperature resistance: less than or equal to 60 degrees;
