Difference between silicone LED strip and PVC LED strip

Feb 22, 2022

No	Feature description	Performance of silicone LED strip	Performance of PVC LED strip
1	Environmental protection characteristics	Environmental protection of materials:1. No smell during production;2. There is no thick smoke and pungent gas during combustion,no dripping.	Materials containing halogen are not environmentally friendly:1. There is severe and pungent gas HCl during production, which is harmful to the health of production employees;2. During combustion, there are thick smoke, pungent gas and dripping to cause secondary combustion.
2	Anti UV characteristics	Outdoor use for more than three years without yellowing, light transmission unchanged, color temperature does not drift.	After half a year of outdoor use, it turns yellow seriously, the light transmittance decreases by more than 30%, and the color temperature drifts seriously.
3	Weather resistance	Excellent weather resistance:- 60 degrees to 200 degrees invisible change.	Poor weather resistance: After half a year of outdoor use, it began to turn yellow, crack and fragile, and began to deform at more than 80 degrees; It starts to harden around minus 10 degrees and is difficult to install.
4	Optics	1. The refractive index of silica gel is 1.59, which is convenient for light diffusion and increases the beam angle; 2. The light transmittance of silica gel is more than 95%; 3. It does not affect the color rendering index.	1. PVC refractive index 1.49; 2. The maximum transmittance of PVC is about 90%; 3. Due to UV yellowing / HCl volatilization, the color rendering index will be greatly reduced after corroding the lamp beads.
5	Corrosion lamp bead	No corrosion	Volatile HCl gas containing halogen corrodes lamp beads, causing color temperature drift, dead lamp, etc.
6	Corrosion resistance	Excellent corrosion resistance	Chemical reaction with strong base
7	Machining	Cold extrusion and hot forming, easy to process and form	PVC hot processing and cold forming, which is more difficult.
8	Warranty	Above 3 years	One year
