UV Resistance
The suns rays are very harsh and will produce a
yellowing effect on vinyl flaps. Some of these flaps are heavily
tinted to prevent this yellowing from showing (we suspect).
Besides yellowing, vinyl is weakened by prolonged exposure to
ultra-violet. |
The Endura Flap
material is specially treated with a powerful UV retardant.
And it's Not vinyl.
In intense test chamber exposure equivalent to 2
years of Florida sunlight, no yellowing or degradation of the Endura
flap material occurred.
At the same time we tested the Endura material, we
tested vinyl flap samples from every leading pet door manufacturer.
In each case, there was significant yellowing, crackling and
degradation of the material. |
