Harvel s corzan compounds used in the manufacture of rigid cpvc pipe contains at least 2 titanium dioxide ti02.
Uv stabilized pvc pipe.
Uv resistant materials by nature resists uv.
They are available for engineering and industrial piping projects because cpvc can withstand a greater array of high temperatures.
The sun emits visible and non visible radiation.
Also known as schedule 40 pipe it s typically used in low pressure residential and commercial plumbing and water supply applications.
These upvc pipes are joined with.
Because pvc is sensitive to uv light if it is used above ground it should contain stabilizers and uv inhibitors and may require painting with a water based latex paint.
Due to its rigidity pvc pipe cannot be coiled and has to be transported in rigid segments.
Uv stabilized means they have added a stabilizer to the resin to allow it to protect the substance from the long term degradation from uv light.
In this bulletin we re going to explore the effect sunlight exposure has on pvc pipe conduit and fittings.
Like many other substances pvc plastics are affected by exposure to uv radiation.
That means the normally white pvc will start to turn a brownish color.
Pipe is pvc which has good corrosion resistance.
Connect to unthreaded female socket connect fittings using a pvc primer.
There are some types of pvc pipe and fittings that are treated to protect against uv rays furniture grade pvc for example.
It should be noted that harvel s standard formulation of pvc compound h707 used in the manufacture of our rigid pipe contains 1 1 2 titanium dioxide ti02 a natural uv inhibitor.
Made with an additive that protects against the damaging effects of ultraviolet light this pipe won t degrade in outdoor environments.
Lead free uv stabilized pipes and fittings and upvc threaded pipes.
It is hard to believe that they are not completely resistant to uv rays.
Basically pvc pipe exposed to sunlight can discolor and become hardened or slightly more brittle on the outer surface of the pipe but the pipe itself has no adverse changes with installation and.
The pvc pipe association s handbook of pvc pipe states that the exposure of uv radiation can also result in a change in the pipe s surface color.
For evergreen everlasting and ever powering tomorrow contact us now.
All the color change means is that the very outer layer of the pipe is altered.
This is only true of untreated pvc after prolonged uv exposure.
Uv stabilizers work by absorbing or screening out uv radiation and preventing damage.
What is the difference between uv stabilized and uv resistant.
Cpvc and pvc pipes are made out of very strong and versatile materials.
