We have noticed a growing trend online for our competitors to boast a thicker product as a superior product.
We are going to dispel that myth.
The thickest vinyl/PVC you will find on the market is typically found in PVC pipe. PVC pipe can be in excess of 1/4 inch thick. If you have ever looked at a PVC pipe that has been left outside for a year, you will notice that it has yellowed or turned brittle.
That is due to the lack of impact modifiers and TI02/Titanium Dioxide.
Just because a vinyl fence profile is thick does not mean that it will hold up to the elements.
Vinyl/PVC strength is measured by the Ultimate tensile strength (UTS), UTS is the maximum stress that a material can withstand while being stretched or pulled before necking. Necking is when the specimen’s cross-section starts to significantly contract.
Tensile strength is the opposite of compressive strength and the values can be quite different. The UTS is usually found by performing a tensile test and recording the stress versus strain; the highest point of the stress-strain curve is the UTS. It is an intensive property; therefore its value does not depend on the size of the test specimen. However, it is dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
A Vinyl/PVC product can be made stronger utilizing the proper amount of ultraviolet inhibitors and TI02/Titanium Dioxide which acts as a sun block, plus impact modifiers which provide superior strength, impact resistance and flexibility.
The extrusion process is another pivotal difference in separating a quality product from a lesser grade vinyl.
Not all vinyl has the same additives in order to make it strong. Some salespeople like to brag about how thick their vinyl profiles are, but really thickness is only a small part of the equation. Just because a product is thick it does not mean it will stand up. So many things go into the process of making a vinyl profile and turning it into a fence. Things such as the quality of chemicals and supply chain (so you have exactly the same raw product to start with), the speed a profile is run at, even the particle size of certain additives all contribute to the quality of vinyl you will end up with.
