Titanium - Corrosive Media

Aeration improves the resistance of titanium in most of these nonoxidizing acid solutions. In the case of formic acid, it reduces the corrosion rates to very low values. Unalloyed titanium corrodes at a very low rate in boiling 0.3 percent sulphamic acid and at a rate of over 100 mpy (2.54 mm/y) in 0.7 percent boiling sulphamic acid.

What is High Density Polyethylene Sheet? - HDPE Facts

Resistance: Not only does HDPE sheet feature a high chemical and impact resistance, but it also is resistant to rotting, insects, mildew and mold. Weatherability: HDPE sheet is often used for outdoor appliions as it can stand some of the most extreme weather.

How Does Temperature Affect Metal? | Sciencing

2018/4/13· A higher temperature increases the electrical resistance of a metal, and a lower temperature reduces it. Heated metal undergoes thermal expansion and increases in volume. Increasing the temperature of a metal can cause it to undergo allotropic phase transformation, which alters the orientation of its constituent atoms and changes its properties.

Polyphenyl ether - Wikipedia

Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages. Commercial phenyl ether polymers belong to two chemical classes: polyphenyl ethers (PPEs) and polyphenylene oxides (PPOs). The phenoxy groups in the former class of polymers do not contain any substituents
