One perplexing problem that occasionally arises during long extrusion and calendering runs, especially with opaque, pigmented or filled compounds, is plateout – a term used to describe the buildup or deposit of incompatible material on the screw, in the die, on embossing rolls,roll take-up equipment or sizing sleeves. In time this deposit affects the surface finish of […]
PVC (polyvinyl chloride) is a type of plastic that finds extensive residential, commercial, industrial and military use. Comprising a wide range of materials and applications, including pipes, footwear and floor coverings, PVC plastic is used globally for its versatility, stability and good chemical and physical properties. Flexible PVC plastic compounds are used in communication wire […]
At first glance, PVC and CPVC pipe look the same, but they aren’t. Although they are both a type of plastic plumbing pipe, they vary in composition and outside diameter. For this reason, you cannot simply join the two types of plastic with a coupling. You can, however, solvent-weld a special fitting designed to compensate […]
There are many things to take into account when considering the types of pipes to use in a building project. Cost is a factor, but the use and the location of the pipes will also help determine what type of piping will be best.

The use of PVC compounds in medical device manufacture for more than 50 years has demonstrated its great ability to satisfy the demanding requirements of the medical health care industry.
PVC was originally developed as replacements for natural rubber and glass. Medical devices made from these traditional materials demanded cleaning and re-sterilisation before re-use. The low […]
PVC, or polyvinyl chloride, pipes are soft plastic pipes commonly used in a variety of plumbing applications. They are readily available at most hardware stores in an array of sizes. The size of a PVC pipe is closest to the pipe’s inside diameter (ID). The ID of a pipe varies, however, based on the wall […]
Within the depths of the Earth, several minerals have been discovered. Scientists and chemists continue to explore the vast dimensions of our world to find something useful and beneficial to humanity. One of the discovered minerals is titanium dioxide. Titanium dioxide occurs naturally within the soils of the Earth. It has a whitish and opaque […]
PVC is a great material for plumbing and other projects as well. It’s easy to cut and glue and is inexpensive, and even a novice do-it-yourselfer can make repairs with it. Here is a PVC primer for those who need to know the basics.
