High thickness and large-diameter pipes: how to avoid sag in pipe extrusion

Avoid sagging effect in pipe extrusion

The increased usage of large- diameter pipes, from 630mm to 1,200mm, across various applications has encouraged the development of PE100 materials suitable for large-diameter pipes to prevent problems during extrusion, like sagging.

Maintaining dimensions within specifications is problematic for the extrusion of large-diameter thick-wall HDPE pipes (> 75mm wall) due to sag caused by insufficient resin melt strength.

PVC or iron?

Why should we choose PVC pipes over iron

Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. It is an odorless, brittle thermoplastic, which is lightweight and easy to handle. PVC takes less non-renewable fossil fuel to make than any other commodity plastic, compared to plastics such as PE, PP, PET and PS, which are totally dependent on oil or gas, thereby favoring the production of P...

Calcium Carbonate: when is it an advantage?

Use of CaCO3 does not result in cost reduction without sacrificing quality and damage to process equipment

In PVC products, CaCO3 is added for two reasons: to reduce the cost and to provide functional properties. Viscosity of PVC compound is important from a processing point of view. It increases with the addition of filler because CaCO3 does not melt during processing. From a product application perspective, elastic modulus is a function of particle shape, while impact stren...

Converting natural gas to plastic

The term "plastic" suggests one material, but there are actually hundreds of different plastic polymers

Polymerization occurs when a chemical reaction causes molecules to react together to form polymer chains. These polymer chains can be engineered to control the specific physical properties of the resulting plastic resin, thus allowing the product to be designed for many different uses. For example, some plastic products may require extra strength, some require maximum fl...
