Thermoplastic Compounding

PolyVisions Takes a Leap in Thermoplastic Compounding

Thermoplastic compounding allows manufacturers to turn plastic material into different useful things. While there are a number of plastic polymer materials available, the number of end user plastic products seems endless. We see and use more than a dozen plastics every single day. Thermoplastic compounders are responsible for maximizing the use of thermoplastics by turning them into every useful form possible.

Thermoplastic compounding enables basic polymers to work better. It’s a process whereby base polymers are combined with other materials to enable the base material to behave in a different way. Compounding improves the properties of the base polymers by the addition of other materials to them.

How does plastic compounding work?

The process of thermoplastic compounding is done in what is called an extrusion machine. PolyVisions Inc., a leading choice in plastic compounders, specifically employs twin screw extruders. This type of machine is made of heated screws that melts the substances first then blends and propels them.

The first step involves placing the base polymer into the extruder. It is heated, melted and move in the extruder barrel. PolyVisions also add other substances called additives which are responsible for either enhancing or modifying the base polymer’s behavior. They are mixed with the polymer in the barrel. When the materials reach the barrel’s end, it is ready for packing.

In addition to additives, thermoplastic compounders may also use recycled materials that come in the form of shavings and chips. Other substances called modifiers may also be included in the process to enhance the characteristics of the end product further. Plastic compounders typically use polyethylene and polypropylene as base polymers. PolyVisions has worked with other polymers including polyethylene terephthalate, nylon, thermoplastic elastomers and polycarbonate.

What are additives really for?

The list of additives include fillers, nucleating agents, elastomers, lubricants, flame retardants, carbon nano particles, glass fibers and pigments among many others. These additives can make a huge difference to the properties of the end product. The mixture of base polymers and additives can result to changes or enhancements in the end product’s impact strength, color, cold and heat resistance, flexibility, tensile strength, electrical conductivity, lubricity, etc. Over the years, PolyVisions has come up with incredible polymer formulations that have made huge differences in their clients’ businesses.

The PolyVision Solution

PolyVisions Inc. does things differently. What the company does involves more than your run-of-the-mill thermoplastic compounding. They can also do what is called reactive compounding. It is a process that initiates chemical reactions during extrusion. The end result is a product referred to as grafted polymer.

Rather than simply blending the substances, the materials are actually bonded. It occurs at the molecular level. It results in the transformation of the base material’s properties.

While adding desirable qualities to the final product, reactive extrusion is also capable of maintaining the polymer’s mechanical and thermal properties. This technique allows PolyVisions Inc. to create uniquely engineered products that are highly useful to various industries from the food processing, food packaging, transportation, healthcare, wire and cable.
