PP Waxes with Unique & Customizable Technical Properties
GreenMantra’s new PP waxes are among the high-value products from waste plastics it makes.
At the very least, I always find it reassuring when we hear of any new plastics recycling effort. But, it’s downright inspirational when that effort is effectively converting waste plastics to something of high value. Such is the case with GreenMantra Technologies of Brantford, Canada, a reportedly rapidly growing clean technology company that produces high-value polymer products from waste plastics.
GreenMantra utilizes a proprietary thermos-catalytic system and patented process to cost-effectively convert and “up-cycle” waste plastics, including hard-to-recycle materials such as grocery bags and film, into high-value waxes and other specialty chemicals. These materials have a broad range of application in the plastics processing, coatings, adhesives, roofing and paving industries.
The company has just announced the development of a new line of synthetic PP waxes that are said to provide a unique range of technical properties previously not available in the market. New Ceranovus PP waxes, produced from post-industrial plastic waste and post-consumer recycled plastics such as yogurt containers and bottle caps, can be tailored to specific end-use applications. Says director of research & business development Domenic DiMondo:
“We are able to customize these new polypropylene waxes in ways that are simply not possible with traditional waxes. This enables us to provide waxes with specific technical properties designed for individual customers, depending on their exact needs.”
In plastics processing and color masterbatches, these waxes reportedly can improve throughput, reduce breaks in product forming, and enhance dispersion of additives. For hot-melt adhesives manufacturers, these waxes can provide flexibility to formulation properties such as adhesive open and set times and boost high-temperature performance. Ceranovus waxes can also be used to stabilize or increase the softening point of commercial, residential or peel-and-stick roofing products while decreasing penetration in desired formulations. They can also improve compound stability and impact resistance.
The new Ceranovus A series PP waxes are designed for applications that are not color specific, while Ceranovus G series PP waxes are for applications that are color sensitive. They complement GreenMantra’s existing range of PE waxes that also produced from waste plastics.
In addition to being made from 100% recycled materials, Ceranovus waxes have received third-party certifications for recycled content. This provides the company’s customers with transparent documentation to qualify for environmental product standards and green building requirements like the U.S. Green Building Council’s LEED certification.
Good news was there if you knew where to look for it—in the pages of Plastics Technology magazine or right here on our website. Here’s a review of headlines you can feel good about.
