Integrating Specialty Additives for Custom Plastic Sheet Formulations

Posted by Natalie K. MacVarish on October 12, 2018
As a custom sheet extrusion company, we offer myriad options to our customers in regards to how they can customize their order. At the most basic level, customers can select from a range of products in different polymers and customize their size, gauge and surface. Taking customization a step further, customers can also choose from a selection of “house” colorants or have the sheet color matched to any color under the sun. In addition to this, Impact Plastics also has the ability to integrate specialty additives into the plastic sheet that further enhance the properties of the material. These specialty additives are added at the extrusion level through a sophisticated blending system that homogeneously blends the additive into the sheet, creating a truly custom formulation for our customers.

Environmental Advantages of Using Calcium Carbonate in Plastics

Posted by Natalie K. MacVarish on August 17, 2018

Have you ever thought about how much plastic products are integrated into your everyday life? If you stop to think about it, chances are you touch something made from plastic every day. For decades plastic materials have helped provide us with products that help us live a clean, healthy and efficient lifestyle and are used in a vast range of products from plastic bottles, cups and plates, to composite furniture and building products, and even in automotive components.

How to Choose Mineral Filler Type and Level for Thermoforming

Posted by Natalie K. MacVarish on December 1, 2017

Calcium carbonate (CaCO3) and talc are two widely used mineral fillers in the plastics industry, and their use in rigid packaging has increased significantly over the years. Once thought of simply as resin extenders, the addition of these mineral fillers to materials such as polypropylene, has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished part - properties which can be further influence by loading level.  

But if you're new to the world of mineral fillers, or considering using them in an application for the first time, you might be asking yourself, how do I determine the proper loading level for my application? To shed some light on the subject our friends at Heritage Plastics have contributed the following guest post discussing methods to help determine the optimum loading level for thermoforming applications:

Polypropylene Outperforms Paper in Environmental Impacts Study

Posted by Natalie K. MacVarish on March 31, 2017

In a previous blog post, we discussed five key reasons why calcium carbonate filled polypropylene sheet is great for thermoforming applications. Among those reasons, was the sustainability benefits associated with using a filled PP product compared to a resin-only formulation. But evaluating the sustainability of a particular material is not complete until it is compared to alternatives available in the market. To provide a full-circle sustainability evaluation, a study conducted in 2016 by Franklin Associates for Heritage Plastics evaluates the environmental impact of a thermoformed CaCO3 filled PP cup compared to a popular alternative – the polycoated paper cup.

Deciding Between Calcium Carbonate and Talc Filled Polypropylene Sheet

Posted by Blake Kingeter on December 7, 2016

Working with polypropylene sheet for the first time often presents new challenges for thermoformers including shrinkage, low rigidity, and low stiffness. The addition talc or calcium carbonate mineral fillers can help remedy these problems while contributing added benefits compared to resin-only formulations.  But while talc and calcium carbonate both offer benefits, we often find our customers asking, “what’s the difference?”
