About Us

It has been a remarkable 83 years. We started as an importer of birch wood flour from Sweden. Today we are a major manufacturer of Plastic Blasting Media, a distributor of a multitude of fillers and extenders, and the largest supplier of Walnut Shell grits and flours in the world. In total, we have more than 200 products in our line, many of which are very unusual.

Our global distributor network of abrasive distributors is unique in our industry. We have distributors covering North and South America, Europe, Australia, New Zealand, and the Pacific Rim.

Headquartered in Milford, CT, USA, our expanded manufacturing facility has increased our ability to grow. All of our business functions are now housed in the same location. This facilitates training, development and manufacturing innovation.

We're Close to Our Customers

Let's talk about personal service. From our earliest days, our company has offered ongoing technical service "FREE" to our customers. Our customers trust us. Their confidence in our products and our problem-solving abilities have greatly contributed to our accelerating growth over the years. w1
