In comparison to powder and granular pigments, liquid has a superior dispersion rate to ensure a quick and uniform mix within the concrete, far less streaking, and less waiting. Custom colors can be achieved and we can match other manufacturer's color charts (pricing will vary). 64 Standard Colors - 1% Loading Column - $23.95 / 1 yard of concrete (3500 psi) 2% Loading Column - $45.31 / 1 yard of concrete (3500 psi) 3% Loading Column - $67.31 / 1 yard of concrete (3500 psi) 4% Loading Column - $87.92 / 1 yard of concrete (3500 psi) Please Note: We sell many colors of POWDER to match liquid colors as well!

Liquid Vs Pellet Color Is a Critical Feature in Consumer Packaging That Enables Brands to Create Differentiation and Recognizable Identity on Shelf
Plastic Colorant Options 101: Liquid vs Pellet Color is a critical feature in consumer packaging that enables brands to create differentiation and recognizable identity on shelf. Major brands and their packaging supply partners are rethinking their colorant strategy. How do you find the right value-added color supplier? Most color suppliers have a fixed portfolio of either liquid colorants or traditional pellet colorants, thereby leaving processors confused about choosing the best colorant technology to accomplish their goals. Both technologies have advantages and disadvantages. Below, is a quick overview of both liquid and traditional pellet options followed by two case studies in which color- processing challenges were overcome using a new pelletized color technology solution. Liquid vs. Pellet: Liquid Colorant for manufacturing plastic products: Ad vantages: Challenges: - Effective at extremely low use rates - Specialized pumps are required - Suited for tints - Several pigment and additive limitations. - Good color distribution - Production interruptions caused by container - Less history than pellet concentrates changeover - Coloring cost can be lower than - Screw slippage at high use rates conventional pellet - Limited application with engineered polymers - Not suitable for extrusion blow molding of HDPE bottles - Increased housekeeping issues related to spill cleanup and storage of dedicated hoses - Limited shelf life due to product separation that ends up increasing costs and wasted color - Issues with sustainability due to wasted/residual -

Mazzarella to conduct an independent investigation of how best to support the plastics industry. The authors gratefully acknowledge the "hands-on" support of the Leominster Office of Planning and Development, particularly Joseph Viola, Plastics Technology Coordinator, Mary Albertson, Director and Trevor M. Beauregard, Economic Development Coordinator. We especially want to thank Joe for the unstinting assistance he provided through the life of this project. As we began our work, we reached out to the North Central Chamber of Commerce and its Plastics Council. Todd Simkus and Dan Curley of the Chamber's staff provided critical assistance in allowing us to involve plastics companies directly in our research. Dan's assistance, working with Joe Viola, was essential in organizing the forums where we discussed the findings and recommendations that emerged from our research. We also want to thank Mark LaVoie for inviting us to meet with the Plastics Council when our effort was getting underway. Staff of the Donahue Institute, Carolyn Mailler, Rebecca Loveland, Ruth Malkin, James Palma, Jennifer Woods, Carlos Gonzales and Irma Bushati, stepped in at critical times with editorial assistance and research. -

Introducing Plastic Product Design Into the Machine Design Curriculum
Session 2566 Introducing Plastic Product Design into the Machine Design Curriculum Reginald G. Mitchiner, Ph.D., and John T. Tester Mechanical Engineering / Industrial and Systems Engineering Virginia Polytechnic Institute and State University Blacksburg, VA 24060 Abstract We present our paradigm of plastic product design as a necessary part of the mechanical engineering design curriculum and how these concepts have been a historical part of the mechanical engineering educational agenda, though in other venues. We discuss the practical and accreditation problems associated with incorporating the "new" design features in an existing machine design course. A separate design course, dedicated to plastic product design, is also outlined. This last alternative is likely the best bridge from a machine design curriculum without plastics concepts to one with metallic/nonmetallic product design. 1 Introduction Plastic products† are a dominant part of the manufacturing world. It is very likely that you the reader could, at this moment, reach out and touch a plastic product from where you sit. Yet, mechanical design curricula at universities, as a general rule, do not have plastic product design integral in their construction. The mechanical design curriculum has embedded within it the classical theory associated with metallic products; usually these products are assumed to be manufactured via metal-removal processes, if their manufacture is assumed in any manner at all. As practicing mechanical design engineers, we (the authors) have frequently been required to design products with a plastic component as part of their basic structure. One of the authors' primary functions for several years was to design solely plastic products as part of electronic product packaging.
