Custom plastic designs are getting more and more complicated.With the advances in technology, customers, designers and end-users now want extrusions that match the item they are designing. That has posed a problem for professionals in the extrusion industry. Do extruded plastics accept paint? What is the best way for color to be included in plastic materials? Here are some tips to think about when considering color for your next extrusion project:
- Getting color onto your plastic parts. You may think that paint is the only acceptable method to coloring your parts in a way that will be long lasting. That is not true. There are other ways to give your extruded parts color that will highlight their design.
- Paint can change the durability of your plastic parts. Paint, a chemical compound, when added to plastics can change the durability of your parts. As much as it is important to have parts that meet the color requirements of your customers, adding paint may not be the right choice.
- Mechanical capacity can be changed when paint is added to extruded plastic parts. If you have tested an extruded plastic part without paint and it meets the specifications for the project, don’t assume that the same mechanical strength will be maintained should you paint the parts. Adding paint can create a chemical reaction that will change the composition of the plastic and can either increase or decrease the density of the plastic.
- Heat and paint can react. Remember that if you use paint on extruded plastics there may be an issue in a thermally charged environment. Paint can react and melt in heat. It may not be safe to use.
What is the best solution? There are ways to color match your plastics without compromising on durability, mechanical load or thermal resistance. Connect with Extrudex today to learn more about how our extruded plastic materials can work for you.
