Many people assume that if a masterbatch has the same color, it can be used across different plastic products.<\/p>\n
In plastic material development, however, the same color does not always mean the same specification, and the same specification does not always mean suitability for every application.<\/strong><\/p>\n What truly affects product performance is not only color, but also application, processing conditions, contact environment, regulatory requirements, and end-use expectations.<\/p>\n A customer originally used a yellow masterbatch for trash bag production.<\/p>\n For trash bags, the key requirements usually include basic appearance, stable processing, cost control, and suitability for the original application.<\/p>\n Later, the same yellow masterbatch was used for disposable raincoats without re-evaluating the material specification.<\/p>\n However, raincoats may come into contact with clothing and the human body. They may also be used under wet conditions, friction, and temperature changes.<\/p>\n As a result, color transfer occurred and stained clothing at the customer end.<\/p>\n The issue was not necessarily poor masterbatch quality. The real problem was that the material was used in an application it was not originally designed for.<\/strong><\/p>\n Another customer originally used a green masterbatch for plastic strapping.<\/p>\n Plastic strapping usually focuses on strength, toughness, processing stability, and cost efficiency.<\/p>\n Later, the same green masterbatch was applied to shopping bags that could come into contact with clothing or other goods.<\/p>\n Under long-term contact, stacking, friction, or temperature changes, color migration occurred and caused staining issues.<\/p>\n This case shows that even if the color looks the same, the material may not be suitable for a different product application.<\/strong><\/p>\n Material engineers do not evaluate color alone. They also consider the actual application conditions of the product.<\/p>\n These conditions can directly affect pigment selection, additive design, testing requirements, and overall formulation.<\/p>\n Color migration refers to the transfer of color from one material to another due to friction, heat, moisture, pressure, or long-term contact.<\/p>\n In plastic products, common risks include:<\/p>\n Color migration may not appear immediately after production. It can occur during transportation, storage, or actual use.<\/p>\n Many people think that once a product passes final inspection, it is safe and reliable.<\/p>\n In reality, quality is built throughout the entire process, not only checked at the end.<\/p>\n At KCI Master, our quality control process may include:<\/p>\n The purpose is to reduce potential risks before products are delivered, instead of reacting only after a problem occurs at the customer end.<\/p>\n At KCI Master, we do more than ask what color the customer needs.<\/p>\n Before formulation development, we also evaluate:<\/p>\n These factors directly influence formulation design.<\/p>\n A good material is not always suitable for every application. The right material for the right application is what truly matters.<\/strong><\/p>\n Not always. Different products may have different application environments, contact conditions, and regulatory requirements. Material suitability should be re-evaluated before use.<\/p>\n Disposable raincoats may contact clothing and the human body under wet and friction conditions, which can increase the risk of color migration.<\/p>\n Plastic strapping focuses mainly on strength and cost, while shopping bags may contact clothing or consumer goods. Without proper evaluation, color transfer may occur.<\/p>\n Color migration is the transfer of color from one material to another due to friction, heat, moisture, pressure, or material contact.<\/p>\n Risks can be reduced by confirming product application, resin type, processing method, contact conditions, regulatory requirements, and quality control procedures during the development stage.<\/p>\n To learn more about masterbatch selection, color control, and plastic product quality, we also recommend:<\/p>\n In plastic product development, color is only one part of material selection.<\/p>\n What truly determines product stability and application suitability is whether the material matches the product\u2019s real use conditions.<\/p>\n The same color does not always mean the same specification. When the application changes, the material should be re-evaluated.<\/p>\n Choosing the right material is the foundation of safe, stable, and reliable plastic products.<\/strong><\/p>\n If you are developing a new plastic product or looking for a masterbatch solution for a specific application, KCI Master can help you evaluate material requirements and select the right solution for your product.<\/p>\n","protected":false},"excerpt":{"rendered":" Why the Same Color Masterbatch Cannot Be Used for Every Product Understanding Material Selection Through Two Real-World Cases Many people assume that if a masterbatch has [\u2026]<\/span><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[58],"tags":[],"class_list":["post-3755","post","type-post","status-publish","format-standard","hentry","category-masterbatch-knowledge"],"_links":{"self":[{"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/posts\/3755","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/comments?post=3755"}],"version-history":[{"count":1,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/posts\/3755\/revisions"}],"predecessor-version":[{"id":3756,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/posts\/3755\/revisions\/3756"}],"wp:attachment":[{"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/media?parent=3755"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/categories?post=3755"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/kcimaster.com\/en\/wp-json\/wp\/v2\/tags?post=3755"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
