Polyonics Introduces Laser Markable Label Materials for Harsh Automotive

Polyonics has introduced new black and TrueWhite™ laser markable label materials (LML), tested to the GMW 14573 and GM 6121M performance requirements for automotive under-the-hood as well as plastics (low surface energy) label applications. These unique materials can be easily ablated by a wide variety of low power lasers, provide flexible, high temperature alternatives to polyester and acrylic LML and are more durable than traditional thermal transfer printed label materials.



The new Polyonics LML materials are available in black (XF-670) and TrueWhite (XF-671 and XF-672) versions. They include high temperature polyimide films, durable cross linked polymer coatings, low surface energy (LSE) pressure sensitive adhesives (PSA) and liners for ease of handling and die cutting. The LML materials can be easily ablated by most low power CO2, YAG, fiber diode, UV and Vanadate lasers with the aggressive PSA adhering to a wide variety of surfaces including metals, plastics, ceramics and resins.

High Temperature Alternative to Polyester and Acrylic LML Materials
The Polyonics LML products provide a higher temperature and more flexible alternative to the polyester (PET) and acrylic LML products currently used in automotive LML applications today. Polyimide is the number one choice for label applications involving exposure to high temperatures and harsh chemicals allowing the Polyonics LML products to provide a higher degree of dimensional stability and have greater resistances to harsh chemicals than polyester (PET) and acrylic LML materials. In addition, the Polyonics LML materials do not exhibit the same brittleness associated with acrylic LML materials.

Superior to Thermal Transfer Printed Labels
The weak link in traditional thermal transfer printed labels (TTP) tends to be the ink. This is particularly true in automotive under-the-hood applications due to the high temperatures, harsh chemicals and high levels of abrasion. The Polyonics LML products have been tested to the GMW 14573 and GM 6121M automotive under-the-hood label performance requirements. The test results show the LML materials provide high temperature, chemical and abrasion resistances as well as superior weatherability when compared to thermal transfer label materials

Polyonics at a Glance

Polyonics manufactures high performance polymeric materials for harsh environments. These include printable and laser markable label materials, single and double coated engineered tapes and flexible substrates with highly reflective and printable top coats. Polyonics materials are used by OEMS and specialty die-cut converters worldwide. The ultra-thin polyimide, polyester and aluminum materials are designed expressly for high temperatures and harsh environments plus provide flame retardant and static dissipative performances for electronics, automobile, aerospace and medical components.
