VESTODUR® X7061 WH E10025 an easy-flow heat-stabilized and fast solidifying polybutylene terephthalate injection molding compound which has been developed for laser marking. Products made of X7061 permit an efficient and fast laser marking.

The characteristic properties of PBT remain unchanged:
- high heat deflection temperature
- high rigidity
- very low moisture absorption and high
- dimensional stability
- high hardness and strength
- good friction properties, low abrasion
- low creep, good long term performance
- good electrical properties
- resistance to chemicals and weathering
- good processability
- no tendency to stress cracking

VESTODUR® X7061 is a special compound which makes it suitable for marking by a Nd:YAG laser. The emitted radiation with a wavelength of 1064 nm (near infrared) causes a color change into a deep brown black, regardless of the initial color of the compound.

Besides an intense contrast, especially in cases of bright colors of the compound, the quality of the surface meets high demands.The surface of the products is not deteriorated; the good abrasion and chemical resistances are maintained.
The main advantage of the process is the high degree of versatility. Changes in layout are simply realised by appropriate software of the controlling computer. That permits cost effective, long lasting and well legible marking, even with frequent changes in layout.

Typical applications:
Electrical industry: Switches, relays, housings, connectors, coils, cable identifications.
Electronic industry: Active and passive components as condensers and relays.
Data processing and telecommunication: Parts of housings, key tops of keyboards and phone sets, computers, cellular phones etc.
Other applications: Fraud proof labels and stickers for apparatus or assemblies.
