Product Announcement from Celanese Corporation
Vectra® liquid crystal polymers (LCP) are highly crystalline, thermotropic (melt-orienting) thermoplastics that can deliver exceptionally precise and stable dimensions, high temperature performance and chemical resistance in very thin-walled applications.
Ticona has numerous patented LCP polymers that provide a wide range of price/performance options for many industries. Standard injection moldable grades with glass fibers and/or mineral reinforcements are available, along with specialty grades for applications requiring platability, improved lubricity, static dissipation and a whole host of other specific performance requirements.
Vectra LCP provides high stiffness in thin wall sections and a low coefficient of thermal expansion. It can withstand surface mount soldering temperatures, including those needed with lead-free solder. These properties have led to the use of Vectra LCP in many electronic applications such as:
- Chip carriers
Many grades have outperformed ceramics, thermosets and other high temperature plastics.
Vectra LCP has replaced stainless steel in medical applications. Several grades of Vectra LCP are compliant with USP Class VI guidelines and ISO 10993-1. They are resistant to gamma radiation, steam autoclaving and most chemical sterilization methods. Vectra LCPs are specified in numerous medical applications such as:
- Surgical instruments
- Dental tools
- Sterilizable trays and equipment
- Drug delivery systems and diagnostics.
