Liquid crystal polymers possess the characteristics listed below:
- Extraordinary chemical resistance
- Outstanding strength at high/low temperatures
- Weatherability
- Excellent dielectric strength
- Dimensional stability
- Flame retardance
- Superb moldability in thin sections
- Vibration damping
- Stiffness
- Minimal moisture absorption
- Low coefficient of thermal expansion
- Biocompatibility
- Ability to withstand various sterilization methods
Properties can be customized by copolymerization with other monomers or through the addition of fillers such as glass fillers, carbon fiber, minerals, graphite flake, carbon black. This enables liquid crystal polymers to meet specific customer requirements.
Master Bond formulates adhesive bonding compounds that adhere liquid crystal polymers to liquid crystal polymers and to other surfaces.
Considerations for Bonding Liquid Crystal Polymers
Select Master Bond systems suitable for bonding LCP include EP30LTE-LO, UV16, and LED405Med. Two-component low viscosity EP30-2 is curable at room temperature. It exhibits superior optical clarity, stupendous tensile strength, and impressive dimensional stability. Master Bond EP30LTE-LO is noted for having a low coefficient of thermal expansion. This thermally conductive system is highly electrically insulative. It is 100% reactive and has a low linear shrinkage. Single component, low viscosity, UV curable product UV16 will cross link rapidly upon exposure to UV light. It passes the NASA low outgassing requirements. ISO 10993-5 non-cytotoxicity tested LED405Med is a nanosilica filled LED curable product with excellent abrasion resistance.
