Toray SIVERAS™ LCP Resin LX70T45 Liquid Crystal Polymer (LCP)
Categories: Polymer; Thermoplastic; Liquid Crystal Polymer (LCP)

Material Notes: filler reinforced, toughness, low gas, low warpage, LCP-(GF+MD)45.

General Siveras™ Notes: SIVERAS™ liquid crystal polyester resin offers the following properties: High strength and high modulus, High heat resistance, Dimensional stability, Good molding properties, Good vibration absorption properties. A special feature of SIVERAS™ is its superiority to conventional liquid crystal polymers in terms of molding properties (fluidity, stability in retention).

Features:

  • High strength, high modulus. SIVERAS™ offers superior strength and high modulus. Molded products feature a highly oriented in molecular chain, the thinner the molded products. This further improves strength and elastic modulus.
  • Heat resistance: The heat deflection temperature is 250°C or higher. Offering outstanding soldering heat resistance, it can be used stably for electronic parts for SMT.
  • Dimensional stability: No change in dimensions due to moisture absorption. The linear expansion rate in direction of flow is comparable to values for metal.
  • Molding properties: SIVERAS® offers outstanding fusion fluidity for molding of thin walled products. SIVERAS® can be molded at low pressure and offers fast crystallizing speeds to eliminate formation of flash. Can be molded at mold temperatures of 100°C degrees or less, as is true for PBT resins. The stability in retention during molding is on a par with conventional liquid crystal polymers.
  • Vibration absorption: SIVERAS™ offers outstanding vibration absorption regardless of high elastic modulus.
