Toray liquid crystal polyester resin SIVERAS* is a super engineering plastic that was developed on the basis of Toray's advanced technology for polyester resin production.
It offers the following properties that are not found in standard engineering plastics: 1. High strength and high flexibility, 2. High heat resistance, 3. Dimensional stability, 4. Good molding properties, 5. 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 of SIVERAS*
- High strength, high flexibility.
- SIVERAS* offers superior strength and flexibility. 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 ℃ 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 ℃ 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.
- Flame retardant
- SIVERAS* L204G35 conforms to UL94V-0 for thin walled parts with a thickness of 0.38 mm.
