Tensile strength filled grades

Glass-fiber-reinforced (increased stiffness and tensile strength) and mineral filled (reduced shrink and warp) grades also have been developed. 

LCPs maintain a highly-oriented molecular structure in both the molten and solid states. In general, such polymers are known as rodlike polymers, and exhibit extremely strong mechanical properties in the direction of molecular orientation. For example, unfilled grades of Type II LCPs exhibit tensile strength of 200 MPa and flexural modulus of 9 GPa (both values are of 3 mm thickness), which are values that cannot be reached even with glass filled conventional polymers. 

LCPs ease of processing gives them the ability to fill long, narrow molds, which makes them eminently suitable for such high-performance parts as electronic connectors. They may have 138,000 kPas (20,000 psi) or more in tensile strength, with flexural modulus values up to 5 x 10 psi. They are available in grades with heat deflection temperatures (HDT) of about 357°C (675°F) at 1,820 kPas (264 psi). This family of different LCPs resists most chemicals and weathers oxidation and flame, making them excellent replacements for metals, ceramics, and other plastics.
