Abstract
A polymer composition that is capable of exhibiting a unique combination of ductility (e.g., tensile elongation at break), impact strength (e.g., Charpy notched impact strength), and dimensional stability is provided. For example, the polymer composition may contain a liquid crystalline polymer in combination with an epoxy-functionalized olefin copolymer and an inorganic particulate material.
Claims26
A polymer composition comprising:
- 100 parts by weight of at least one liquid crystalline polymer;
- from about 50 to about 90 parts by weight of an inorganic particulate material having a hardness value of about 2.5 or more based on the Mohs hardness scale and a median particle size of from about 0.1 to about 35 micrometers;
- and
- from about 1 to about 15 parts by weight of an epoxy-functionalized olefin copolymer.
A molded part for a camera module, wherein the molded part comprises a polymer composition that includes a liquid crystalline polymer, the composition exhibiting a tensile elongation at break of about 3.5% or more as determined in accordance with ISO Test No. 527:2012 at 23° C., a Charpy notched impact strength of about 6 kJ/m2 or more as determined in accordance with ISO Test No. 179-1:2010 at 23° C., and a dimensional stability of about 6 or less as determined in accordance with ISO 294-4:2001 using a Type D2 specimen.
