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.
Claims25
A camera module comprising a molded part, wherein the molded part comprises a polymer composition comprising:
- at least one liquid crystalline polymer;
- an inorganic particulate material comprising a silicate and 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
- olefin copolymer, wherein the polymer composition exhibits a tensile elongation at break of about 3.5% or more as determined in accordance with ISO Test No. 527:2012 at 23° C. and 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.
