Abstract: A thermoplastic composition includes: a transparent thermoplastic resin; from about 0.1 wt % to about 2 wt % of a mold release agent including pentaerythritol tetrastearate (PETS); and from 0.01 wt % to about 5 wt % of a stabilizer component. The PETS is derived from an aliphatic carboxylic acid having less than 50 wt % content of C18 or longer alkane chains. The thermoplastic composition has improved transparency properties as compared to comparative compositions including PETS derived from an animal source.

Abstract: A thermoplastic composition includes: (a) a thermoplastic polymer component including a crystalline or semi-crystalline polymer: (b) carbon fiber: (c) from about 0.01 wt % to about 10 wt % of at least one nucleating agent including a non-electrically conducting filler, an organic nucleation agent, or a combination thereof; and (d) from 0 wt % to 30 wt % of an amorphous polymer. The carbon fiber has a nominal fiber diameter of from about 3 micron (μm) to about 13 μm. The composition has a surface resistivity that is at least 50% lower than that of a substantially identical reference composition that does not include the at least one nucleating agent. The combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the thermoplastic composition.
