Abstract
This invention relates to a composition and method of modifying the surface of a polymeric to produce a film or article with a reduced coefficient of friction (COF) and improved release properties. The reduced coefficient of friction improves both the slip and anti-blocking properties of the material as well aiding in processing of the polymeric material. Additionally, the invention improves demolding and release of the polymeric c material from other polymeric surfaces or adhesives as well as metal molding surfaces.
Claims14
A polymeric composition having a reduced coefficient of friction for use in forming a film or capable of being utilized in various molding processes, the composition comprising:
- a) a polymer;
- and
- b) at least one melt-processable ethoxylated compound additive for reducing the coefficient of friction of the composition where the ethoxylated compound is incorporated into the polymer, wherein the at least one additive has the formula:
- CH3CH2(CH2C2)aCH2CH2(OCH2CH2)bOH,
- wherein a is >9 and wherein b is between 10 and 100.
A polymeric composition having improved slip, adhesive release, mold release and/or anti-block properties for use in forming a film or capable of being utilized in various molding processes, the composition comprising:
