Abstract

A film is provided, including 10 to 20 weight percent of a thermoplastic elastomer, preferably a chlorinated polyethylene, 10 to 20 weight percent of a thermoplastic that is a chlorine-based plastic, less than 15 weight percent of a modifier that imparts predetermined mechanical properties to the film, and 20 weight percent or less of a nondiffusing plasticizer, less than 40 wt % of a filler and 20 wt % or less of a flame-inhibiting material.

Claims (9)

1. A film comprising:

10 to 20 weight percent of a chlorinated thermoplastic elastomer with respect to a total weight of the film, wherein the chlorinated thermoplastic elastomer is a chlorinated polyethylene;

10 to 20 weight percent of a thermoplastic with respect to the total weight of the film, wherein the thermoplastic is a chlorine-based plastic;

less than 15 weight percent of a modifier with respect to the total weight of the film, wherein the modifier is a resin that imparts predetermined mechanical properties to the film;

20 weight percent or less of a nondiffusing plasticizer with respect to the total weight of the film;

less than 40 weight percent of a filler with respect to the total weight of the film; and

20 weight percent or less of a flame-inhibiting material with respect to the total weight of the film, wherein the flame-inhibiting material comprises 1-10 weight percent antimony trioxide with respect to the total weight of the film and 5-15 weight percent decabromodiphenylethane with respect to the total weight of the film.

2. The film according to claim 1 , wherein the film comprises 5 to 20 weight percent of the plasticizer with respect to the total weight of the film.
