Methyl chloride is CH3Cl.  It is a gas that condenses at -24 °C and is not
the compound being discussed.

Chloroform is CHCl3.  It is more toxic than methylene chloride and I don't
know if it would be effective for this applications.

Methyl chloroform is yet another solvent that has been used to fuse
plastics.  It is much more toxic than methylene chloride.  The full name is
1,1,1-trichloroethane.  This may be in some of the plexiglass welding
formulations.  You should hanlde this stuff with care.
