Abstract
There is disclosed a method of producing a molded latex product which does not require a vulcanizing step.
Claims15
A method of manufacturing a latex product without vulcanization, comprising:
- adding from about 0.5% to about 2.0% of a setting agent and from about 0.5% to about 2.0% of an anti-foaming agent to a latex compound to form a latex mixture;
- injecting said mixture into a mold;
- subjecting said mixture to one of cooling and heating, and thereby causing said mixture to be formed while said mixture is in said mold;
- removing a molded article from said mold;
- drying said article;
- and
- washing said article.

A method of manufacturing a latex product without vulcanization, comprising:
- adding from about 0.5% to about 2.0% of a setting agent, about 0.5% to about 1.0% of a water based dispersion pigment, and about 0.5% to about 2.0% of a combination of silicone and emulsifier to a latex compound to form a latex mixture;
- injecting said mixture into a mold;
- heating said mixture for a period of about 10 minutes to about 30 minutes at a temperature ranging from about 70.degree. C. to about 100.degree. C. and thereby causing said mixture to be formed while said mixture is in said mold;
- removing a molded article from said mold;
- drying said article for a period of about 48 hours to about 60 hours at a temperature ranging from about 60.degree. C. to about 75.degree. C.;
- washing said article in an aqueous wash;
- and
- drying said article for a period of about 1 hour to about 3 hours at a temperature ranging from about 55.degree. C. to about 75.degree. C.
