Methods For Improving The Resistance Of Fumigant Sorption In A Produce Container And A Related Produce Containers

US Patent:
8101101, Jan 24, 2012
Filed:
Dec 4, 2006
Appl. No.:
11/633202
Inventors:
Jiansheng Tang - Mars PA, US
Jeffory E. Russell - Sewickley PA, US
Christine Hetzer - Monaca PA, US
David A. Cowan - Cranberry Township PA, US
Assignee:
NOVA Chemicals Inc. - Moon Township PA
International Classification:
B32B 37/00
A23B 4/16
B29D 22/00
C08J 9/00
US Classification:
264 454, 264 25, 521 50, 428 357, 426316
Abstract:
Methods for improving the resistance of fumigant sorption in produce containers made from expandable polystyrene particles in a fumigation process, and related produce containers. An embodiment involves pre-expanding the expandable polystyrene particles to form pre-expanded particles; applying a coating comprised of a chemical selected from the group consisting of mineral oil, polyethylene wax, ethylene vinyl alcohol copolymer, and polyethylene glycol to the pre-expanded particles and in amount of 0. 05 to 5. 0 parts per hundred; and forming the container from the pre-expanded particles. A further embodiment involves applying the chemical coating to the expandable particles; pre-expanding the expandable polystyrene particles to form pre-expanded particles; and forming the containers from the pre-expanded particles. Other methods involve increasing the cell size of the expandable particles used to form the produce container.

Dissolving Insecticide In Monomer

US Patent:
6080796, Jun 27, 2000
Filed:
Aug 19, 1998
Appl. No.:
9/136220
Inventors:
Rebecca B. Liebert - Cranberry Township PA
Christine B. Hetzer - Monaca PA
Assignee:
Nova Chemicals Inc. - Monaca PA
International Classification:
C08J 928
US Classification:
521 64
Abstract:
Insecticides, and particularly termiticides, may be dissolved in monomers polymerized to form foamable polymers, such as polystyrene. The resulting monomer and insecticide may then be polymerized in a conventional manner and either impregnated with a blowing agent or expanded using an extrusion process to produce polymeric foam having insecticidal properties. The polymer may also contain a flame retardant. Such polymers and the foam made therefrom may be used in the construction industry, particularly where insect infestation is a concern.

Impregnating Polymer Beads With Insecticide

US Patent:
6033731, Mar 7, 2000
Filed:
Aug 19, 1998
Appl. No.:
9/136243
Inventors:
Rebecca B. Liebert - Cranberry Township PA
Christine B. Hetzer - Monaca PA
Assignee:
Nova Chemicals, Inc. - Monaca PA
International Classification:
B05D 500
B05D 700
US Classification:
427244
Abstract:
Polymeric beads made by a suspension or an emulsion process may be concurrently impregnated with blowing agent, an insecticide and a flame retardant, if required. The resulting bead is then washed and dried and then may be used for making a foam structure such as a sheet. The resulting foam sheet may be used in the construction industry, particularly where there is a concern of insect infestation.
