BRP Manufacturing Company - Lima OH Alliance for Sustainable Energy, LLC - Golden CO
International Classification:
C08C 19/25 C08K 5/3412
US Classification:
525342, 5253261, 525387, 136251, 136259, 524 86
Abstract:
Compositions suitable for use as encapsulants are described. The inventive compositions include a high molecular weight polymeric material, a curing agent, an inorganic compound, and a coupling agent. Optional elements include adhesion promoting agents, colorants, antioxidants, and UV absorbers. The compositions have desirable diffusivity properties, making them suitable for use in devices in which a substantial blocking of moisture ingress is desired, such as photovoltaic (PV) modules.

Rubber Formulation With Enhanced Flex Fatigued Resistance
- Karben, DE Thomas George Burrowes - North Canton OH, US Prem Thapa - Fairlawn OH, US
Assignee:
ContiTech Techno-Chemie GmbH - Karben
International Classification:
C08L 23/16
Abstract:
A rubber composition is provided which exhibits a high level of flex fatigue resistance, ozone resistance, building tack, bondability to diene based rubbers, and low temperature resistance. The rubber composition contains EPDM rubber, natural rubber, high cis-1,4-polybutadiene rubber, and from 5 phr to 30 phr of a butyl ionomer.
