Saint-Gobain Performance Plastics has announced the launch of its Coretech? barrier membrane technology platform, which enables the engineering of versatile and lightweight chemical and biological-protective composites. This technology allows for highly innovative solutions that improve product performance and cost-effectiveness.

Coretech has already been demonstrated in a range of applications:

• Coretech UniGuard used in the ONESuit? line of hazmat suits, which offer maximum protection against the permeation of chemical and biological substances in both liquid and vapour form
• Coretech ShelterGuard, lightweight CBRN fabrics to reduce set-up and tear-down times for protective shelters, military expedition tents and medical treatment units
• Coretech HydroGuard for potable water containment as used in CamelBak? CBR X reservoir units for personal hydration, and
• Coretech EnviroGuard used for chemical or fuel containment bladders or tank liners.

Every Coretech composite is engineered to deliver key performance benefits such as permeation resistance to more than 100 chemicals, including biological and chemical warfare agents. Other benefits include durability and robustness, non-combustibility and flame resistance, low weight, and flexibility. Suitable for use with a wide range of fabrication methods such as welding or stitch and over-tape, Coretech facilitates the development of engineered solutions to a whole range of barrier and containment challenges.

Developed through Saint-Gobain's expertise in fluoropolymer (PTFE) films and fabrics, Coretech represents a range of new customized composite membranes to meet the toughest barrier requirements. These barrier membranes are made by combining different polymers, elastomers and woven and non-woven substrates to achieve unique combinations of properties, which will reliably deliver the required performance levels.

"The potential applications for this new technology are limitless," said Peter Kirk, Market Manager, Saint-Gobain Performance Plastics. "We welcome the opportunity for co-innovation in a broad range of future applications."

Saint-Gobain Performance Plastics (SGPPL) is a subsidiary of Saint-Gobain, one of the top 100 industrial companies in the world and a leading producer of construction products, flat glass, high-performance materials and packaging.
