Polyimide film is a lightweight, flexible polymer based material that has excellent heat and chemical resistant properties. Polyimide film can withstand temperatures ranging from -269° C to 400° C. In addition to excellent heat resistance properties, polyimide film also has excellent dielectric properties. Typical applications for polyimide film include multi-layer insulation blankets for space, flexible electronics, tapes, and various other high heat applications.http://www.shunxuan-pi.com/polyimide-film/

“I said, ‘Yeah, that might be good, but there’s limited data on whether face masks are actually effective,’” says Benn, a global-health researcher at the University of Southern Denmark in Copenhagen, who for decades has co-led public-health campaigns in the West African country, one of the world’s poorest.http://www.zojemedicalproduct.com/face-mask/

A snow blower works in two stages; like a snow thrower, it has a rotating auger to scoop up snow, but the snow is then fed into an impeller, which is akin to a powerful fan that launches the snow up to 35 feet away, or farther. At the even more powerful end of the Snow Blower spectrum are three-stage blowers that feature accelerators that chew through hard-packed snow and even ice, crushing it and feeding it into a mighty impeller that can launch snow up to 50 feet away.
