Veelo Technologies (Cincinnati, Ohio, U.S.) has recently improved the conductivity of its VeeloVEIL, a metallized nonwoven advanced material, which is now available in 3 mOHM/sq, 55 g/m2, with less than 95% electrical uniformity in a 36-inch-wide continuous product form. The lower resistivity is a noticeable departure from Veelo report in CW’s September 2019 plant tour, which states that VeeloVEIL was engineered to deliver 5-10 milliohms of electrical resistivity at an areal weight of 40-50 g/m2. Veelo adds that the new offering has set a new standard in the high-growth aerospace and defense composites protection market.

According to Veelo Technologies, at 3 mOHM/sq, VeeloVEIL offers twice the specific conductivity of expanded copper foil at 195 g/m2, and 7-150 times better performance than other available metallized nonwovens. Additionally, VeeloVEIL is said to provide superior EMI shielding effectiveness, and is reported by Veelo to be one of only a few products to meet the aerospace and defense industry’s most stringent Zone 1A Lightning Strike Protection requirement.

According to Larry Christy, director of Research and Development at Veelo Technologies, VeeloVEIL is a light, highly conductive and electrically uniform material designed to protect composite air vehicles from electromagnetic effects as well as lighting strikes. The expansion of Veelo’s product capacity to a 36-inch continuous form also enables VeeloVEIL to be used in a wider variety of applications.

VeeloVEIL is available with tailored resistivities from 3-40 mOHM/sq and basis weights from 20-55 grams/m2. It is available in dry reinforcement, film adhesive or surfacing film.
