The advent of new and advanced technology has revolutionized the space industry, ushering in a new era of innovation and change brought by private space companies.

Parker Chomerics was recently honored by one customer for its engineering accomplishments in the development and application of its EMI shielding and Thermal Interface Materialsfor challenging applications in private aerospace.

Private space flight companies have increased over the last few decades as more and more government-run agencies are now depending on these private companies to provide technology and engineering support for future space missions.

Getting more companies involved in space missions will "lower the cost and lower the risk" of doing business in outer space, said former NASA chief financial officer Jeff DeWit.

Many companies who have extensive resources and those who have been in the aerospace market for decades are now looking to these relative startups for their new, innovative approach to space technology development.

"Our technology portfolio and material science know-how gives Parker Chomerics a unique advantage,” says aerospace & defense market specialist Sierra Eiden. "We' ve been working hand-in-hand with the established aerospace and defense players for decades, and this experience allows us to bring our knowledge and expertise to the private space startups as well."

Parker Chomerics has helped to address the emerging EMI shielding and thermal interface material needs of the private aerospace industry, while simultaneously aligning with large scale manufacturing protocols and design.

In one private aerospace application, the customer chose the one-part Parker Chomerics THERM-A-GAPTM GEL 37 dispensable thermal gel because of its unique combination of both a high thermal conductivity, at 3.7 W/m-K, and 30 g/min flow rate, coupled with its consistent and repeatable dispensing compared to leading products in the market today.

This design for repeatable dispensing helps to "minimize batch-to-batch flow rate variations which increases efficiency and reduces downtime during the manufacturing process," says Parker Chomerics thermal product line manager Callie King. "And it's particularly suited for spaceflight due to its lower specific gravity compared to other thermal interface materials."

THERM-A-GAP GEL 37 also has passed 1,000 hours of gap stability testing and more than 1,000 hours of thermal cycling testing without any material cracking or degradation in thermal conductivity.

Parker Chomerics regularly tests outgassing of its materials to the industry standard test ASTM E595, developed by NASA to screen low outgassing materials for use in space. THERM-A-GAP GEL 37 registers 0.18% TML and 0.07% CVCM, meeting these low outgassing standards.
