DuPont Launches Hybrid Membrane Technology for Global Industrial Filters Market

DuPont has announced the global availability of its Hybrid Membrane Technology (HMT) fiber in air filtration bag applications for industrial and commercial manufacturing. The product rollout has begun in the U.S. and Europe with availability through DuPont’s laminator network.

“DuPont HMT is a product with a unique offering and significant benefits for manufacturers in every region,” said Thomas G. Powell, vice president and general manager, DuPont Advanced Fiber Systems. “Our customers now have a product that increases cycle time up to nine times over the incumbent polyester felt, with an improvement in energy efficiency. More importantly, these fibers, only available through our Hybrid Membrane Technology, capture up to 10 to 15 times more dust and particulates in the air compared to incumbents, providing a cleaner environment for workers and consumers inside and outside manufacturing facilities.”

Referred to as “dust collection bags” in the industry, these filtration products are used with exit air to capture particles so they are not emitted to the environment, an increasingly important need as more countries enact regulations for cleaner air. The incumbent polyester felt bags are commonly used at any production facility that generates particulates and dust from wood, cement, asphalt, paint, minerals and powders, etc. HMT fiber bags provide air flow with an improved cycle time and better capture of particulates. Based on industry testing standards, initial DuPont data shows that HMT technology provides energy savings by reducing downtime and providing more consistent pressure levels.

DuPont estimates the global air filtration market at more than $1 billion, with the dust collection segment alone at $300 million.

HMT is a DuPont innovation that is based on nanofiber science. It is produced by DuPont in Seoul, Korea, using a proprietary spinning process that produces continuous filaments with diameters between 200 and 600 nanometers. Hybrid Membrane Technology provides better performance versus the incumbent materials across a variety of air and liquid filtration applications where energy efficiency and reduction of particulate contamination and emissions are critical. It adds breathability and protection to bedding products and provides a unique offering for energy storage, where it can improve the safety, durability, power, and energy performance in a variety of capacitor and battery applications.
