Advanced materials developed to meet safety requirements
Published: 23 August 2013 - Rachael Morling
DuPont Performance Polymers has expanded its product portfolio to meet the demanding requirements of the electrical/electronics, food processing, and healthcare industries.
Among the latest advanced material solutions for the electrical/electronics market are non-halogenated nylon 66 grade; while for the food and healthcare industries, recently commercialized grades provide targeted performance and regulatory compliance to support the development of innovative and cost-effective medical devices and food-contact products.
DuPont is also directly engaged in developing resins which allow replacing thermosets which are non-recyclable and developing bio-based materials which can lower CO2 emissions and reduce dependence on fossil fuels. New product offerings must comply with numerous regulatory standards including the Waste, Electrical and Electronic Equipment (WEEE) directive, Restriction of Hazardous Substances (RoHS) Directive, and the REACH regulation on chemicals and their safe use.
The company also now supplies dedicated food-contact compliant resins (FG) which comply with relevant EU and FDA food contact standards for use in a wide range of food-contact applications including closures, dispensing valves, meat casings, small appliance and food processing components, valves, stock shapes for machined components, food service trays, and utensils. These materials are available globally and are consistent with the food industry’s increasing need for quality assurance and consumer safety.
DuPont FG grades also provide a sustainable option by offering manufacturers the ability to replace metal, thus producing lighter, lower cost, and corrosion resistant components often with superior performance. This potential is clearly seen in the food processing industry where a food contact-approved, metal-detectable grade of DuPont Delrin acetal has found increasing use. Specifically, Delrin FG400MTD acetal resin is made with a metal filler so it can be detected by most metal-sensing equipment used in the food processing industry. This food-contact
-compliant resin shares the established attributes of Delrin acetal including low wear and friction and a combination of mechanical properties that have led to a wide range of applications.
The company will highlight the latest developments in product innovation and application development for the E/E, healthcare, and food/material handling segments at the K 2013 exhibition.
