INFORMATION & IDEAS
A quick guide to elastomer properties and application development assistance.
You can greatly enhance performance and dependability by selecting and specifying parts made with DuPont™ Viton® fluoroelasatomer, a superior FKM material. Bear in mind that not all FKMs are equivalent.
DuPont offers a range of materials designed to resist high temperatures and aggressive fuels in automotive fuel hoses.
Ford, Fiat and Toyota walked away with innovation awards at the 2011 Society of Plastics Engineers “Most Innovative Use of Plastics Awards” event for components that use two renewably sourced DuPont materials — DuPont™ Zytel® RS nylon and DuPont™ Sorona® EP polymer — and one component using DuPont™ Hytrel® TPC-ET.
Automotive seals, gaskets and o-rings made with Viton®have demonstrated resistance to harsh fuels and lubricants at high temperatures andmaintain sealing at low temperatures to help OEM’s increase durability and meet lower emissions requirements.
DuPont has a portfolio of chemical resistant elastomers and thermoplastics to match a broad spectrum of challenges – from aggressive automotive fuels to custom industrial equipment.
DuPont is working with our auto industry collaborators to help them develop the next generation of sustainable mobility solutions. Together, we’re helping reduce dependence on fossil fuels and lower greenhouse gas emissions to help manage the environmental impact associated with the world’s increasing demand for automotive mobility.
With global biofuel use expected to double by 2015, DuPont has developed a new generation of heat-, pressure- and chemical-resistant elastomers for fuel system components that can withstand aggressive fuel environments.
Brief summary of the US EPA's (Environmental Protection Agency) "Level's of Protection (LOP)" as applicable to those individuals involved in handling hazardous materials. LOP's are based on the type of respiratory protection required to ensure the safety of the user under the specified conditions of use.
What are the differences between “inherent” and “treated” flame resistant fabrics? Learn how each fabric reacts when exposed to heat, and when flame-resistant properties can be removed.
Fuel Line Made of Renewably Sourced DuPont™ Zytel® Nylon Provides Long-Term Resistance to Biodiesel
Toyota Camry Hybrid with fuel pump sender seal of DuPont™ Viton® fluoroelastomers meets PZEV-Phase III fuel permeation limits
DuPont offers a range of tested heat resistant elastomers for applications from automotive engines to oil and gas production equipment.
DuPont collaborates with customers worldwide to develop innovative metal replacement applications to make cars, planes and other equipment more fuel- and cost-efficient.
Kalrez® parts last longer and seal more effectively than other elastomers due to their exceptional heat resistance. Even after long-term exposure up to 327°C, they retain elasticity and recovery properties better than other high temperature elastomers.
DuPont has been working on PA12 alternatives and has established global development and supply teams to work with customers to quickly qualify alternative materials for use in many automotive and industrial components.
Recent testing of DuPont™ Vamac® ultra ethylene acrylic elastomers (AEM) and new grades of DuPont™ Zytel® nylon resins and semi aromatic DuPont™ Zytel® HTN in aggressive AdBlue* aqueous urea solution has demonstrated the effectiveness of these products for selective catalytic reduction (SCR) systems used to reduce NOx emissions from diesel engines.
DuPont supports efforts/initiatives to improve sustainability in the automotive industry with high performance and renewably-sourced polymers that can help increase fuel efficiency while reducing energy loss, emissions and costs.
The auto industry’s current materials portfolio will need to be augmented to meet new 2025 fuel economy standards, according to a recent WardsAuto and DuPont Automotive survey in July of 2011. Respondents also said materials used in power train vehicle systems will change the most.
Vehicle weight reduction is a major challenge. While plastics are inherently lighter than metals, lightweighting requires more than direct material substitution. DuPont predictive engineering and design teams work with customers, using insight and high-performance DuPont materials to redesign for lower weight, often integrating functions to cut costs at the same time.
DuPont™ Viton® made with APA technology provides improved processing characteristics such as flow, cure and mold release. Additionally, Viton® APA types provide excellent tensile strength, compression set, and chemical resistance.
