Materials with high temperature resistance and anti-aging properties are considered to be the technologies with the greatest development potential.

Materials with high temperature resistance and anti-aging properties are considered to be the technologies with the greatest development potential, and nylon has become the preferred material of this kind in the automotive industry. In automotive engine compartments, braking devices, and clutch components, nylon is being used to replace metals and thermosetting materials to further enhance the performance of automobiles in all aspects. 

EMS-GRIVORY: The heat resistance of the material is "positively proportional" to the temperature 

It is understood that the engine intake pressure of modern automobiles reaches 3.3 bar, and the maximum temperature can reach between 210°C and 230°C. EMS-GRIVORY, a leading manufacturer of high-performance polymers, has provided two types of high-temperature-resistant nylon materials for the above temperature and pressure ranges: the co-mingled alloy of highly heat-stable nylon 66/6, Grilon TSG-W, and Grilon TSG-W2. 

With the upcoming implementation of the Euro 6 standard, a peak operating temperature of 250°C will become a reality in the future, and this temperature is very close to the melting point of ordinary aliphatic polyamides. Both PA66 and PA6 materials will reach the limit of their performance. 

To this end, EMS-GRIVORY has developed a new series of polyamides, Griovry HT2VS-HH, with ultra-high heat resistance and stability. And the company's research results have proven that only the materials of this series are fully proven to meet the increasingly growing temperature requirements. 

The product design of the Griovry HT2VS-HH series is based on the ability to maintain the stability of strength for a long time at continuously rising temperatures, especially showing its unique performance in the high-temperature range of 180°C to 250°C. 

Among them, the most remarkable feature is that the heat aging resistance of the material increases with the increase of temperature. When Grivory HT2VS-HH is used between 230°C and 250°C, it can better retain its performance. For example, in a 250°C high-temperature environment test for 3000 hours, the breaking stress of the material remains basically unchanged. 

Radic: Launches a number of new high-temperature-resistant nylon products 

Following the development trends of engineering plastics towards greater lightweighting, metal substitution, and high temperature resistance, Radic Engineering Plastics Group, another excellent global supplier of high-temperature-resistant nylon, has also launched its new high-temperature-resistant nylon product series, RADILION Xtreme: RADISTRONG PA6 and PA6.6 long glass fiber-reinforced nylon as substitutes for metal materials, as well as the RADILION DTPA6.12 and RADILION DPA6.10 long glass fiber-reinforced polyamide series materials. 

Erico Spini, Director of Market and Application Development of the Engineering Plastics Business of the Radic Group, pointed out in his report "Applications of Special Nylons in the Automotive, Electronics/Electrical Industries" at CHINAPLAS 2014 that, under the trends of lightweighting, intensification, and ecologicalization in the automotive industry, many new materials and technologies have emerged. The continuous expansion of "automotive plasticization" has also led to an increase in the application of plastics in the automotive industry. Nylon and modified nylon products with high temperature resistance, oil resistance, chemical corrosion resistance, and high tensile strength, such as highly reinforced nylon, halogen-free flame-retardant nylon, wear-resistant nylon materials, high-temperature-resistant nylon, nylon alloys, and conductive nylon materials, can all be applied to different parts of automobiles, such as manufacturing engine hoods, rocker covers, cooling and heating devices, and fuel tanks. 

Erico Spini said that in the past few years, Radic has expanded its product range, increased investment in research and development and technical support for customers in the Asian region, and expanded its production capacity. The Chinese factory is also gradually developing and growing, and has started to provide efficient and high-quality pre-sales and after-sales services as well as flexible and stable logistics services for domestic and foreign customers. While consolidating its position in the electronics and electrical industry, it has also vigorously developed the automotive industry market and has currently obtained the certification and approval of General Motors, Ford, Volkswagen, Audi, Fiat-Chrysler, and other OEMs. 

Invista: Combining heat aging resistance with excellent processing performance 

In order to meet the growing demand for heat aging resistance in automotive engine applications, Invista Engineering Plastics has achieved further evolution of the TORZEN Marathon technology. 

This technology of Invista is currently under patent application and can provide nylon 66 engineering polymers for product molding manufacturers and automotive OEMs. This polymer has long-term heat aging resistance, while also having good strength, more excellent processing performance, and excellent hydrolysis resistance. 

"For applications that are continuously exposed to extremely high temperatures, the TORZEN Marathon technology is an ideal solution," said Romeo De Castro, Global Product Marketing Manager of Invista Engineering Plastics. "For the automotive and electronics and electrical markets, the first-class heat resistance and low melt viscosity of our technology bring a win-win situation for our customers." 

Compared with traditional nylon 66 heat stabilization technology, the TORZEN Marathon modified polymer has improved heat aging resistance, while maintaining the toughness, wear resistance, heat resistance, and chemical corrosion resistance of nylon 66. Tests conducted by a certified third-party laboratory have found that the TORZEN Marathon resin still has more than 50% tensile performance after continuous use at a temperature of 190°C for up to 3000 hours. The resin can also withstand a peak temperature of up to 230°C for 1000 hours. 

In addition to its long-lasting heat aging resistance, the TORZEN Marathon resin also has processing advantages compared with traditional nylon 66. These advantages include low melt viscosity and shorter molding cycles, while maintaining a shrinkage rate and hydrolysis resistance similar to those of traditional heat-resistant grade nylon 66. With these product characteristics, product molding manufacturers can achieve further product integration design, which helps to reduce costs and reduce the weight of automobiles. 

The TORZEN Marathon technology of Invista has also enhanced the performance of its flame-retardant product specifications, including better retention of mechanical properties after heat aging and low melt viscosity (compared with traditional nylon 66), while also maintaining the V-0 flame-retardant property (with a thickness of 0.4 mm - 3.0 mm). The TORZEN Marathon technology is the latest research achievement of Invista and can help molding manufacturers of global automotive and electronics and electrical applications develop new solutions. De Castro added: "With this new technology, our technical team and application research and development engineers actively cooperate with customers to help them create new breakthrough technologies, thus promoting business development. The increasingly flexible component design brings many benefits to the electronics and electrical and automotive markets. For example, it helps original equipment manufacturers meet the upcoming CAFE automotive energy consumption standards."
