Automotive hoses
Rely on Vistalon™ ethylene propylene diene (EPDM) rubber in automotive coolant, air and heater hoses, as well as AC and brake hose formulations to achieve outstanding performances in various types of hoses including general purpose hose, heat-resistant hose, high-heat-resistant hose and brake hoses.
Key benefits:- High tear strength
- High temperature and long-term aging resistance
- Excellent flexibility
- Easy mixing and processing
Automotive belting
Vistalon ethylene propylene diene (EPDM) rubber is a copolymer specifically engineered for use in industrial power transmission drive belts. Developed for peak performance, specifically in the grinding manufacturing process, Vistalon™ 706 EPM offers good tear strength and flex-crack resistance. It outperforms chloroprene rubber in heat aging resistance and is a lower-cost alternative to hydrogenated nitrile rubber.
Key benefits:- Extended belt lifetime in a high-temperature environment
- High load to sustain startup
- High resistance to pulley clogging
- Quieter running
Battery case
As electric vehicles (EVs) continue to reshape the automotive landscape, manufacturers are seeking materials that balance durability, safety, and cost-efficiency. Impact Copolymer (ICP) polypropylene is emerging as a key solution in this shift—especially in the design of battery casings. ICP offers a unique combination of high impact strength, dimensional stability, and heat resistance, making it ideal for protecting sensitive battery components under demanding conditions. Its ability to withstand thermal cycling, mechanical stress, and chemical exposure ensures long-term reliability, even in harsh environments. Exceed™ AP3AW is an ideal ICP resin designed for high performance automotive and other battery case applications.
Key benefits:- Enhanced product performance
- Good heat and UV resistance
- Cost reduction opportunities
- Distinct ivory appearance
