Driving innovation in a mobile world
Ever more sophisticated in design, today’s cars feature innovative finishes outside and a wide choice of color inside.
Trends in the automotive industry, however, extend far further than appearance: the demand for higher durability combined with environmentally more compatible technologies is leading to new approaches and advances in product development and application technology.
Strong focus on safety is resulting in developments in digital technology, such as communication between vehicles on the road.
Increasingly stringent fuel economy regulations have boosted demand for lighter weight vehicles and plastics are frequently being used to replace materials such as metal and glass.
Plastics offer high potential inside and outside the car
Besides reducing weight, plastics also help to improve safety, facilitate assembly, cut maintenance and fuel costs, allow new design options and enhance cost versus performance.
Plastics are today used on an ever increasing scale for parts of the car body, including fenders, headlights, doors, windows and many other components. Inside the car, they are used for dashboards, head panels, upholstery and much more. Plastic can also be used to achieve functional effects, such as sound, vibration, thermal and electrical insulation, and surface effects, such as gloss and texture.
The main types of plastic components used in the automotive industry are polypropylene (PP), polyurethane (PUR) and thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), styrenics, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), ABS/PC blends, polyamide (PA) and polybutylene terephthalate (PBT).
Both the exterior and the interior of cars are subjected to extreme conditions of heat and light. The plastics used in the automotive sector therefore need to be exceptionally resistant. .
As a leading industrial supplier SONGWON develops, manufactures and supplies polymer stabilizers for plastic parts manufactures of the automotive sector such as antioxidants, UV absorbers, hindered amine light stabilizers that help prolong the life of plastics used inside and outside vehicles. Stringent regulations, together with ever increasing demand for environmentally compatible products, has led the industry to focus strongly on reducing emissions from automotive interior compounds. Committed to improving the overall sustainability of its products and processes, SONGWON researches into and develops stabilization solutions that generate few or no volatile organic compounds (VOCs).
Besides polymer stabilizers SONGWON also develops thermoplastic polyurethane (TPU) resins for films and cables and also for injection molding of exterior and interior automotive parts, for both esthetic and haptic reasons. With their excellent bonding, flexibility and barrier properties, SONGWON’s TPU resins for films help to meet the demanding requirements of automotive foam-in-place seat applications, while its TPU resins for cables are designed for reliable transmission of electronic signals.
Coatings add appeal and provide protection
Coatings for automotive and transportation applications not only provide color and texture, but also enhance the appearance and prolong the useful life of vehicles and parts.
Today, there is strong demand for products and processes that combine environmental compatibility with high performance.
SONGWON develops, manufactures and supplies additives for the stabilization of coatings and adhesives that increase the durability of coatings and provide underlying substrates with excellent protection while allowing the formulation of waterborne and powder coatings and minimizing generation of VOCs.
Electronics help increase safety and efficiency
Today’s automotive electronic systems have a wide range of functions, including engine management, ignition control, radio, computers, telematics and in-car entertainment systems. Electronics for the automotive sector can be subject to more extreme temperature ranges than those used in other applications. SONGWON develops, manufactures and markets high-end specialty chemicals for the electronics industry.
Lubricants and fuels perform better with the addition of antioxidants
Antioxidants are added to fuels to cut consumption and enhance engine performance. Lubricants also require additives ‒ to reduce viscosity, to prevent oil deposits, foaming and corrosion, to protect oil at high temperatures and to guard against contamination. SONGWON’s antioxidants for motor oils, diesel oils, automatic transmission fluids and gear oils help extend drain intervals, maintain the required viscosity and reduce deposit formation, without compromising the durability of the engine.
