- Aug 31, 2019-

The automotive plastics Market will grow from more than $20 billion today to more than $50 billion by 2024, according to a new Global Market Insights report released Aug. 27.

Key drivers include a surge in passenger vehicle capacity and consumer demand for fuel-efficient, durable and lightweight vehicles;

Rapid industrialisation and urbanisation in China, India and Japan will drive demand for commercial vehicles, suvs, hyundai cars and HMV.

In addition, the improvement of per capita income and living standard promotes consumers' demand for fashionable and beautiful cars, as well as the demand for driving experience.

Automotive plastics are widely used in a variety of automotive bodies and components, including chassis, powertrain, electronic components under the hood, exterior and interior trim, and fuel systems.

Automotive plastics are durable, scratch-resistant and wear-resistant, which can achieve effective design molding and component integration, and achieve lightweight, shock absorption and noise control.

These resins have great potential in the automotive industry

The manufacturing process of automotive plastic parts mainly involves resin raw materials including polyurethane (PU), acrylonitrile butadiene styrene (ABS), polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), polypropylene (PP), thermoplastic elastomer materials TPE and polyamide (PA), etc..

For example, based on its light weight, durability, energy conservation, corrosion resistance, insulation and noise reduction, the application of polyurethane materials in the automotive industry will be greatly increased.

PU automotive plastic demand is expected to grow by more than 10 percent, according to the report.PU foam is commonly used to make headrest, dashboard skin, handrails and various other automotive interior accessories.

In addition, it is worth noting that composite materials with light weight, high strength, corrosion resistance, high temperature resistance, easy synthesis, flexible design are also more and more widely used in the automotive industry, and will become the main application trend in the future.

Among them, resin composite materials include carbon fiber reinforced plastic (CFRP), glass fiber reinforced thermoplastic materials, glass fiber mat reinforced thermoplastic materials (GMT), laminar molding materials (SMC), resin transfer molding materials (RTM) and hand paste FRP products.

Take a look at some innovative applications of automotive materials.

Innovative polyurethane interprets the healthy and quiet beauty of automobiles

As an important automotive interior material, polyurethane can reduce volatile organic compounds (VOC) content and isolate noise.Many innovative polyurethane car interior and exterior decoration applications bring more healthy and quiet driving experience.

Vehicle odor and VOC are the main factors affecting vehicle air quality, and the sources are very complex.Therefore, how to reduce odor and VOC emissions has become one of the major challenges facing vehicle manufacturers.

TPV with better mobility, wear resistance and light stability

Thermoplastic vulcanized rubber TPV can be widely used in automobile interior and exterior decoration, sealing system, cover, engine cabin parts, gasket gasket and other industrial and civil fields that require flexibility and consistency. This kind of products can be completely recycled and conform to the development trend of automobile environmental protection.

DuPont Transportation & Industrial announced that it has teamed up with ExxonMobil Chemical's specialty elastomer division to develop the new sandupin thermoplastic elastomer vulcanized rubber TPV, which can be used in automotive angular die seals.

By replacing traditional organic slip additives with dupont's silicone-based additives, the two companies developed a new generation of sandupin TPV.

The adhesion of the new brand to the ethylene propylene diene monomer (EDPM) rubber matrix is improved, and the friction coefficient (COF) is reduced, so that the new brand has higher skid resistance when opening and closing doors and Windows.

The new shan du ping thermoplastic elastomer vulcanized rubber TPV, can be used for automobile Angle die sealing strip.

The new sandupine TPV B260 series also offers improved flow performance, wear resistance and UV (UV) light stability.

In order to meet customers' demand for improved angular seal, exxonmobil chemical company not only improves sliding performance, but also strengthens the adhesion between sandupin TPV and EDPM rubber.

However, reducing the coefficient of friction to improve sliding performance has a negative effect on adhesion.Exxonmobil has teamed up with dupont to explore the use of its advanced silicon-based additives, which are expected to outperform the organic additives used by exxonmobil.

The dupont development team found that the synergy between low molecular weight silicone polymers and ultra-high molecular weight silicone polymers provided the low friction coefficients that exxonmobil was looking for.Compared with organic additives, silicone technology provides better smoothness and enhances adhesion to EPDM rubber, which is a key factor to achieve secondary molding.

In addition, it also supports higher melt flow to improve processing ease and throughput, has better wear resistance to prevent doors from being broken, and improves uv stability to help prevent cracking and discoloration.

Innovative polyamide foam was born

Asahi Kasei announced the development of the world's first innovative polyamide Foam, a material called the PA Foam that will greatly reduce vehicle noise and weight.

The material consists of foam beads in the shape of C or macaroni, representing different characteristics:

The excellent rigidity of the c-shaped beads gives them great potential for structural applications as well as for insulation, piping, gaskets or other lightweight components in battery boxes for electric vehicles.

The shape of macaroni, on the other hand, represents a high level of sound insulation and has great potential for automotive applications.Especially in engine room, it is helpful to reduce noise and weight.

The material also provides better interior comfort, suitable for roof and hood, or seat and floor construction.

PA foam made from polyamide can be processed by steam molding process on standard polystyrene molding equipment, and the amount of resin used in the production process is significantly reduced to achieve cost reduction.

Polyamides have high heat resistance, chemical resistance and oil resistance.Asahi chemical USES PA foam as a material for the hood, helping to reduce weight and isolate engine noise.

The new PA foam will be shown at the Stuttgart polyurethane foam exhibition in Stuttgart, Germany on September 10 solstice 12

Foam Expo Europe.It is one of the largest and most influential bubble technology trade shows in Europe.
