Now days, polypropylene, polyethylene and other polymer resins are the second most commonly found materials in cars as plastics
The use of polypropylene, polyethylene and other polymer resins as plastics in the construction of automotives has continued to grow over the last decades. Now days they are the second most commonly found materials in cars.
There are four reasons why polypropylene, polyethylene and other polymer resins is used in car manufacturing:
polypropylene, polyethylene and other polymer resins reduce the weight of cars.
To give you a concrete example in numbers: an average modern car weighing 1,500 kg contains about 20% of plastic materials (considering thermoplastics and elastomers). This means 300 kg distributed over 2,000 parts and components of all shapes and sizes.
The primary advantage is that plastics make cars lighter, hence cutting fuel demand and greenhouse gas emissions. For instance, a reduction of 100 kg in the weight of a modern car leads to a reduction in fuel consumption of approximately 0.4 litres per 100 km and in CO2 emissions of around 10 g per km.
Polypropylene, polyethylene and othe polymer resins contribute to the safety cars.
Polymers play a crucial role in car safety. For instance, bumpers made of polycarbonate (PC), polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), polyurethane (PUR), polyamide (PA) compounded with glass fibers, usually weigh 50% less than those made of alternative materials, while absorbing four to five times more energy during impact.
In addition, durable polyester fibre seat belts, airbags made of high-strength polyamides and plastic child restraint seats have all helped to make cars safer for road users.
Polypropylene, polyethylene and other polymer resins help to lower car manufacturing costs
Single mould components have helped to manufacture to decrease vehicle assembly time and quickly introduce design innovations at lower costs. A plastic fuel tank made of high-density polyethylene (PE-HD) is inert to the corrosive environments inside and outside of the tank.
Polypropylene, polyethylene and other polymer resins advance the design of vehicles
Designers and engineers are free nowadays to create innovative design concepts enhancing the functionality of vehicles. Paint protection film (PPF) is a thermoplastic urethane film that is slowly replacing traditional automotive paint on some parts of new cars.
It is 15 times thicker than traditional paint and more resistant to scratches, chips, and UV degradations, retaining a high-gloss shine longer than traditional paint.
Polymers are also contributing to a number of exciting innovations in this field, including key components for electric, hybrid and hydrogen-powered vehicles. New alternative energy vehicles incorporate advances in battery technology using new-generation lithium-polymer batteries that are smaller and run cooler.
They are also used to create fuel cells which power hydrogen cars. As these cars will become more common, the introduction of these technologies will help Europe achieve its 2020 goals of ensuring that 10% of the transport sector must supply its energy needs from renewable sources.
