Automotive plasticization - do you believe it?

With the continuous innovation of technology, the concept of lightweight car has become more and more intense under the current trend of energy saving and emission reduction. In addition to carbon fiber that can effectively reduce weight, cheaper plastics are slowly replacing the previous metal parts. Some family cars are slowly gaining popularity. In the minds of many people, plastic parts tend to be cheaper with cars that are less robust and have a higher proportion of plastics. If you still hold this idea, then you are out! Today's cars have already covered a large number of plastic parts, such as bumpers, wheel covers, license plates, dashboards, and even hoods, all using plastic parts.
“General plastics have a specific gravity of 0.9 to 1.6, and the proportion of glass fiber reinforced composites will not exceed 2.0, while A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. This makes plastic the preferred material for automotive lightweighting. The use of plastic can reduce the weight of parts by about 40%, and the cost can be greatly reduced."
In developed countries, the amount of plastics used in automobiles is an important indicator for measuring the level of automobile design and manufacturing. The amount of plastic used in each vehicle has increased from 100-130kg in the 1990s to 152kg in 2004 and 174kg in 2006. Now The dosage is 230kg. At present, Germany uses the most cars, accounting for more than 15% of the vehicle materials. Experts predict that by 2020, the average plastic consumption of automobiles will probably reach 500kg / vehicle, accounting for more than 1/3 of the vehicle materials. In the future, the technological content of plastics will be higher, and the application will naturally be broader.
However, the use of plastic does not mean to reduce the safety performance of the vehicle. In the energy-absorbing part, most mainstream models still use metal parts. Plastic energy-absorbing parts also require a lot of tests to collect data and confirm the feasibility. So car plasticization is not a rare thing.

PVC,know as polyvinyl chloride is one of the mostly common used materials in plastic field.

PVC profiles also called uPVC profile or PVC-U profile are the based materials for making one 

uPVC window and doors.Through high speed mixer,hot mold extrusion,cutting into customized

 length,then package by plastic bags. Finally could get pieces of uPVC frames,PVC sash and Double Glazing beads.


The most significant properties of Polyvinyl Chloride (PVC) 


Density: PVC is very dense compared to most plastics.
Economics: PVC is readily available and cheap.
Hardness: Rigid PVC is very hard.
Strength: Rigid PVC has extremely good tensile strength.
