Yes
Yes, plastic can scratch metal surfaces because plastic is typically softer than metal.
NOTHING
its cheaper to make a plastic from scratch !!
Yes it can. It is hard and plastic and can scratch the clear coat and paint. If it gets caught in your wheel it can do more damage..
Yes tpu case do scratch but hard shell and silicone do not
Try: NOVUS PC-20 Plastic Fine Scratch Remover or Quixx Paint Scratch Remover All the best
there is no way to make a balloon from scratch, but you could use a subsitute for a balloon insted. maybe a plastic bag?
Yes, diamonds can scratch other diamonds. Diamonds are the hardest known natural substance, scoring a 10 on the Mohs scale of mineral hardness. Therefore, a diamond can easily scratch another diamond if sufficient force is applied.
To remove a scratch on a plastic car bumper sand it lightly. If the scratch did not come out, fill it with filler. Next clean the area. Block off the parts of the bumper that you do not want to get paint on. Spray primer over the area and then finish with spray paint in the correct color.
This is a big question and a major technical issue for materials scientists and engineers. The short answer is: there are no truly scratch-proof plastics. Plastic is intrinsically soft material, because it is carbon/petroleum-based. Most minerals (rocks, glass, etc) will easily scratch plastic because they are made of metal oxides, which are intrinsically hard materials consisting only of metal-oxygen bonds. When it comes to scratch resistance, a harder material can always scratch a softer material. So no matter what plastic you have, there will always be a harder material out there that can scratch it, such as diamond, alumina, or zirconia. Some plastics are more scratch-resistant than others, however. Examples of scratch-resistant plastics include polycarbonates, CR-39, polyurethanes, and PTFE. Any plastic can be made more scratch-resistant by applying a scratch-resistant coating, which can be composed of any number of highly engineered silicone resins, epoxies, acrylates, etc which can be thermally or UV-cured. There are hundreds of brand names for scratch-resistant coatings that advertise varying levels of abrasion resistance; many use a steel wool test to define just how scratch resistant the cured coating is. Hope this is along the lines of what you wanted to know.
One way to compare the hardness of two materials is to see which of the materials can scratch the other.
Wooden desks with heavy scratch coating will work fine, but will still be scratched if you move a plastic monitor or the like.
