Feature size changes of the plastic component generally do not occur. Post stress relieving is usually required as vapor polishing sets up surface stresses that can cause crazing [citation needed]. Plastics that respond well to vapor polishing are polycarbonate, acrylic, polysulfone, PEI, and ABS.
Operator skill is critical with this method. When done properly, flame plastic polishing produces the clearest finish, especially when polishing acrylic. This method is most applicable to flat external surfaces. Flame polishing is frequently used in acrylic plastic fabrication because of its high speed compared to abrasive methods.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
Headlight restoration or plastic headlight restoration is the act of restoring aged headlight lenses that have become discolored or dull due the original factory UV protective coating degrading primarily due to UV light and other environmental factors such as road debris impact (stones, sand, etc.) rain, and exposure to caustic chemicals.
Stress from fasteners, plastic welding and molding render polycarbonate susceptible to stress corrosion cracking when it comes in contact with certain accelerants such as salt water and plastisol. It can be laminated to make bullet-proof "glass" , although "bullet-resistant" is more accurate for the thinner windows, such as are used in bullet ...
Anti-scratch coatings are often used on plastic products wherever optical clarity, weathering, and chemical resistance are required. Examples include optical discs , displays, injection-molded parts, gauges and other instruments, mirrors, signs, eye safety/protective goggles, and cosmetic packaging.
Plastic coating is a term that is commonly used in technology but is nevertheless ambiguous. It can be understood to mean the coating of plastic (e.g., metallization of plastics [ 1 ] ) or the coating of other materials (e.g., electrical cable ) with plastics.
Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.
