Unlike the latter class 92, the class 82 like its sister classes are endowed with multi-layered tempered glass that is of a higher degree of impact resistance.

As a method for protecting pipelines, wood lagging offers high-impact resistance at a considerably reduced cost compared to other types of pipeline protection, such as concrete coating.
43.
The resulting impact resistance results in LRPu being used in soft laptop sleeves and other lightweight cases for portable electronic equipment, as an alternative to the softer neoprene.
44.
Another 25 % is used as an additive to improve the toughness ( impact resistance ) of plastics such as polystyrene and acrylonitrile butadiene styrene ( ABS ).
45.
It is used in blends with polyvinyl chloride ( PVC ) because the soft, rubbery chlorinated polyethylene is embedded in the PVC matrix, thereby increasing the impact resistance.
46.
It has good impact resistance and a Young's modulus in the range of 1700 MPa ( see suppliers website ) allowing for self standing items and pressure piping systems.
47.
Low-cost pellets are often considered to have such negative characteristics as residual plastic from the moulding process ( flash ); lower impact resistance and some deviation from perfect spherical shape.
48.
While these composite materials can be lightweight and strong, they have much lower impact resistance than traditional materials and consequently are prone to damage or failure if crashed or mishandled.
49.
Tempered hardboard is hardboard that has been coated with a thin film of linseed oil and then baked; this gives it more water resistance, impact resistance, hardness, rigidity and tensile strength.
50.
Where the wheel openings of any car are a major source of wind resistance, the design was rather primarily an engineering design to increase the strength of the car for impact resistance.
