Impact polypropylene copolymer
WitrynaImpact test signifies toughness, or impact strength, of a material that is the ability of material to absorb energy during plastic deformation. This energy absorption is directly related to the brittleness of the material. Results of impact tests are expressed in terms of either: Amount of energy absorbed (Nm) or.
