Toughness of Plastic Materials: Notched Izod Impact Test
Impact 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
Izod Impact - an overview
To determine material resistance, notch-A Izod impact strength tests were conducted in accordance with ASTM D256. Several impact specimens were sintered using a laser power of 50 W, then subsequently filed and sanded to the correct testing parameters, if necessary.
Izod impact strength test - Wikipedia
The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm
Izod Impact Strength Testing of Plastics
Izod impact tests are commonly run at low temperatures - down to -40°F (-40°C) or occasionally lower - to help gauge the impact resistance of plastics used in cold environments. The impact resistance of a specific commercial grade of polymer is a function of the base resin plus the presence of any impact modifiers (such as elastomers) and

Understanding your Data Sheet: Notched Izod Impact Strength
The Notched Izod Impact test is a single point test that measures a materials resistance to impact from a swinging pendulum. Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. The test specimen used in the Notched Izod Impact test are notched to prevent deformation of
Izod Impact (Notched) ASTM D256, ISO 180
Izod Impact Testing (Notched Izod) ASTM D256, ISO 180 is a common test to understand notch sensitivity in plastics. Scope: Notched Izod Impact is a single point test that measures a materials resistance to impact from a swinging pendulum. Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until
Know Your Materials: PC and PC-ABS - TriMech
PC-ABS. PC-ABS is a high-impact, low-volume engineering thermoplastic that creates stronger parts that mimic the material properties of the final product. PC-ABS combines the strength and heat resistance of PC and the flexibility of ABS. This blend is 5-60% stronger than standard ABS. It is currently only available in black.
POLYCARBONATE/ABS ALLOY (PC/ABS)
PC/ABS alloys process with the ease of ABS (RTP 600 Series) materials yet have a toughness similar to polycarbonate (RTP 300 Series) materials. The high heat distortion of the alloy is an improvement over ABS, while the low temperature impact resistance gives it an advantage over polycarbonate.

increasing PC content. In general, impact strength increases with increasing PC content. However, sudden drop in the impact strength value occurred when small amount of PC (20 wt%) was added to the blends. The creep resistance of neat PC exhibited the highest value while neat ABS has the lowest value.
