1.Brief introduction
This polypropylene pearl films tensile testing machine is to measure tensile strength and elongation at break of polypropylene pearl films( films of single surface heat and both surfaces heat, films of non-heat).
2.Sample
Mateials of polypropylene pearl films include main material polypropylene resin and a certain amount of pearl materbatch. By the biaxial orientation tensile with method of membrane, so the polypropylene pearl films is made. When measuring its tensile strength and elongation at break, a sample with size 150x15mm±0.1mm should be taken from the whole film and then load tensile force to the sample with a speed of 250mm/min±10mm/min.

1.Applications ans features-torsion testing machine
? This impact testing machine combines low temperature test and impact test in one machine.
? Adopts auto sample feeding device so that sample will be sent to do impact test once low temperature test is finished. This is done within 4 seconds to improve test precision and working efficiency.
? All the procudures (sample cooling, temperature holding, temperature adjust, raise pendulum, locate pendulum, sample sending, sample locating and impact) are electric auto control
? After breakage of sample, pendulum will raise with rest energy to prepare for the next test. Its super performance is suitable to the lab doing continuous low temperature impact test and to the metallurgy and engineering works doing large number of low temperature test.
? Test method: ASTM E23, EN 10045, ISO 148, ISO 83, etc.
