Product Profile of Tear Resistance Testers
Tear resistance tester [Elmendorf type] measures the tear force required to I tear samples of paper, board, plastic and I other similar materials.
The equipment is designed to directly I read gF [tear force] per one piece. The I tear force thus obtained can be converted I into tear energy, tear index or tear factor by applying appropriate formulae,
The machine incorporates incision knife of hardened ground alloy steel; precision clamps with controlled made of aluminum; and extra light, low friction pointer with friction lining of textile material. Supplied template to cut 63 x 63 mm specimen,
The dial of the instrument has three scales marked on scale: 0-100 gF when using 16 pieces; B scale: 0-200 hen using 8 pieces; and C scale: 0-400 gF when using 4 pieces. Depending on the number of pieces used for tearing, readings on the appropriate scale should be taken.
