Rubber band industry standards need to involve the following definitions , users can pre- professional knowledge as knowledge of its contents are summarized as follows : Compression strength: compression test, the specimen can withstand the maximum compressive stress ;
Melt flow rate: under the specified test conditions , a certain time the amount of extruded thermoplastic material ; Modulus of elasticity: the proportional limit , the stress and strain of the material corresponding ratio ; Plastic: with polymer as a main component , and in a stage of processing of the finished molding material can flow ; Rubber : to modified or modified so as not to dissolve , but can swell in boiling benzene, toluene, methyl ethyl ketone and ethanol azeotrope solvent such as elastomers, rubber modified , not under moderate pressure in the heating and re- molding , without a diluent, at standard room double length extends down to relax after 1 minute , can be retracted within 1 minute to 1.5 times the original length ; Curing temperature : The adhesive of the adhesive or assembly temperature curing ; Adhesive curing time : at a predetermined temperature or pressure or both conditions, an assembly time needed to cure the binder ; Curing time Plastics: Plastics sufficient time to harden ; Solids: determined under specified test conditions in a non- volatile substances percentage by mass ; Tensile strength: tensile fracture the maximum stress before , when the maximum stress occurs at the yield point, called the tensile yield strength, maximum stress at break , tensile strength at break is called ; Viscosity: stable within the fluid flow resistance display performance , the test liquid shear stress and shear rate is the ratio of the viscosity is often referred to as " Newtonian viscosity " At this point , the shear stress and shear strain ratio of a constant ; | |||
