A three step process
Tensile testing is a common method used to measure the strength of plastics and polymer materials. Tensile or tension testing measures the extent of force required to stretch a plastic specimen until its breaking point. When deciding how to configure test equipment for tensile testing a plastic, you can follow a simple three step process:
The first step to your planning process is to gather background information on the types of plastic samples you plan to test. The type of material indicates strength which helps us establish the right size of test machine. Plastics are wide and varied and include abs, acrylic, biomaterials, bioresorbable plastics, ceramics, fabric strip polyolefin plastic, fiber reinforced polymer composite, flouroplastics, cellular foam, glass fibre fiber reinforced, HDPE, high density polymer, plastic adhesive, plastic coated, polybenzoxazole, polycarbonate, polyester thread, polyester tire, polymer clay, polypropylene rope, polypropylene tape, polystyrene, polyurea, polyurethane composite, polyurethane foam, PVC plastics, single carbon fiber composites, thermoplastics and more.
Are you testing plastic components? It is important to plan for your test sample form because it establishes test fixture requirements. Plastic products include wood, tubing bonds, tubing, tubes, thin film, strip, strapping, strap weld, springs, spool, specimen, sheet, screw, ring, rigid foam, rectangular, rebar, plastic rod, plastic dog bone specimens, parallel strip, packages, orthodontic brackets, monofilament, molded, miniaturized, mesh, medical devices, laminate, foils, flatwise, fiber mesh, dumbbell, double sided notch, dogbone, crates, cord, chain, cable ties, bottles, bolts, bar, bandages, and bags.
After determining the type and form that you plan to test, the next step is to define the best test type or method for tensile testing your material or product. This choice may vary depending on what type of plastic you are testing and what sort of results you are looking to receive. Testing variations include tensile adhesion, bending, torsion, tensile bond strength, tensile break strength, burst, elevated temperature, tension fatigue, friction, high speed, high strain rate, hysteresis, impact, low temperature mechanical properties, microtensile, polymer, polymer tensile peel yield, puncture, ratio, seal, shear stress, shear tensile, stretching, tear resistance, tensile shear, tensile strength, or tensile torsion.
The next step is to determine the information or test data that you want on your test report. This is important information for both you and a testing engineer to select test software. You may need a wide variety of data including youngs modulus, yield strength, ultimate, tensile stress, tensile strength, tensile modulus, stress strain, strain rate, speed, shear, secant modulus, pull rate, protocol, property, MPA, modulus, load rate, load, KSC, hoop tensile, high tensile strength, gauge length, flexural strength, flex stress, flex modulus, elongation at break, elongation, elongation, dynamic, dimension, destructive, deformation, curve, compressive tensile stress, comparison, compare flexural and tensile, calculation, breaking polymer bond, biaxial, yield break, stress strain, specimen dimension are all available with the correct test machine configuration.
After determining the type of plastic, the type of test and the necessary data, you will have enough information to move forward to the process. Armed with these essential facts, you will be able to choose the proper testing equipment. Our applications engineers are awaiting your call today to help determine your further testing needs.
