Next, extinguish the flame and cautiously smell the fumes. 820 Compliant, FDA Master FTIR to ease problem solving (minimize failure, predict future cases in advance…) by gaining expertise in graph analysis to efficiently characterize your plastic materials. Resistant, USP Fluorine can be demonstrated by placing approximately 0.5 g of the plastic in a small test tube and pyrolyzing it in a Bun- sen fl ame. Each plastic product has a Plastic Identification Code — a triangle surrounding a number between 1 and 7 — usually on the bottom. One of the simplest ways to carry out a flame test is by cutting a sample from the plastic and igniting it in a fume cupboard. Plastics that don’t melt are called thermosets. Identification testing can also help a developer to compare several materials assisting the selection of the most suitable materials in terms of composition or quality. This is shown in the plastics Identification Chart. 800-444-3485 | Fax 361-594-2349 Identification of polymers by a flame test and spectroscopy is described. To initially determine whether a material is thermoset or thermoplastic, heat a stirring rod (to about 5000F/2600C, the material is a thermoplastic; if not, it is probably a thermoset. This liftgate spoiler has no plastic ID symbols, so we will have to identify the plastic by performing a weld test. Can it be scratched? This technique is used to sort plastics during the recycling process.
