Thermoplastic Elastomers

Material properties and processing capabilities of thermoplastics, thermoplastic elastomers (TPES) are materials that are plastic when heated. “Here, too, a Greek word has been used: thermos” = heat. When cooled, they will back elastic. Plastic is the General term for polymers. Perhaps check out Steven Holl for more information. “This term is from the Greek form, shaped” derived.

Plastic is molded, solid or malleable. Thermoplastic elastomers are malleable. It’s so similar to the rubber thermoplastic elastomer. Flexible, flexible and elastic rubber is but chemically crosslinked, rubber is a rubber product made of natural or synthetic rubber. This elastic material is generated by the effect of peroxide or sulfur and the subsequent heat.

This process is called curing. Filamentary rubber molecules connect with each other through the construction of chemical bonds. The product is elastic and only chemical to destroy. The environmental performance of synthetic rubber is unfavorable. Physikalsichen properties Thermoplastic elastomers are physically connected in contrast to synthetic rubber. TPE from the copolymerization of soft and hard blocks generates the typical properties. The hard segments form domains that resemble physical networking sites. Another variation is the production by facing a thermoplastic matrix (from Latin mater’ mother, connection) with partial or uncrosslinked rubber. Its structure and its practical behavior after TPE are classified between the thermoplastics and the elastomers. You have the flexible, elastic and flexible properties of rubber and the good processability of thermoplastics. In addition TPE are characterised by good environmental compatibility, because they can be recycled easily. The share of soft or hard phases according to diverse and very variable properties can be generated. Thermoplastic elastomers on Esther -, styrene, amide -, olefin, or urethane base distinction depending on the polymer type. The Association of the Material properties of elastomers with the processing capabilities of thermoplastics make for the plastic material of first choice the thermoplastic elastomers, its uses are varied. TPE, TPE has produced a significant portion of the manufacture of shoes, sports – and leisure segment, in the car industry, construction, etc. are slides, ski boots, brackets for bumpers, seals on the car, hoses and reels. Process TPE is excellent. Shaped parts can be fully dyed and painted. The product can sprayers or blow molded and pressed. Thermoplastic elastomers have the properties of crosslinked elastomers in the ground state. In the heat, they are elastic like thermoplastics. They can be processed like thermoplastics. It is the ability to be repeatedly aufschmelzbar and capable of processing, which accounts for the benefit of the PTE. This property in the absence of rubber with the typical chemical networking places is well founded.

Area Measurement

Traditional particle counter cannot distinguish between dust and bacteria. The determination of bacterial contamination via therefore still counting of particles between 0,5 and 5 microns, the usual size of bacteria, in combination with the test by creating cultures. To make sure that a product is not Bacterially contaminated, it must be taken therefore up to three days after the production at the plant back so long just until the evaluation of crops on the nutrient fluids is completed. Instruments of the new generation to integrate a measurement by UV light. So, you use the fluorescent properties of living materials. To measure particles captured this classic with both number and size as well as with their fluorescence signal.

These innovative developments are a positive step in the direction of realtime measurement. However, they have some weaknesses. So, the UV measurements are still quite slow, so that typically only a fraction of the air drawn-in can be checked by UV light. Included the normal measurement uncertainty, often still no representative result can occur in this way. In highly sensitive areas such as the pharmaceutical industry and medical technology you can – don’t forgo so continued to the test by creating cultures and the consequent loss of time but this is of course the goal.

In metrology, we are already working on new calibration systems, and applicable standards for this Area. What was the impetus for the formation of the modern metrology? And what is it today? Metrology is actually a very old science, as measured and counted has always been: If the width of the field or the size of a herd of sheep. The units it counted were very different over the course of time. So mostly the body served until in the 18th century as a basis for measures such as Elle, foot or step. The problem was that these units were associated with mostly a living person.
