Talk:Thermoplastic elastomer

Microstructure
I have added some pictures of TPE's to provide some basic underpinning of the topic. They help to explain why block copolymers have such interesting and useful physical properties Peterlewis (talk) 23:33, 4 March 2008 (UTC)

Dear all,

Could you please tell me what is the difference between TPE and TPR. It seems that TPR is under a group of TPE. Because the TPE can make in plastic or rubber. Actually, I do not know what is the property difference and cost difference between TPE and TPR. Can anyone help me. —Preceding unsigned comment added by 203.223.203.138 (talk) 18:01, 17 July 2008 (UTC)

Dear all,

Could you please tell me that is there any posibility of smell in thermo plastic rubber after mixing some recycled thermo plastic rubber.Somebody help me please. —Preceding unsigned comment added by 122.160.251.50 (talk) 12:27, 8 July 2010 (UTC)

Merge proposal
I am assuming that Thermoplastic elastomer and Thermoplastic rubber are synonyms. Is this correct? Biscuittin (talk) 17:57, 31 July 2011 (UTC)

Rubber and Elastomers are different http://www.dowcorning.com/content/discover/trivia-diff-elast-rubber.aspx — Preceding unsigned comment added by 107.20.180.134 (talk) 17:09, 8 June 2012 (UTC)
 * Did you read your source? It's pretty clear that rubber and elastomer now mean the same thing, while they did not, historically. It's been almost 1 year since merge was proposed; I'll do it when I find the time, unless there are more objections or someone beats me to the merge. Rgambord (talk) 00:17, 1 July 2012 (UTC)

Content from merged article thermoplastic rubber
Thermoplastic Elastomers (TPE’s) have gained notable attention due to a combination of their rubbery properties, such as low compression set, high flexibility, resistance to fatigue, and heat resistance. Their thermoplastic nature, including extrusion and injection molding as well as their simple preparation method also contribute to their popularity. The microstructure of TPE’s consists of a continuous phase thermoplastic matrix that also contains a dispersed rubber phase. As with TPU’s, TPE’s have also been widely used for various applications in automotive parts, electrical and medical industries, and packaging. This increased use may be due to their demonstrated endurance, their low density, and their relatively low manufacturing cost. TPE’s can be re-processed and reused. Most of these industry leaders believe this will greatly reduce production costs and liabilities associated with accumulating scrap and disposal. Fillers such as glass fiber, carbon black, talc, and calcium carbonate (at high loading levels) can improve the mechanical properties of TPE blends such as stiffness, heat distortion temperature, and dimensional constancy. However, when these fillers are added, it increases the weight of the TPE blends. This often makes them less desirable for automotive and aerospace applications.

The mechanical properties of TPE’s depend on the properties of the individual components in the blend and on their respective concentrations in the materials. Polyamides can be used as crystalline polymers, which have outstanding mechanical properties. These properties include rigidity, wear resistance, and corrosion resistance for common applications. Polyamides can also be blended with elastomers to improve their impact strength and mechanical properties. Rgambord (talk) 00:42, 1 July 2012 (UTC)

Love Doll Application
TPE is now widely used as realistic skin in the highest-end ($700+) realistic love dolls (or sex dolls). This should be mentioned in the "Applications" section as the use of TPE has outstripped any other artificial love doll skin in terms of durability and realistic feel.

Some proposed changes
Information to be added or removed: Please add the below section ("Biodegradables") after the "Processing" section using this study as a reference.

Biodegradables
There are also thermoplastic elastomer materials on the market certified as compostable according to ASTM D6400 and EN 13432. These standards certify that a plastic material will disintegrate within 12 weeks and biodegrade within six months in an industrial composting facility.

Biodegradable thermoplastic elastomers exhibit similar processing characteristics as their conventional counterparts, though the resin must be dried prior to processing. Processing temperatures must be kept under about 400° Fahrenheit to prevent shearing, or the buildup of friction which can cause biocomposites to burn, discolor and degrade. In injection molding, lower injection speeds and larger gates and runners can also work to alleviate shear buildup during processing. Biodegradable thermoplastic elastomers can also be processed using blow molding, blown film, sheet extrusion and profile extrusion.

Biodegradable thermoplastic elastomers can be compounded with other bioplastics to achieve any number of desired performance properties. For example, biodegradable thermoplastic elastomers are a good impact modifier for polylactic acid (PLA), a common bio-based and biodegradable polyester. When combined with PLA at a ratio of 30%, biodegradable thermoplastic elastomers have been proven to increase the impact strength of PLA by more than 400%.

Explanation of issue: This page does not discuss the emerging category of biodegradable thermoplastic elastomers, and this added section allows the page to be current.

Your edit request could not be reviewed because the request is not formatted correctly. In the collapsed section below titled Request edit examples, I have illustrated two: The first shows how the edit request was submitted; the second shows how requests should be submitted in the future.
 * 1) The citation style predominantly used by the Thermoplastic elastomer article appears to be Citation Style 1. The citation style used in the edit request consists of bare URL's. Any requested edit of yours which may be implemented will need to resemble the current style already in use in the article – in this case, CS1. (See WP:CITEVAR.)
 * 2) Citation ref tags have not been placed within the requested text indicating which portions of the text the source is referencing. (See WP:INTEGRITY.)

Incorrectly formatted request: The Sun's diameter is 864,337.3 miles, while the Moon's diameter is 2,159 miles. The Sun's temperature is 5,778 degrees Kelvin.

In the example above there are three URL's provided with the claim statements, but these URL's have not been placed using Citation Style 1, which is the style predominantly used by the Thermoplastic elastomer article. Additionally, the ref tags have not been placed within the text at the exact positions where the information they reference resides. Using the correct style and the correct positioning of the ref tags, the WikiFormatted text would resemble the following:

Correctly formatted request: Please add the following sentence to the first paragraph of the article's "Sun and Moon" section: The Sun's diameter is 864,337.3 miles, while the Moon's diameter is 2,159 miles. The Sun's temperature is 5,778 degrees Kelvin. Which displays as: Please add the following sentence to the first paragraph of the article's "Sun and Moon" section:
 * The Sun's diameter is 864,337.3 miles,[1] while the Moon's diameter is 2,159 miles.[2] The Sun's temperature is 5,778 degrees Kelvin.[3]

In the example above the references have been formatted according to Citation Style 1, which shows the author, the source's name, date, etc. Also, the ref tags are placed in the exact location where the text which they reference resides. As Wikipedia is a volunteer project, edit requests such yours are generally expected to have this formatting done before the request is submitted for review.

Kindly rewrite your edit request so that it aligns more with the second example shown in the collapsed section above, and feel free to re-submit that edit request at your earliest convenience. If you have any questions about this formatting please don't hesitate to ask myself or another editor. Regards,  Spintendo   22:07, 26 November 2018 (UTC)

Missing information on "Disadvantages"
There is an Advantages section, but no Disadvantages. And there are disadvantages, such as the way TPE melts and becomes sticky on consumer items like cameras and car interiors. Search YoutTube for "melting dashboard" or "sticky dashboard" to see how widespread this is, and what a disaster TPE has been for consumers. I am not able to find studies detailing these problems, but materials science is not my area so I leave it to others to investigate. Ratel (talk) 21:23, 25 January 2020 (UTC)
