| 773745 | 2009-05-14 10:17:00 | Hey Metla, you'll have to change that tag line, WWII was fought with plastic everywhere: The Story of Bakelite The first completely synthetic man-made substance was discovered in 1907, when Leo Baekeland, a New York chemist, developed a liquid resin that he named Bakelite. Baekeland had developed an apparatus - which he called a Bakelizer - that enabled him to vary heat and pressure precisely so as to control the reaction of volatile chemicals. Using this pot-like apparatus, Baekeland developed a new liquid (bakelite resin) that rapidly hardened and took the shape of its container. Once hardened, the resin would form an exact replica of any vessel that contained it. This new material would not burn, boil, melt, or dissolve in any commonly available acid or solvent. This meant that once it was firmly set, it would never change. This one benefit made it stand out from previous plastics. While celluloid-based substances could be melted down innumerable times and reformed, Bakelite was the first thermoset plastic which would retain its shape and form under any circumstances. Bakelite could be added to almost any material - such as softwood - and instantly make it more durable and effective. Numerous products began to be manufactured based on this new material. One of the sectors of society most interested in its development was the military. The US Government saw Bakelite opening the door to production of new weaponry and lightweight war machinery that steel could not match. In fact, Bakelite was a key ingredient in most of the weapons used in the Second World War. Bakelite was also used for domestic purposes such as electrical insulators. For this purpose it proved to be more effective than any other material available - so effective, in fact, that it is still used as such today. Bakelite is electrically resistant, chemically stable, heat-resistant, shatter-proof and neither cracks, fades, creases, nor discolours from exposure to sunlight, dampness or sea salt.

| 773747 | 2009-05-14 10:30:00 | Hey Metla, you'll have to change that tag line, WWII was fought with plastic everywhere: Cheers Billy 8-{) ;) Interesting. Though truth be told the claim about plastics was made by Terry. I used it as my sig as its such an absurd point to make whether its true or not. |

| 773748 | 2009-05-14 10:40:00 | Too true Metla, it is an absurd point and I rather like it as a tag anyway. Rayon, Nylon, PVC, Polyethylene and Cellophane were also around in WWII, plus a few more more doubt. Some date back to the 1800's, but as laboratory curiosities though, not for commercial use. If it hadn't been for nylons, the Yanks wouldn't have scored quite so well with the girls in WWII either. Cheers Billy 8-{) |

| 773749 | 2009-05-14 10:43:00 | Coming out of invisibilty, yes Billy, we all know that bakelite goes way back, I have a 1932 ECKO TRF set that's been in the family from new. Bakelite doesn't count. Ebonite in various forms was also widely used in WW2, made from rubber, used for making fountain pens also, most of the black 'plastic' boxes and black insulating materials widely used in aircraft were rubber/ebonite based. There were also phenol and formaldehyde resins and waterproof adhesives, but they dont count either. No, I was talking about the polyethylenes, nylons, ptfe, polyesters pvc ,etc, although some invented during or before WW2 did not come into widespread use until after the war. WW2 was fought almost entirely without the modern day plastics that we take for granted :) Just read your post Billy, I suppose you could say that the Yanks won the girly war with nylon stockings, but nylon as a solid plastic was almost not used. Cellophane and cellulose products were in use for years before WW2, but do not qualify as there were derived from natural products rather than from synthetics. |

| 773750 | 2009-05-14 11:02:00 | Not sure about Bakelite not discoloring etc, ever been in an old car like an old Ford Anglia on a rainy day and the steering wheel, dash and window trim are all sticky. And the **** is fragile like it cracks if you overtighten the screw holding the trim on. I dont think phenol based stuff could be classified as plastic because its so rigid. |

| 773752 | 2009-05-14 11:23:00 | WWII was fought virtually entirely without invisible mode....wow ! | --Wolf-- (128) | ||
| 773753 | 2009-05-14 20:48:00 | From 'invisible mode' to bakelite. How on earth. It was Billy's fault, he hadn't read the thread that prompted Mets signature pressf1.pcworld.co.nz otherwise he would have read that bakelite was mentioned early on in the thread. The use of the generic word 'plastic' such as in the phrase "it's made of plastic" didn't even exist in WW2, there were no plastic bags, or plastic wrapping, there was no widespread use of 'plastic' as we know it today. If Mets thinks it is absurd to comment along these lines then he is entitled to his opinion..............:lol: |
