Melamine is an organic compound that is often combined with formaldehyde to produce melamine resin, a synthetic polymer which is fire resistant and heat tolerant. Melamine resin is a very versatile material with a highly stable structure. Uses for melamine include whiteboards, floor tiles, kitchenware, fire retardant fabrics, and commercial filters. Melamine can be easily molded while warm, but will set into a fixed form. This property makes it ideally suited to certain industrial applications.
Melamine resin is manufactured by mixing urea with formaldehyde under heat and pressure. The substances begin to polymerize and are forced into a mold which will create the desired shape. Under pressure, melamine releases water, which could make the plastic unstable if it is not removed. The materials finish polymerizing and create a finished product, melamine resin.
Melamine resin is known as a thermoset plastic, because the plastic is fixed after molding. If exposed to enough heat, melamine will melt. For this reason, melamine dishware should not be exposed to high temperatures like those in the oven and microwave. However, the plastic is able to withstand higher temperatures than other plastics. Because it is a thermoset plastic, melamine resin is difficult to recycle.
Melamine can be made into a foam product. Melamine foam has a distinctive structure composed of stacked bubble shapes, which are extremely hard and therefore can easily clean a wide variety of substances. Melamine foam is marketed under a variety of commercial names including Magic Eraser, a cleaning tool well known for removing scuffs and dirt from a wide range of surfaces.
Melamine resin is used in Formica and similar construction products made from composite materials. Formica is made using melamine resin, which is used to coat the fibers in the upper layer of the construction product. The melamine resin makes the end result heat resistant, so that hot objects can be set on the counter without concern. The surface of the material is designed to be easily wiped and cleaned, creating a long lived household product.
Melamine also plays a role in a wide range of flame resistant materials. These include textiles used in upholstery and the uniforms worn by firemen. Thermal liners, heat resistant gloves, and aprons to protect from splashback of hot substances are made using melamine. Melamine will protect a wearer from heat hazards, and will help to resist the spread of fire in aircraft and buses by providing a fire blocker.
Melamine is also used in the manufacture of some filters. The material is porous and will admit substances to pass through, but can be used to filter out particles of a particular size. Melamine filters are capable of handling a high capacity and can be used in hot environments due to the heat resistance of melamine. Melamine filters are also extremely efficient.
Aside from common commercial uses, melamine became a topic of much discussion in early 2007, when veterinary scientists determined it to be the cause of hundreds of pet deaths, because of pet food contamination. Prior to these reports, melamine had been regarded as non-toxic or minimally toxic. However, because of the unexplained presence of melamine in wheat gluten added to mass-produced dog and cat foods, it is the most likely cause. Pet owners report symptoms that are commonly associated with renal failure, which could be explained by the ammonia that may result from the digestion of the melamine.

Avoid biscuits without labels: Health Ministry
KUALA LUMPUR: Biscuit lovers are advised not to buy loose biscuits from night markets, farmers’ markets and shops.
The Health Ministry’s Food Safety and Quality Division director Noraini Mohd Othman said this was to avoid buying biscuits that contained melamine exceeding the permissible level.
She said consumers must also be more alert to avoid food that could jeopardise their health and their family’s.
“We can only educate consumers, but they make the decisions when purchasing goods. Read the labels before buying.
“Don’t only think that loose biscuits are cheaper, but think of the effects the tainted biscuits have when we consume them,” said Noraini in a statement faxed to Bernama, here on Tuesday.
Noraini also advised retailers to be more responsible and to often check the ministry’s website to avoid selling food products tainted with melamine.
“If there is a food product that does not contain the permissible level of melamine, we hope they will remove it from the shelves or contact the District Health Office or State Health Department for more information.
“We also urge consumers to go through the list of products not approved by the ministry to avoid buying unsafe products,” she said.
The division today certified four products from China and four more biscuits from Malaysia to be safe for consumption.
The products from China are Hapi brand Strawberry Sandwich Biscuits, Jiahui brand Pizza Biscuits (Red Packet) and CHong brand Soda Biscuits (Green Packet) as well as Hichime brand fruit milk chew candy.
The four local products are Biskut Marie Kecil, Biskut Rokok S, Biskut Rokok L2 and Biskut Milk Fat Short Cake, all produced by Khian Guan. - Bernama

Star Fruit Can Kill - Beware !!
This is not an April Fool Joke. But a stern reminder to all my readers. We were advised to have a few servings of fruits a day in order to reap the benefits of fruits right? But obviously this is one big no-no fruit to be excluded from your fruity feast!
In Shenzen, more than 10 people who consumes the star fruit had died. And now a 66-year-old, Malaysian who has been suffering from kidney ailment fell into coma after eating the start fruits. Yes, all it takes is one fruit or 100ml of its juice and the ordinarily harmless star fruit transforms poison in a matter of hours for kidney patients. So does this mean, people without kidney problems should be fine with star fruit! My take: Not at all! Prevention is better right?
Universiti Malaya Medical Centre consultant nephrologist said that star fruits contain a neurotoxin which is not present in other fruits. It affects the brain and nerves. In healthy persons, the kidneys filter it out. But for those with kidney problems, this potent toxin cannot be removed and will worsen the consumers' conditions.
The symptoms of start fruit poisoning include:
~Hiccups
~Numbness and weakness
~Feeling confused
~Agitation
~Epileptic fits
The risk of death is high if you are having kidney ailments! But healthy individuals should beware of this fruit's potential toxin too. It could also cripple your vitality if you are not lucky. So don't take it for granted. It's better to avoid them. Please pass this news to others.

中風急救法
患了中風，腦部的微血管，會慢慢的破裂，遇到這種情形，千萬別慌，患者無論在什麼地方 …
《不管是浴室、臥房或客廳。》， 千萬不可搬動他。 因為，如果移動，會加速微血管的破裂。
所以要先原地把患者扶起坐穩以防止再摔倒，這時才開始 【放血】。
家中如有專為注射用的針，當然最好，如果沒有，就拿縫衣用的銅針，或是大頭針，用火燒一下消毒！
就在患者的十個手指頭尖兒《沒有固定穴道，大約距離手指甲一分之處。》 刺上去，要刺出血來 【萬一血不出來，可用手擠。】，
等十個手指頭都流出血來 《每指一滴》大約幾分鐘之後，患者就會自然清醒！
如果嘴也歪了，就拉他的耳朵，把耳朵拉紅，在兩耳的耳垂兒的部位，各刺兩針，也各流兩滴血，幾分鐘以後，嘴就恢復原狀了。
等患者一切恢復正常感覺沒有異狀時再送醫，就一定可以轉危為安，否則，若是急著抬上救護車送醫，經一路的顛跛震動恐怕還沒到醫院，他腦部微血管，差不多已經都破裂了。
萬一能夠吉人天相，保全老命，能像孫院長，容得勉強行動，那得要靠祖上的庇蔭了。
放血救命法，是住在新竹的中醫師夏伯挺 先生說的。且是經自己親身實驗，敢說百分之百有效。
大概是民國六十八年我在台中逢甲學院任教，有天上午，我正在上課，一位老師跑到我的教室上氣不接下氣的說：『 劉老師快來，主任中風了！』。
我立刻跑到三樓，看到陳幅添主任，氣色不正，語意模糊，嘴也歪了，很明顯的是中風了。 立即請工讀生到校門外的西藥房，買來一支注射用的針頭，就在陳主任十個手指頭上直刺。
等十個手指尖兒都見血了 《豆粒似的一滴》。
大約幾分鐘以後，陳主任的氣色就變過來了，兩眼也有神了，只有嘴還歪著，我就拉搓他的耳朵，使之充血，等把耳朵拉紅，就在左右耳垂之處，各刺兩針，待兩耳垂都流出兩滴血來，奇蹟就出現了！
大約不到三五分鐘，他的嘴形，恢復正常了，說話也清清楚楚了。
讓他靜坐一陣子，喝了一杯熱茶，才扶他下樓，開車送到惠華醫院，打一罐點滴，休息了一夜，第二天；就出院回學校上課了。 一切照常工作，毫無後遺症。
反觀一般腦中風患者，都是送醫院治療時，經過一路震盪血管急速破裂，以致多數患者一病不起，所以腦中風，在死因排行榜上高居第二位，其最幸運者，也僅能保住老命，而落得終身殘廢。
這是一個多麼可怕的病症。如果大家都能記住這 《放血救命》的方法，立刻施救，在短短時間它能起死回生，
而且保證百分之百的正常。
這個急救法，希望大家告訴大家。
那腦中風，在死因排行榜上，就可以除名了。
