Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether, made by natural high polymer cellulose as raw material and series of chemical processing. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.
It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

Gypsum Filler/Joint Filler
Gypsum filler or Joint filler is a dry mixed mortar that is used to fill the joints between wall boards.
Gypsum filler consists of hemihydrate gypsum as a binder, some fillers and additives.
In this application, HPMC provides strong tape adhesion power, easy workability, and high water retention etc.
Recommend grades: HPMC 75SS-K (100000mpa.s)
- Q: I bought an 85 Ford F-150 a few weeks ago. The dealer told me it had been sitting a long time. It had an oil leak and the mechanic told me to put this additive in that would make the seals expand. I did it and now I have many leaks! Why is that and what should I do?
- whereever its leaking from you will have to fix or buy a new engine. you basiclly answered your question. as the additive makes the seals expand, its like making a hole bigger and more will come out. most additives are thinner and the additive should have been to seal the leak until you can fix the seals. they are really cheap and you can do it yourself. by sitting a long time, sludge build-up is in the pan and put back in the engine. upper engine sludge means problems and a new engine.
- Q: Hey all, we are doing a debate in class and i am against food Additives. Can you help me out and name a couple of things why food additives are bad. plz help. thanks. ;]
- Many things are added to food, and unless you read the label, you may be unaware of what you are eating! Commonly used additives include preservatives that prevent or inhibit spoilage of food due to fungi, bacteria and other microorganisms, humectants that prevent foods from drying out, antioxidants (like vitamin C) which act as preservatives by inhibiting the effects of oxygen on food (and are beneficial to health), and emulsifiers that allow water and oils to remain mixed together in an emulsion, as in mayonnaise, ice cream, and homogenized milk. Additives are bad because they make our food more stable and fresher, so people do not get the benefits that derive from moldy or stale food.
- Q: I need a lead fuel additive/octane booster for a 1966 Ford Mustang. What brand should I purchase?
- 104+brand additives work very well when used as directed
- Q: Is a polaroid photograph considered additive or subtractive color?
- Photographic prints (including Polaroids) do not emit light. All photographic prints are viewed via reflected light (subtractive color). In other words, the light is reflecting off a surface. Light hits the surface and some photons of particular wavelengths are absorbed by the object (or pigments) while others are reflected - this is what gives a solid object colour. Anything else that shows colour by reflected light is also using subtractive color. That would include any solid (non-transparent) object in the real world too, including paper with ink or paint on it. Computer screens and TVs emit colored light (additive color).
- Q: i need help on my math homework. I do not understand this question. Anyone know the answer???
- Just negate the number The additive inverse of 39 is -39 The additive inverse of -4 is +4
- Q: What additives can be used in concrete during hot weather.?What additives can be used in concrete duringcold weather?
- you need to learn how to use that front brake! both set of pads sould wear out at the same time, usually I wear my front out before my rears ;) could be from all the front stoppies too I guess
- Q: Give examples of food which contain themcan they be dangerous?
- I refer you also to my answer about ANTIOXIDANTS. ALL additives to food are present for a purpose: To add colour or to retain a colour; as a preservative; flavouring enhancers and emulsifying agents. There are strict laws here in England which prevent our foods from having any known dangerous additives, however although some additives are known to be harmful (like certainE" numbers which are chemically produced) others are not harmful to us, proportionally as they sourced from natural products. One can get too worried at times thinking about the lists of additives (which can be found printed upon most food lables, such as frozen products etc.) but unless you are a bio-chemist, it is hard to know what is what? A good way to know if there arwe any additives present, is by reading the main food or drink description:ORANGE FLAVOUR DRINK" for example, will probably contain NO ACTUAL ORANGES at all. The wordFLAVOUR" in the drinks title is a the give-away! Get me? The above drink would have been produced from flavourings alone and also colouring so as to taste and appear to be orange, whilst it is not! Chocolate Flavour? Coffee Flavour? Blueberry Flavour? NONE of these are natural. The flavouring of these foods will be provided by an additive and we all of us have been eating & drinking these so-called foodstuffs for many years! Hopefully without any detrimental harm to ourselves??
- Q: single trait cross double trait cross codominant polygenic none of the above .
- polygenic Poly many, genic genes. When many (2+) genes contribute in an additive manner, it is a polygenic trait. Skin pigmentation is a good example. The more 'dark' alleles one has for the genes controlling melanin, the darker the skin. In codominance, two (or more) genes are all expressed, but not in an additive manner. Roan cattle have both red and white hair. Both the red and the white genes are expressed, but not additively.
- Q: I put a bottle of the fuel additive in my gas tank and then drove to the gas station (About 1 mile or less away). When I got to the gas station, I filled up my tank. But on the way to the gas station, I noticed that my car started hesitating and not accelerating as normal. Then my check enpermanentlycame on! I hope I didn't permanently damage anything It does fine after the initial hesitation. Do you think it just needs to run through the tank of gas?
- ive always use the stuff since it came out i add it every time i think about it and it dont have to be added to a full tank of gas . it will not hurt anything if anything your car wasnt running right to began with. so have you change the fuel filter might help also. doesnt hurt anything at all
- Q: What is the additive identity property?
- it might be mis-firing. no one will really know till you get it checked. and anytime your check engine light comes on, it's because of a sensor that set it off also, you can take it to autozone or advanced auto parts to have it checked for free.
