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:Ig is what kind of food additive
- Is I + G, is a mixture of 5 'inosinic acid sodium and 5' Nucleocapsidate. Is better than the monosodium glutamate glutamic acid is difficult to mention a better fresh agent, one of the ingredients in the chicken.
- Q:What are the types of paint additives?
- User's answer more types of additives. Commonly used hardeners, retarders, matting agents and softeners. The additive used to accelerate the hardening and increase the gloss is called the hardener; the slow drying is called the retarder; the matte weaker is called the matting agent; the elasticity for the paint layer is called the softener.
- Q:(In Australia)What‘s that new diesel fuel additive everyone‘s talking about that is supposed to be the ducks nuts? Octane/Cetane booster?I head a diesel fitter at work talking about how the freighting companies are using it in their trucks and getting another load of freight with the same amount of fuel.Cheers.
- well from what ive learned, Those additives havent been proven to work, unconfirmed reports not lab tested of only 1/2 mpg or less. i have heard that true fuel savings are achieved by proper tire inflation, slowing down so the rpms match the gear ratio and tire rpm. i think the formula is something like engine rpm X gear ratios X tire size X tire rpm divided by 60. ( this might not be right) i am interested to see the correct answer your looking for, im willing to try it and see but nothing ive heard or tried truely works
- Q:I want to know why they have so many and are they really necessary. is there a list that says what they are AND their purpose of each one?
- what the shop said you pretty much need to strip and/or replace the entire brake system. Its a big job. Oh and for the love of god do not just flush the brake lines and refill with brake fluid. the power steering fluid will have most likely ruined all the seals in your brake system. even if it does fix it now, you'll regret it when the seals give way and you're screaming down the freeway with no brakes.
- Q:main additives of lubricants?
- There are different additives for different things. Antioxidants to reduce thermal and mechanical decomposition. These are usually sterically hindered phenols and thiophenols. Thickeners which are usually lithium salts of fatty acids. Friction reducers which include P2S5 and various fatty acid thiophoshate esters. Corrosion inhibitors such as imidazolines.
- Q:I have been told most gasolines have an additive to remove water??
- That is kind of a complex question actually. At the supply end of gasoline they sometimes put additives (demulsifiers) in to make the water fall out of gasoline so they can draw it off the bottom of the supply tanks. Hydrocarbons will absorb a certain amount of water and keep it entrained at different temperatures (all based on the saturation point). Most gasoline now has ethanol added at the truck rack before it goes to the gas stations. Ethanol will help the gasoline absorb water. A little bit of water isn't going to hurt anything as the car will just run it through with the gasoline, however large amounts of water can become problematic. If there's enough water in the gas to fall out and start forming water puddles on the bottom of your tank you can have a problem with your car trying to suck pure water through the system which obviously won't work too well. By adding a gas line drier to your fuel you will help it absorb the water and pass it on through with the fuel. If there's too much water you will need to try to drain the bottom off of your gas tank to remove it. This is the reason I tell everyone I know NOT to buy gasoline at a station where a truck is dropping fuel. All of the water that had fallen out of the fuel to the bottom of the tank is now being stirred into the rest of the gasoline and may take a couple of hours to fall back out. If you buy gas while the truck is discharging you stand a chance of getting some of the water that was on the bottom of the tank. They will tell you there's filters in the pumps to separate out the water before it gets to your car but they are not 100% effective.
- Q:Food additives in dairy and dairy products?
- There are many different additives to many types of dairy products. As an example all milk has to be pasteurized. Cheese has rennet added yogurt has additives. Although here in N.Z, there is a drive by the consumer to purchasing raw milk, as the processing of the milk causes alarm to some. There is additives added to many different types of dairy products.
- Q:1) 0.42) -1.63) - 11/164) 5 and 5/6
- Air usually only gets in the system if you change the master cylinder, brake calipers, or brake lines. If you properly bled your brakes when they were installed, then there should be no reason to bleed them further.
- Q:What is the amount of methanol gasoline additive?
- Methanol is best to use 99.9% purity and pure burning, blending blending with gasoline! Additives the best is ferrocene, methanol, heat absorption than gasoline, better than the gas to improve the safety of the engine better!
- Q:how good is prolong oil additives?
- I don't know if prolong is a name brand additive or just an additive. I do not advise using additives, however, If you are talking about something to give you better mileage and less wear on your engine I would say full synthetic and I still would never go longer between oil changes as although synthetic moisture and contaminants can still get in your oil. You maybe can go up to 5,000 miles the most I would personally recommend. If I am not answering the question just ignore it and I am sure you will get the correct answer.
