Product introduction

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.

The Statue of Liberty
Q:additives that is used in an food
what do you mean by additive huh cyanide is an additive do you mean the ones that are known to be harmful and still included bcoz they are a cheaper alternative tobacco is bad for you, either chewing or smoking it, only now are they putting warnings on it for its danger
Q:What Is the relationship between additive and synergistic effect with bacteria and antibiotics?
it will be non-stop barking and alarms and you'll have lots of pissed off neighbors
Q:whats the best automotive oil additive?
After 40 years in the biz, this is still my pet peeve! There is no best additive. Period. Change your oil according to the recommendation of your car's manufacturer. Additives rarely do any good, and many can mess up your engine big time! . Beware of Slick 50 it has been banned in some states and no car company recommends using it. Slick, like some other brands, contains silicone and Teflon, which can clog up your oil filter and makes things worse. Additives containing graphite are also as bad as slick because it coats the inside of your engine and clogs the small oil galleys and passageways. Coating the inside of your engine block doesn't lubricate anything, and in fact decreases the blocks ability to conduct heat away from the moving parts. . Modern car engines have zero tolerance parts. This means there is no slop in the moving parts like bearings and rings. If your oil is too thick, these close fitting parts don't get lubricated properly. For this reason, STP is no longer recommended in modern car engines. . Race cars use special additives, but then the owners tear the engines down between races. They don't drive their cars back and forth to work like you do, which is really hard on an engine. , So. Stick with a good grade of oil, of the proper viscosity and change your oil and filter at least twice a year.
Q:well when i start the car in the morning or if it sits for a while,it will smoke then clear up.so i put in a stop oil burning additive in the car.( stuff was for 4 cyl engines,which it is)and did not over fill engine.well the next day with less than 15 miles on engine with the additive in the car i went to a friends to change tires.so the car sat for about a half hour.when i started the car it really smoked bad and did for a few days when i started it up in the morning or let it sit for a while.it would clear up but it definitely is smoking worse.so i talked to a notable mechanic and explained the situation to him and he said the additive i put in was the cause and i should change my oil and filter,so i did.the name of the additive was RESTORE a name brand additive.whats your thoughts on this?of course since i just changed the oil and really have not driven the car to see if that will work.but tomorrow i should get some results.thanks for any help.
Additives really don't work all that well to fix oil control problems. Oil control problems and smoking are usually due to bad/ leaking valve seals, or worn piston rings. You don't mention the age of the vehicle or the mileage, so I would have your mechanic do a compression test to identify the problem.
Q:I always see the fuel additives at the gas station. Do they really work to help keep your fuel injection working properly?
No, they will hurt actually. The only additive I would suggest is Techron by Chevron. All the others will leave what looks like a red dust like deposite on your spark plugs, valve faces, and the EGR valve. I once worked on a Mustang GT (1999) that the EGR was almost completely stoped up with this red deposite crud. Techron is the way to go.
Q:I use gasohol in my car. Is it necessary to use gasoline additive, to keep the gas from freezing?
I have the same problem in our home with the well water. I just replace the copper as it happens.in the longest runs possible. Plastic pipe yuck
Q:(1) 0(2) 1(3) -1(4) there is no such real number
I think the last time I changed them was in 1979!!!!! Wow! Maybe it's time!
Q:Fruit and mineral water
Looks like no, all the packaging of food, will contain a certain amount of additives, if not, and only their own hands at home to do the natural bar, in fact, as long as the amount of food additives, will not be harmful to the human body.Moreover, no food Additives, food will not have our favorite color scent.
Q:Is soy dietary fiber a food additive?
No, soy dietary fiber is a kind of dietary fiber, in the classification, all the dietary fiber belongs to a can not be digested carbohydrates and carbohydrates in the classification of food raw materials, and flour, sugar, etc. belong to a Classification grade, does not belong to food additives.
