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.

- Q: What is SPF? Is it kinda additive?
- SPF Sun protection factor. It's just a number scale that indicates how much longer you can stay in the sun without getting burned as opposed to wearing no sunscreen at all. For example, an SPF of 15 means you can (supposedly) stay in the sun 15 times longer than you normally can without burning, but that assumes that you don't lose the protection by swimming or sweating. Not sure what pharmaceutical companies add to sunscreen to increase the SPF though.
- Q: Which expression is the multiplicative identity of -3(a ? b)? A.0 B. 1 C. 3(a ? b) D. -3a + 3b
- The product of a number and its multiplicative identity just returns the original number. So the multiplicative identity of any number is 1. We can justify this by saying that any number (except zero) divided by itself is 1: a/a 1 and therefore a 1*a. The additive inverse is the number that when added to the original number gives zero. In other words, it would be the negative of the original number. The additive inverse for -3(a-b) is -(-3(a-b)) 3(a-b).
- Q: what is the difference between inverse and additive inverse on rational numbers?
- Hi Inverse most probably refers to the reciprocal of the rational number. Additive inverse is the number, which when added to the original number, gives zero. For example: For 3, inverse is 1/3 and additive inverse is -3.
- Q: Tofu for what additives

- Q: proof of additive inverse, -(-a)a. By using a+(-a)0?
- Well.because modern torque converters (automatic) are superior to manuals in hp efficiency. .it could be caused by under drive gear ratio differencesor even overdrive gear ratio differences.unless the automatic can engage a converter lock up clutch on the get go.the manual has the advantage on the starting lineI guess it would depend on when the manual overcame the automatic in the race.
