What does pp mean
I. PP (polypropylene polymer) generally refers to polypropylene.
Polypropylene, is a polymer of propylene through the polymerization reaction. Department of white waxy material, transparent and light appearance. Chemical formula for (C3H6)n, density 0.89 ~ 0.91g/cm3, flammable, melting point 189 ℃, in 155 ℃ around the softening, the use of temperature range of -30 ~ 140 ℃.
Below 80 ℃ can resist acid, alkali, salt liquid and a variety of organic solvents, can be decomposed at high temperatures and oxidation. Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, conveying pipelines, chemical containers and other production, but also for food and drug packaging.
Two, pp is the protection profile, protection profile of the abbreviation, refers to meet the specific user needs, a class of TOE (assessment of the object), and the realization of a set of independent of the safety requirements.
Three, Positive assumptions, that is, positive assumptions, the face of the problem and interpersonal relationships in a positive direction. For example, if you are late for a meeting with someone, you may think that I am too early, or that he has deliberately given me some time to prepare for the meeting, or that he has encountered something he can't get away from.

Four, PP (Japanese: PP, English: PP), the full name of the move points (tentative translation, Japanese: パワーポイント, English: Power Point), explains the number of times a move can be used.
V.PP is the abbreviation of "percent point" or "percentage point". And % comparison, is to identify the "absolute value of the change"
that is, percent point or percentage point, abbreviated PP, meaning percentage point. For example, the government work report this year, the employment rate of college students reached 74%, next year is planned to increase 5pp, that is, next year, the employment rate of college students is planned to increase by 5 percentage points (to 79%).
Note the difference between its and percent (percent), for example: 40% -> 44%, is an increase of 4 percentage points (4 pp), but corresponds to an increase of 10 percent (10%, 10 percent).
Sixth, PP (Production Planning) module, the Chinese name for the production planning module.
PP module in SAP belongs to one of the logistics module, it and the MM module, SD module together constitute the most basic production enterprise production, supply and marketing system.
The PP module assists the entire company, from the production manager to the operator, in planning the production process. For example, it can plan the transportation and storage of raw materials, production equipment, by-products, and waste products. A graphical representation of the production process shows the relationships between the various stages of production and provides the information needed for planning, control, and documentation of production.
The PP module generates a production order that summarizes cost, material, process, quantity, and schedule information. PP meets the operational requirements of manufacturers whose business processes are constantly changing and evolving. It provides the ideal solution for the three areas of production planning, production execution and production control. In the PP module, demand management, material requirements planning, production control and billing are the functions that are more commonly used by companies.
VII, ?pp (abbreviation of vitamin PP) generally refers to niacin.
Nicotinic acid belongs to the vitamin B family, also known as niacin, vitamin B3, anti-mangement factor, molecular formula for C6H5NO2, the chemical name of the pyridine-3-carboxylic acid, thermally stable, can be sublimated, the industry is often used in the sublimation method of purification of niacin. Niacin appearance of white crystals or white crystalline powder, soluble in water, mainly in animal organs, muscle tissue, fruit, egg yolks also exist in trace amounts, is one of the body's 13 essential vitamins.
At present, niacin is mainly used in feed additives, which can improve the utilization rate of feed protein, increase milk production of dairy cows and fish, chickens, ducks, cows, sheep and other livestock meat production and quality. Niacin is also a widely used pharmaceutical intermediates, with its raw materials, you can synthesize a variety of pharmaceuticals, such as nicosamide and nicotinic acid inositol ester. In addition, nicotinic acid also plays an irreplaceable role in luminescent materials, dyes, electroplating industry and other fields.
Eight, Payback Period, abbreviated PP, means payback period.
The payback period is the time required to recover the investment through the net cash flow of the project, generally calculated in years.
The calculation of the payback period varies depending on whether the net cash flows from operations are equal each year.
If the annual net cash flows from operations are equal, the formula is.
PP = initial investment/annual net cash flow.
If the annual net cash flows are not equal, the formula for calculating the payback period is determined based on the amount of investment not yet recovered at the end of each year. The formula is:
PP=the year in which the cumulative net cash flow is positive-1+the absolute value of the cumulative net cash flow of the previous year/the current year's net cash flow.
Nine, PP (Thai actor, singer) generally refers to Krit Anu Aidchikorn.
