WS PM-7135

-DESCRIPTION

WS PM-7135 is a water-based pulp and paper antifoam for combating tenacious surface foam. It has excellent deaeration capabilities and also provides excellent performance in effluent systems and outfalls.

WS PM-7135 contains mineral spirits, poly-glycols and vinyl polymers in aqueous medium.

BENEFITS

• Economical water-based defoamer

• FDA authorized components

• alkylphenolethoxylate (APE)-free

• Readily disperses in process stream

• Minimizes surface foam and entrained air

• Effective paper mill antifoam

• Effective over a wide pH range

TYPICAL PROPERTIES (not to be considered specifications)

ACTIVE INGREDIENTS: 25%

FREEZE POINT : 32 °F/ 0 °C

DENSITY (20 0 C): 0.76 – 0.80 g/cm 3

APPEARANCE: Clear to slightly hazy colourless liquid

COMPOSITION: Solution of Silicone-Free Anti Foaming Agents.

PRODUCT APPLICATION

WS PM-7135 is dispersible from room temperature to boil. It is effective at very low concentrations. Ten to fifty ppm is a good starting point. The concentration can be adjusted to give the most economical concentration.

WS PM-7135 should be fed neat or diluted through a positive displacement dosing pump.

If separation occurs during storage, the product can be easily mixed using a drum mixer.

Proper treatment levels for WS PM-7135 depend on many factors, such as the severity of the problem, the type of furnish, machine speed, and other conditions particular to a given application. For most applications, the feed rate ranges between 0.25 and 2.0 lbs/ton (0.125 and 1.0 kg/tonne) of paper produced. Measurement of entrained air levels may be required to determine the most economical feed rate.

Specific feedpoints and feed rates will be established with the assistance of our Representative.

STABILITY

WS PM-7135 is stable in acid, alkaline, or neutral systems. Some of the recommended uses are in textiles, paper coatings, size mixes, printing ink manufacturing, wastewater ponds, and sewage systems.

WS PM-7135 is a very stable product, yet it releases its silicone very rapidly when added to the foaming media. As with most defoamers, best results are obtained by adding it to the system before foaming starts.

FDA STATUS

WS PM-7135 is manufactured in compliance with the regulations of the Food and Drug Administration as cited in 21 CFR, Section 176.200 (defoaming agents used in coatings) and Section 176.210 (defoaming agents used in the manufacture of paper and paperboard).

EPA STATUS

The ingredients in WS PM-7135 are listed in EPA Regulations, 40 CFR 180.1001(d), exempted from the requirements of a tolerance on growing crops.

STORAGE

WS PM-7135 should remain shelf stable for up to 12 months in its original, sealed container. To avoid freezing, store above 40oF. Product may separate upon freezing.
