PARTIL HYDROLYTIC POLYCRYLAMIDEPHPA （liquid）
————————————————————————————————————————————

Description

This product is a medium charge anionic polyacrylamide in emulsion from that is used as a flocculant in a wide variety of municipal and industrial wastewater treatment application. It has been successfully applied in all liquid/solid separation systems including clarification, thickening, and dewatering.

Quality Specification

Item	Result
Physical Form	Clear to milky white liquid
Anionicity	30%
Active (%)	29
Freezing Point (%)	7℉(-14℃)
Flash Point	＞200℉ (＞93℃)
Density	8.7-8.9

Usage & Dosage

This product must be pre-diluted in water before use. It should not be applied neat. One method for dilution is adding the neat polymer into the vortex of a mixed tank at a concentration between 0.25-1.0% polymers (0.5%is optimum) by weight.

PACKAGE

The product is usually kept in plastic drum, with each net weight 25 KG or 55gallon; Special packages are available based on customers' requirements.

STORAGE

Suggested in-plant storage life is 6months in opened drums. For best results, store at 50-80℉. Drums and bins should be mixed very well before first use and weekly after that. Do not allow emulsion polymers to freeze. Should freezing occur, allow the product to thaw thoroughly in a heated area and mix well before attempting to use it. For spills of this product, sprinkle vermiculite or equivalent obsorbent over the spill area and sweep thee material into approved chemical disposal containers. Do not spray water onto a spill because the resulting gel is very difficult to clean up.

SAFETY

Avoid contacting with eyes, skin and clothing. Otherwise, wash with a flush of water. Refer to Material Safety Data Sheet (MSDS) for complete handling and hazard data.
