[performance and application]

1, as low foam detergent or anti foam agent

L61, L64, F68 for the preparation of low foam, high detergent synthetic detergent;
L61 is used as a foaming agent in the paper industry or fermentation industry;
F68 is used as an anti foaming agent in the blood circulation of artificial heart lung machine to prevent air from entering.

2 polyether, low toxicity, commonly used as a pharmaceutical excipient and emulsifier; often used in oral, nasal sprays, eye and ear drops and shampoo in.

3, polyether is an effective wetting agent, can be used for acid Yuzhong textile dyeing, photographic and electroplating, the use of F68 in sugar, because the water permeability increased, can obtain more sugar.

4, polyether is a useful antistatic agent, L44 can provide a lasting protective effect on synthetic fibers.

5, polyether in emulsion paint as dispersing agent. F68 as emulsifier in vinyl acetate emulsion polymerization. L62, L64 can be used as pesticide emulsifier, in metal cutting and grinding as coolant and lubricant. In the rubber vulcanization for lubricants.

6, polyether can be used as a crude oil emulsion breaker, F68, L64 can effectively prevent the formation of hard and dirty oil pipeline, and for the recovery of secondary oil.

7, can be used as papermaking additives polyether, F68 can effectively improve the quality of coated paper.

8, F38 can be used as emulsifier, wetting agent, defoaming agent, demulsifier, dispersing agent, antistatic agent, cleaning agent, viscosity regulator, foam control agent, leveling agent, gelling agent, for the production of agricultural chemicals, cosmetics and medicine; it can also be used for metal processing, washing of pulp and paper industry, textiles processing (textile, dyeing, finishing and soft finishing), water treatment is also used as a rinse aid.

9, P65 is mainly used in textile industry, as a protectant of wool, wool in the carbonization process adding about 0.3%, can reduce the damage of wool, single fiber strength enhanced 10%, reduce the yarn breakage rate of 10%.
