Introduction to PPA application by PPA manufacturers

☆ Automobile components, including fuel, transmission and engine systems, can reduce weight, reduce cost and provide a long service life;

☆ Chip set, socket and cup body welding support;

☆ Chip capacitors, switches and micro speakers, and high-density printed circuit board connectors;

☆ It is used in occasions with high wear resistance requirements, such as non lubricated bearings, seals, bearing isolation rings and reciprocating compressor parts;

☆ Connectors, controllers, sensors, motors and other key electronic components

Density Relative density (water=1) 2.1 Stable

Hazard sign 20 (acid corrosives)

Physicochemical properties Colorless transparent viscous liquid. Easily damp. It can be miscible with water and hydrolyzed to orthophosphoric acid without crystallization. Corrosive.

Uses It can be used as cyclizing agent and acylating agent in organic synthesis. It is also used as a substitute for orthophosphoric acid and an analytical reagent.

Polyethylene plastic drums shall be used for packaging and storage. The net weight of each drum shall be 40/kg. The packaging drums shall be marked with obvious "corrosive articles".

It is a bipolar inorganic acid corrosion product, and the hazard code is GB8.1, 81505. It shall be stored in a cool and ventilated warehouse, and the container must be sealed. It shall not be stored and transported together with alkaline substances, inflammable substances, oxidants, etc. Rain and sunshine shall be prevented during transportation. Handle with care during loading and unloading to prevent the container from cracking and leakage. For the convenience of use, please put it into a warm car or a 50 ° C water bath one day before use.

In case of fire, sand and dry powder fire extinguishers can be used.
