What acids and plastics can react with

Concentrated sulfuric acid, it is strongly corrosive.

Bromine water. Can be added with plastic.

This is related to the type of plastic, and it is also related to the type of acid, so it cannot be generalized.

The concept of plastic and acid is too broad, what kind of plastic do you see, ester plastics are generally not resistant to acid and alkali, easy to chemical reactions, general plastics and most engineering plastics have better acid and alkali resistance, but you have to look at the strength of acid and alkali, as well as the length of contact time, plastic is still not suitable for long-term contact with strong acids and alkalis.

Depending on what kind of plastic it is, most of it doesn't react at all. PC material is not resistant to strong acids and alkalis, and there will be chemical reactions.

Not reacting... How did you come up with it?

Liaojing Technology will answer for you: the performance and use of commonly used plastic varieties

1 Polyethylene: Commonly used polyethylene can be divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact properties and film-forming.

LDPE and LLDPE are mainly used for packaging films, agricultural films, plastic modification, etc., while HDPE is widely used, such as films, pipes, injection daily necessities and other fields.

2 Polypropylene: relatively speaking, polypropylene has more varieties, and its uses are more complex, with a wide range of fields, including homopolymer polypropylene (homopp), block copolymer polypropylene (COPP) and random copolymer polypropylene (RAPP), according to different uses, homopolymer is mainly used in wire drawing, fiber, injection, BOPP film and other fields, copolymer polypropylene is mainly used in household appliances injection parts, modified raw materials, daily injection products, pipes, etc., random polypropylene is mainly used in transparent products, High-performance products, high-performance pipes, etc.

3 Polyvinyl chloride: Due to its low cost and self-flame retardant characteristics, the product is widely used in the construction field, especially sewer pipes, plastic steel doors and windows, plates, artificial leather, etc.

4 Polystyrene: As a transparent raw material, it has a wide range of uses in the case of transparent needs, such as car lamp covers, daily transparent parts, transparent cups, cans, etc.

5 ABS: It is a widely used engineering plastic, with outstanding physical, mechanical and thermal properties, widely used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as washing machines, air conditioners, refrigerators, fans, etc., the amount is very large, and in terms of plastic modification, it is also widely used.

Polyethylene plastics can be dissolved in acetone solutions.

Plastic is a polymer material, the backbone is C, so it is resistant to strong acids and alkalis, but some unsaturated plastics have weaker oxidation resistance. Therefore, saturated plastics such as polyethylene are generally used to contain nitric acid.

No, I used nitric acid in a plastic bottle, and nothing happened.

Many, the simplest way to burn plastic is to oxidize with oxygen.
