How to improve when the toughness of plastic is poor?

First, the most common method of toughening is to mix the same amount of new materials and recycled materials.

Mixing together with the same amount of new material plus recycled material, this method can drive the toughness of the recycled material because of the good toughness of the raw material. This is also the most common method of toughening, and it also saves costs.

Second, there is a product for toughening plastics in the market: plastic toughening agent (plasticizer)

Adding a toughening agent to the recycled material can make the recycled material toughen.

Toughener It is generally divided into: a particle toughening agent, a liquid toughening agent, and a powder toughening agent.

Three forms of toughening agents. Each brand of toughening agent is added in different amounts and the price is different. A good toughening agent, which makes the toughness of the recycled material the same as the raw material, sometimes better than the toughness of the raw material, and the toughening agent formula of various plastics is different.

Third, in addition to the above two methods of toughening, there is the addition of EVA plastic

EVA: Ethylene-vinyl acetate copolymer is abbreviated as EVA, and the content of vinyl acetate (VA) is generally 5% to 40%. Compared with polyethylene, EVA introduces vinyl acetate monomer into the molecular chain, which reduces high crystallinity, improves flexibility, impact resistance, filler compatibility and heat sealing properties, so it can also be used in recycled materials. Adding EVA can increase the flexibility and impact resistance of the recycled material, thereby increasing the toughness of the plastic.

Tips:

When the plastic is toughened, the number of plastics recovered is different. The toughening effect required by each person is different, and sometimes the amount of toughening agent added is not the same.
