When recycled materials, nozzle materials and added fillers are processed to reduce costs, today's high raw material costs are the path of every company, but the finished products are fragile and easy to break, and the toughness is not good. A headache!
So how to solve this problem?
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. The price is different. A good toughening agent, which makes the toughness of the recycled material the same as the raw material, and sometimes better than the toughness of the raw material. Different plastics have different toughening formulations.
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 makes the recycled material more flexible and impact resistant. 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.
