When the recycled material, water mouth material and add filler processing finished products to reduce costs, in the high cost of raw materials today is the path of each company must be, but its finished products are fragile and easy to break, toughness is not good, has been the plastic industry is more headache!
So how to solve this problem?
First, the most common method is toughening: using an equal proportion of new material plus recycled material mixed together
With equal proportions of new materials plus recycled materials mixed together, this method because the toughness of raw materials is good, it can drive the toughness of recycled materials. This is also one of the most common methods of toughening. And also save cost.
Second, the market has launched a product for plastic toughening: plastic toughening agent (plasticizer)
Toughening agents are added to recycled materials to toughen them.
Toughening agent it is generally divided into: granular toughening agent, liquid toughening agent, powder toughening agent.
There are three types of toughening agents. Each brand of toughening agent has a different amount of additives. The price is also different. A good toughening agent can make the recycled material as tough as the raw material, sometimes even tougher than the raw material. Various plastic toughening agent formulations are not the same.
Third, in addition to the above two toughening methods, there is the addition of EVA plastic
EVA: ethylene - vinyl acetate copolymer referred to as EVA, general vinyl acetate (VA) content in 5% to 40%. Compared with polyethylene, EVA due to the introduction of vinyl acetate monomer in the molecular chain, thereby reducing the high crystallinity, improving flexibility, impact resistance, filler compatibility and heat sealing properties, so you can also add EVA in the recycled material it can make recycled material to improve flexibility, impact resistance. This increases the toughness of the plastic.
When toughening plastics, the number of times the plastic is recycled varies. And each person requires different toughening effect, sometimes the amount of added toughening agent is also different.
