How to solve the problem of poor toughness of waterproof vents

1. Now the most common is the toughening method: mix the same proportion of new material and recycled material in the same

Mix the same proportion of new materials and recycled materials together. This method can drive the resistance of recycled materials because of the good resistance of raw materials. This is also one of the most common toughening methods. And also save money.

2. A product for toughening waterproof vents has been launched in the market: toughening agent is added to the recycled material, which can make the recycled material play a toughening role. Toughening agent It is generally divided into: particle toughening agent, liquid toughening agent, powder toughening agent. Each brand of toughening agent they add is different. The price is also different. A good toughening agent, it can make the resistance of the recycled material the same as that of the raw material, sometimes better than that of the raw material.

3. In addition to the above two toughening methods, there is also the addition of EVA

EVA: Ethylene Vinyl Acetate Copolymer is abbreviated as EVA, - generally, the content of Zene acetate (VA) is 5% to 40%. Compared with poly-Zene, EVA can also be used in recycled materials because of the introduction of vinyl acetate monomer into the molecular chain, which reduces the high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. Adding EVA can improve the flexibility and impact resistance of recycled materials. Then increase the resistance of waterproof vents.
