What material is toughened with PP? What to add to increase liquidity?

PP plus PP toughener material toughening.

PP increases liquidity:

1. Add pp wax, you can also add polyethylene wax.

Small impact. 2. Add silicone.

Powder, this effect is good, but expensive. There is little impact on material properties.

3. You can also add PP with high fluidity, that is, PP with high melt index, which has some effects.

PP Toughener:

Yupu bifunctionalized toughened compatibilizer is a kind of impact performance reinforcing agent for modified products based on multiple blending system and using bidirectional grafting reaction technology as the process route for different modified products, which overcomes the limitations of the application of the compatibilizer produced by the traditional single base material and single grafting process, and takes into account the other physical properties of the modified product under the premise of toughening and capacitizing, and the comprehensive performance is very good. Due to the high two-way grafting effect on the main chain of this type of product, the binding force between organic and inorganic in the two-phase and filling modification of co-mixed gold is greatly enhanced, and can be used as an interface modifier for glass fiber and mineral filling materials, and can also be used as a compatibilizer between the two phases of co-mixed gold. At the same time, due to the introduction of toughening materials, the toughness of the blended materials is multiplied under the synergistic effect of two-way effects.

PP increases liquidity:

One of the simple and effective methods is to add the right amount of polypropylene plastic to the PP resin before processing molding.

Flow enhancer, through special chemical and physical action, can greatly improve the melt flow index of polypropylene plastics under the condition of small amount of use.

Increase the processing fluidity of polypropylene and improve the surface gloss of polypropylene products.

It is suitable for various molding processes of polypropylene, such as blow molding.

Injection molding, extrusion, coating, rotational molding and other products are easy to use, safe and environmentally friendly, and are produced by domestic Ruida Chemical, Maanshan Keli Chemical Technology and other enterprises. There are also similar products abroad. There are other plastic flow enhancers such as polyethylene flow enhancer, pcabs flow enhancer, etc.

Flat wire fracture and brittleness are different concepts, if the product is brittle, it must be the reason for the toughening agent or rigid particle toughening break: 1. The impurities in the recycled material --- know best if the professional does the recycled material, and the strip will not stop breaking when granulating. Don't make calcium carbonate too coarse.

2. If the 34% recycled material is polyethylene, it is also necessary to consider the compatibility with PP. 3. Don't add too high a temperature to the fluidity. PP degradation is more severe, and the product is brittle.

4. The production is slowly starting to break off, and the net is being changed. View the original post

PP material. The addition of ethylene propylene rubber can increase toughness and hardness.

Ethylene propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers, and there are two ethylene propylene diene monomers and ethylene propylene diene monomers according to the different components of the monomers in the molecular chain.

The former is a copolymer of ethylene and propylene, which is expressed as EPM, and the latter is a copolymer of ethylene, propylene and a small amount of non-conjugated diolefin third monomer, which is expressed as EPDM.

Collectively known as ethylene propylene rubber (EPDM), it is widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals, lubricating oil additives and other products, which can increase toughness and hardness.

Generally speaking, PP should increase toughness and strength, and the way of adding glass fiber can be used. For example, winding reinforced PP pipes are used in a similar way, and the toughness and hardness of pipe fittings can be enhanced in this way.

Hello, about your question, I think PP material plus EPDM rubber can increase toughness and hardness. Ethylene propylene rubber is a synthetic rubber with ethylene and propylene as the main monomer, according to the different monomer compositions in the molecular chain, there are two types of ethylene propylene rubber and ethylene propylene monomer, the former is a copolymer of ethylene and propylene, expressed in EPM, and the latter is a copolymer of ethylene, propylene and a small amount of non-conjugated diene third monomer, expressed in EPDM.

The two are collectively known as ethylene propylene rubber, which are widely used in automotive parts, waterproof materials for construction, wire and cable grip sheaths, heat-resistant hoses, tapes, automotive seals, lubricating and date oil additives and other products, which can increase toughness and hardness.

The average molecular weight of ethylene propylene rubber is 200,000-400,000, the average molecular weight is 50,000-150,000, and the average molecular weight of viscosity is 100,000-300,000. The amount of weight-weighted diggers is closely related to Mooney viscosity. The Mooney viscosity value of ethylene propylene rubber [ml(1+4)100] is 25-90, and there are many varieties of Mooney value of 105-110.

With the increase of Mooney value, the filling capacity also increases, but the processing performance deteriorates. The tensile strength and resilience of the vulcanized ethylene propylene rubber have been improved. The molecular weight distribution index of ethylene propylene rubber is generally 3-5, mostly around 3. EPDM with wide molecular weight distribution has good mixability and calendering properties of open mill defects.

Summary. Hello pro generally pp plastic is added in the following ways to increase toughness and elasticity:

1 Ethylene propylene diene monomer (EPR) modified PP

In order to improve the impact performance of PP, people have long used rubber and PP blending. Due to its good compatibility with PP, EPR has become the most commonly used rubber variety in toughened PP. Blending EPR with PP can improve the impact strength and low-temperature brittleness of PP.

When the EPR content is 20%, the notched impact strength of PP EPR blend is 10 times higher than that of pure PP, and the embrittlement temperature is as much as 4 times lower than that of pure PP.

What to add to PP plastic to increase toughness and elasticity.

Hello pro Generally, there are several ways to increase the toughness and elasticity of PP plastics: 1 Ethylene propylene diene monomer (EPR) modified PP In order to improve the impact performance of PP, people have long used rubber and PP blending. Due to its good compatibility with PP, EPR has become the most commonly used rubber variety in toughened PP.

Blending EPR with PP can improve the impact strength and low-temperature brittleness of PP. When the EPR content is 20%, the notched impact strength of PP EPR blend is 10 times higher than that of pure PP, and the embrittlement temperature is as much as 4 times lower than that of pure PP.

2 The toughening of PP by EPDM modified by EPDM is similar to that of EPR, and the impact strength of the system is greatly improved with the increase of EPDM content. When the EPDM content is 20%, the notched impact strength of PP EPDM blend is about 4 times higher than that of pure PP, and the low temperature resistance is improved.

The 3 pp br blend system butadiene rubber (br) has excellent characteristics such as high elasticity, good low temperature performance (glass transition temperature is about -110), abrasion resistance, flex resistance, etc. Moreover, its tolerance parameters are similar to PP, and practice has proved that their compatibility is good and the toughening effect is obvious. The polypropylene powder with the domestic volume index and the butadiene rubber with a domestic Mooney viscosity of 44 are pressed at 100; 15 (mass ratio) blending, the impact strength of the obtained PP BR blend at room temperature is 6 times higher than that of pure PP, and the embrittlement temperature is reduced by 4 times.

At the same time, the extrusion expansion ratio of the blend is smaller than that of PP, PP LDPE, PP EVA, etc., and the dimensional stability after molding is better.
