PP characteristics, what are the ways to toughen PP?

Hello everyone, I'm Oda who does plastic trade. This is the only headline number I have seen and known in the plastics industry

Talent is shallow, industry knowledge is wrong, imperfect places welcome correction.

Although pp has the advantages of environmental protection and non-toxicity, light weight, good folding resistance, etc., the main disadvantage of pp is poor low temperature resistance. General homopolymer pp material, the temperature is lower than -10 degrees, the material becomes extremely brittle. The copolymer impact grade pp can withstand low temperatures -20 degrees.

How to make polypropylene (pp) plastic products resistant to low temperatures, usually pp raw materials at low temperatures show embrittlement, the product is easy to crack, then how to improve this problem, so that it can be widely used in various fields.

Toughening and hardiness method one: blended with polyethylene (pe), pe's low temperature embrittlement temperature can reach -70 degrees, adding an appropriate amount of PE can change the low temperature resistance of pp, but excessive pe added will affect the hardness of pp products.

Toughening and hardiness method two: polyolefin (poe) toughening, poe has the general characteristics of thermoplastic elastomer, small density, heat resistance, excellent cold resistance, wide range of temperature, is to change pp low temperature resistance is ideal material, usually add the appropriate amount can make polypropylene pp reach -20 degrees or more, the use of poe hardiness grade to toughen PP, not only change the original pp more low temperature resistance, impact determination will also increase. 

Toughening pp is also very common, in pp to add a special pp toughening agent such as poe, such a material has both good rigidity, and good low temperature toughness, its toughness effect is good, in the toughness modification, blend modification due to low cost, fast effect, has become a wide range of toughening methods. There is also a key reagent here - nucleating agent, using microemulsion as a nucleating agent carrier to add benzoic acid to pp, which can make the nucleation agent well distributed in polypropylene, so that polypropylene has a better bending modulus and better toughness.

Oda is the agent of Korean sk, but also do sk of poe Oh, there is a need, Oda can also give you a quote, you compare it.
