What Is Polypropylene Random PPR

Polypropylene random are produced by the addition of ethylene to propylene during the polymerization process. The methyl groups on the main chain of the PPR three-dimensional structure are randomly arranged on both sides of the molecular chain. It has ethylene units, typically up to 6% by mass, randomly incorporated into the polypropylene chain. The random incorporation of ethylene in the homopolymer matrix during polymerization results in PP resins with excellent clarity and gloss, making them suitable for applications requiring transparency and for products requiring excellent appearance.

Know More About PP Random

It has excellent comprehensive properties, including high strength, heat resistance, dimensional stability, excellent flexibility at low temperatures, high transparency and high gloss.

Excellent aesthetics and optical performance.

High impact properties at room temperature along with good thermal stability and chemical resistance properties.

Characteristics of lower melt temperature and ease flow can lead to opportunities for process optimization.

Since random polypropylene is amorphous, its solubility is better than that of isotactic polypropylene. Atactic polypropylene is easily soluble in heptane, hexane, pentane and other linear alkanes, soluble in benzene and toluene and other aromatic hydrocarbons, slightly soluble in carbon tetrachloride, chloroform and other chlorinated hydrocarbons and organic solvents, but insoluble in water , ethanol, acetone and other low molecular alcohols and ketones.

Compared with isotactic polypropylene, PPR has an irregular molecular arrangement and a lower molecular weight. It is inferior to isotactic polypropylene in terms of rigidity, heat resistance and chemical corrosion resistance. However, random PP copolymer is better than isotactic polypropylene in terms of flexibility, low temperature resistance, wettability, solubility and processing fluidity.

Random PP copolymers are less stiff than PP homopolymers but have higher impact properties at room temperature.

Random PP has poor mechanical and thermal properties due to its small molecular weight, irregular structure and small cohesion.

Random polypropylene has good compatibility with polyethylene, polypropylene, polybutylene, synthetic rubber, paraffin, asphalt, etc., So it can be blended with them to expand its applications.    

Random PP copolymer has been widely used in chemical industry, light industry, textile, medicine, transportation, plastics, agriculture, etc.

High-definition and high-transparency packaging can be produced from random pp through injection molding, blow molding and thermoforming processes.

PP random copolymer combines the strength and chemical resistance of polypropylene PP with enhanced clarity and impact resistance, making it the first choice for applications that require both performance and aesthetics.

From clear containers to medical equipment, its versatility makes it a valuable asset in a variety of industries.   

Random copolymer polypropylene is copolymerized by heating, pressurizing and catalyzing propylene monomer and a small amount of ethylene monomer. Ethylene monomers are distributed randomly along the propylene chain. The random addition of ethylene reduces the crystallinity and melting point of the polymer, while improving the material’s impact performance, long-term hydrostatic pressure performance, and long-term thermal oxygen aging resistance, making it more suitable for pipe processing and molding. The molecular chain structure and ethylene monomer content of PPR directly affect the long-term thermal stability and mechanical properties of the material. The more randomly the ethylene monomer is distributed in the propylene molecular chain, the more significant the changes in polypropylene properties will be.
