Classification of PP Pipes
PP-H (High Molecular Weight Polypropylene Pipe)：
Raw MaterialsAll made from polypropylene monomer, with a uniform and regular molecular arrangement.
FeaturesHigh strength, good chemical and high-temperature resistance, but poor low-temperature impact resistance.
Applicable ScenariosSuitable for the transport of high-temperature liquids and chemicals, such as in chemical plants and industrial pipelines.
PP-B (Block Copolymer Polypropylene Pipe)：
Raw MaterialsMade by copolymerization of propylene monomer and ethylene monomer.
FeaturesSofter and more flexible than PP-H pipes, with improved low-temperature impact resistance.
Applicable Scenarios主要用于 cold and warm water conveyance, suitable for building potable water and drainage systems.
PP-R (Random Copolymer Polypropylene Pipe)：
Raw MaterialsEthylene monomers are irregularly distributed within the molecular chain, forming a uniform copolymer.
FeaturesThe crystallinity falls between PP-H and PP-B, offering a balance of rigidity, good flexibility, and low-temperature resistance.
Applicable ScenariosCommonly used for cold and hot water pipes in residential and commercial buildings, ground heating systems, and drinking water supply.
