The difference
1. Different raw materials
PP pipe is made of polypropylene. PE raw material is polyethylene. PVC raw material for polyvinyl chloride.
2. Different degrees of bending
The PP tube should not be bent when used. PVC is not bendable, PPR can be bendable 20 times the pipe diameter.
PE tube can bend 180 degrees. PE pipe has its flexibility, it can be bent and then straight for use. During production, it can be bent and rolled into hundreds of meters of coil pipe. This is a normal bending situation.
3. Different uses
PP pipe general purpose pressure water delivery, and drinking water delivery.
PE is generally large diameter, used for cold water supply pipe, because there is no polarity, so it has low dielectric loss, high dielectric strength of excellent electrical performance, can do frequency modulation insulation material, corona resistant plastic, and can do high voltage insulation material.
Precautions for purchasing pp material products are as follows
When purchasing pp material products, we must understand the raw materials of the product. Many regular manufacturers in the production of pp material products, generally use pure pp material for production, but also some pp material products are not produced using pure pp material, because some manufacturers in order to save production costs, will add some other materials in the production. Under normal circumstances, there is no harm to human health, and it is in the food grade pp material products are the best.
When purchasing pp material products, be sure to observe the appearance of the product in detail. In general, the appearance of high-quality pp material products is generally transparent or translucent, and generally will be more shiny, but also more beautiful, in addition, there will be no burr phenomenon.
