PPH sheet is a modified high performance polypropylene material, high molecular weight, low melt flow rate homopolymer polypropylene, it is a PP modified material, after β-modification with fine crystalline structure.
Properties of PPH sheet
Physical Properties
-
Light weight
– The specific gravity of PPH sheet is only one-seventh of that of metal pipe, which is light, light weight, easy to carry and install, and low density, easy to carry and install.
-
Aesthetic appearance
– The product has smooth inner and outer walls, low fluid resistance, soft color and beautiful shape.
-
Uniform thickness, smooth and flat
– Processed through extrusion, calendaring, cooling, cutting and other processes, it is characterized by uniform thickness, smoothness and flatness.
Performance Characteristics
-
Corrosion resistance, no scaling
– Can be avoided due to pipe corrosion caused by the water basin, bathtub yellow rust stains of worry, can be exempted from pipe corrosion scaling caused by clogging, most of the acids, alkalis and solvents have good corrosion resistance, resistance to most of the acids, alkalis, salts and other chemicals, applicable to corrosive environments, such as chemical plants, laboratories, etc., in all polypropylene materials, experiments have proved that PPH material has the strongest chemical resistance properties. Among all polypropylene materials, experiments have proved that PPH material has the strongest chemical resistance.
-
High temperature and pressure resistance
– Pipeline water temperature up to 95 ° C, PPH plastic sheet can maintain stable performance in high-temperature environments, can withstand temperatures up to 100 ° C, the applicable temperature range from – 20 ° C to +100 ° C, in high-temperature environments can also maintain stability, heat-resistant performance can reach more than 100 ° C, for high-temperature working environments.
-
Thermal insulation and energy saving
– Thermal conductivity of only one-hundredth of the metal pipe, used for hot water pipe insulation and energy saving effect is excellent.
-
Good mechanical properties
– High strength and rigidity, can withstand a certain load and impact, in the process of use is not easy to break or deformation, to maintain a stable shape, but also has a good impact resistance and tensile properties.
-
Strong recovery elasticity
– Can be compressed by 50%, high strength, durable, can not be replaced by rubber and other materials and so on.
- Pressure and shock: Resistance, impact resistance, oil resistance, acid and alkali resistance, excellent abrasion resistance.
– Our PPH series elastomers have superior tensile strength, tear resistance, high elasticity, high pressure load resistance, abrasion resistance and other characteristics.
-
Good electrical insulation
– Can be used for electrical insulation materials, has good electrical insulation properties, not easy to conduct electricity, can effectively block the current and electromagnetic waves.
-
Low water absorption
– PPH – H sheet has low water absorption, its surface is not easy to adsorb moisture, can maintain stability in a humid environment.
High Performance and Easy Welding
– High performance and easy to weld, PPH material has the highest pressure resistance among all system polypropylene materials, providing longer service life and greater system safety.
Excellent Impact Resistance at Low Temperatures
– Excellent impact strength even at low temperatures. Compared with conventional engineering plastics, PPH materials have significant low-temperature impact strength.
Production of PPH sheet
Production process
Extruded, calendered, cooled and cut.
