UPVC profile, also known as hard PVC, is an amorphous thermoplastic resin made by the polymerization of vinyl chloride monomer, and a certain amount of additives such as stabilizers, lubricants, fillers, etc.
Physical properties:
UPVC has high melt viscosity and poor fluidity, so the molding temperature range is narrow, and it is the 1 material that is relatively difficult to mold.
In the treatment of UPVC, it is usually necessary to carry out modified granulation in order to improve its processing properties.
UPVC particles absorb less than 0.02 percent of water after 24 hours at room temperature, so drying is usually not required.
Mechanical properties:
UPVC profile has good water pressure resistance, impact resistance, tensile strength, can withstand high pressure.
High mechanical strength, such as water supply UPVC pipe at room temperature can withstand 110 atmospheric pressure for 1 hour without breaking.
Chemical properties:
UPVC profile acid and alkali resistance, corrosion resistance, no rust, no scaling, help to protect water quality, to avoid secondary pollution of water quality.
The unique green environmental protection lead-free formula system replaces the traditional compound lead salt formula system, which will not damage the water quality and affect human health.
Processing and installation:
The molding of UPVC requires special plasticizing parts and temperature control systems to cope with its high melt viscosity and easy decomposition characteristics.
The density of UPVC pipe is the 1/5 of general cast iron, and it is easy to carry, load and unload, and the installation and construction are simple and quick.
Application areas:
UPVC pipes are widely used in water piping engineering, water-saving irrigation piping engineering, construction piping engineering and other fields.
Due to its excellent insulation capacity, UPVC pipe can also be used as a post and telecommunications cable conduit.
In chemical plants, UPVC pipes are commonly used as infusion pipes because of their acid and alkali resistance and corrosion resistance.
Other Features:
UPVC pipe is light in texture and good in water tightness. After 15 minutes of adhesive bonding, the bonding strength can reach more than 12.5/C.
The use of temperature range to room temperature for the best, low temperature brittleness increases, high temperature tensile strength decreased.
