UPVC is a 1 amorphous thermoplastic resin made from the polymerization of vinyl chloride monomer, commonly referred to as hard PVC.
1. Material composition and modification
UPVC is mainly composed of polyvinyl chloride (PVC), which is modified by adding stabilizers, plasticizers, fillers and other auxiliary materials.
Compared with ordinary PVC materials, UPVC materials do not contain plasticizers, so they have higher hardness and stability.
2. Features and advantages
Corrosion resistance: UPVC material can resist the erosion of acid, alkali, salt and other chemicals for a long time.
Stability: Due to the addition of stabilizers, the stability of UPVC to light and heat has been improved.
Weather resistance: UPVC material has excellent weather resistance in outdoor environment, and can resist the erosion of natural environment such as ultraviolet light, high temperature and humidity for a long time.
Insulation properties: UPVC material has good insulation properties, can effectively block the conduction of current.
Sound insulation performance: UPVC material has a high density, which can effectively isolate the transmission of noise.
Fireproof performance: UPVC material can effectively prevent the spread of flame.
3. Processing and application
Processing performance: UPVC material can be formed by extrusion, injection molding, blow molding and other processing methods, and can be bonded with other materials, welding and other processing methods.
Applications: UPVC materials are widely used in construction, automotive, electronics, medical and other fields. In the construction field, UPVC is often used to make window frames, door frames, piping systems, wall panels and ceilings.
4. Numbers and Information
Glass transition temperature: The glass transition temperature of UPVC is between 77 and 90 degrees Celsius.
Decomposition temperature: UPVC starts to decompose at about 170 ℃.
Mechanical properties: The tensile strength of UPVC is about 60MPa, and the impact strength is in the range of 5 ~ 10kJ/m².
