40mm Thick Dark Grey PVC Rigid Plastic Sheet

CPVC grey sheet has excellent high temperature resistance (heat deformation temperature 100-120℃) and extreme chemical corrosion resistance (resistance to strong acid/alkali/organic solvents), making it an ideal material for chemical equipment manufacturing. For example, in the lining of concentrated sulfuric acid dilution tanks, CPVC grey sheet can resist sulfuric acid erosion with a concentration of less than 98% (service life > 10 years), avoiding the risk of leakage caused by corrosion of metal equipment; in the laboratory's high-temperature reactor bracket, its short-term resistance to 150℃ high temperature (ordinary PVC can only withstand 80℃) ensures that the bracket does not deform in a high temperature environment (ensuring the stability of the reactor); in the acid-base wastewater treatment pipeline system of the electroplating plant, the ability of CPVC grey sheet to resist alternating strong acid/alkali erosion (no swelling or cracking) significantly extends the life of the pipeline (> 8 years).

 

The characteristics of high tensile strength (50-60MPa) and oxygen index ≥ 45 make CPVC sheet outstanding in the fields of electrical insulation and architectural decoration. For example, in the partition design of high-voltage switchgear, the excellent insulation (dielectric strength 30-35kV/mm) and flame retardancy (UL94 V-0 standard) of CPVC grey sheets can effectively prevent fires caused by arc sparks (improve the electrical safety level); in the fire-proof air duct system of high-rise buildings, its low smoke and low toxicity characteristics (smoke toxicity index during combustion <10, ordinary PVC>50) buy precious time for personnel evacuation (in compliance with GB 8624 B1 fire protection standard); in the cable tray of the data center computer room, the high strength (bearing capacity>200kg/m²) and flame retardancy of CPVC grey sheet ensure the long-term safe operation of the cable (service life>15 years).

 

Chlorination modification gives CPVC grey board the ability to resist chloride ion penetration (no significant performance degradation after immersion in chloride ion solution for 10 years), combined with weather resistance (outdoor service life>10 years), making it the preferred material for marine engineering and outdoor building decoration. For example, in the pipeline system of desalination equipment in coastal areas, the ability of CPVC grey board to resist high salt spray environment erosion (no pitting or cracking) significantly reduces maintenance costs (inspection every 5 years, ordinary PVC needs to be replaced every year); in the cable protection cover of the cross-sea bridge, its UV resistance and chloride ion corrosion resistance synergistically (service life> 15 years) protect the cable from marine climate damage; in the production of the base of outdoor sculptures, the weather resistance (resistance to ultraviolet rays and wind and rain erosion) and impact resistance (resistance to wind and sand impact) of CPVC grey board ensure that the sculpture is stable and beautiful for a long time.

 

CPVC grey sheet can be processed by a variety of processes such as hot bending and CNC engraving, and has a low thermal expansion coefficient (about 6-8×10⁻⁵/℃), which is suitable for manufacturing high-precision parts. For example, in the production of special-shaped pipe connectors for chemical equipment, the CNC engraving process can achieve a dimensional accuracy of ±0.1mm (the processing accuracy of ordinary PVC is only ±0.3mm), thereby improving the sealing of the equipment; in the customized experimental table tops in the laboratory, the hot bending process can produce curved edges (improving operational safety) without significant deformation during long-term use (tolerance <0.2mm/year); in the production of special-shaped ceiling panels for architectural decoration, the low thermal expansion coefficient of CPVC grey sheet (15%-20% lower than PVC) ensures uniform splicing gaps (no cracking caused by thermal expansion and contraction).
