Polyvinyl chloride has the advantages of flame retardancy (flame retardancy value of 40 or more), high resistance to chemicals (resistance to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid, and 20% sodium hydroxide), good mechanical strength, and good electrical insulation.
Polyvinyl chloride is less stable to light and heat. The softening point is 80℃, and it starts to decompose at 130℃. In the case of not heating stabilizers, polyvinyl chloride was 100 ℃ when the decomposition began, 130 ℃ above the faster decomposition. Heat decomposition releases hydrogen chloride gas (hydrogen chloride gas is a toxic gas) to make it change color from white → light yellow → red → brown → black. Ultraviolet rays and oxygen in the sunlight will cause PVC photo-oxidative decomposition, decreasing the flexibility of PVC and making it brittle. This is why some PVC plastics become yellow and brittle after a long time.
It has stable physicochemical properties, insoluble in water, alcohol, gasoline, low gas, and water vapor leakage; it is resistant to any concentration of hydrochloric acid, sulfuric acid up to 90%, 50-60% nitric acid, and caustic soda solution up to 20% at room temperature, and it has a certain degree of chemical corrosion resistance; it is pretty stable to salts, but it can be dissolved in organic solvents such as ether, ketone, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbons, etc. It is a yellowish semi-transparent PVC. Polyvinyl chloride is slightly yellow, translucent, and glossy. Transparency is better than polyethylene and polypropylene and worse than polystyrene, with different additives divided into soft and hard polyvinyl chloride. Soft products are smooth and rigid and have a sticky feel. Complex products are higher than the hardness of low-density polyethylene but lower than polypropylene; the bending place will have a whitening phenomenon. Stable; not easily eroded by acids and alkalis; more heat-resistant.
PVC set screws are a kind of hard plastic screws with the advantages of lightweight and chemical resistance. It suits some environments requiring chemical resistance, such as acid and alkali.
PVC screws: The strength of PVC screws is low, around 200MPa, suitable for some light load occasions.
