Industry knowledge
High density PVC (Polyvinyl Chloride) sheets are a type of plastic sheet that have a higher density compared to regular PVC sheets. Some of the properties of high density PVC sheets include:
Durability: High density PVC sheets are highly durable and can withstand heavy usage and exposure to extreme temperatures.
Chemical resistance: PVC sheets have a high resistance to chemicals and are able to withstand exposure to acids, bases, and other corrosive substances.
Impact resistance:
High density PVC sheets are impact resistant and can withstand heavy impacts without cracking or breaking.
Weather resistance: PVC sheets are resistant to weathering and can withstand exposure to sunlight, rain, and other environmental conditions without degrading.
Fire resistance: PVC sheets are self-extinguishing and do not support combustion, making them a safer choice for applications that require fire-resistant materials.
Lightweight: PVC sheets are lightweight and easy to handle, making them a popular choice for a variety of applications.
Versatility: High density PVC sheets can be easily fabricated and are available in a variety of colors, textures, and thicknesses, making them suitable for a wide range of applications including signage, point-of-purchase displays, and construction.
PVC sheets for furniture are typically manufactured through a process called extrusion. Here are the general steps involved in the process:
Mixing the PVC resin and other additives: The first step is to mix the PVC resin with other additives such as plasticizers, stabilizers, and pigments. This mixture is then heated in a mixer until it becomes a homogenous mass.
Extrusion: The homogenous mass is then fed into an extruder machine. The extruder is a large cylinder with a screw inside that rotates and pushes the mixture through a die, which is a shaped opening at the end of the cylinder. As the mixture passes through the die, it is cooled by water or air and takes on the shape of the die.
Calendering: After extrusion, the PVC sheet may go through a process called calendering. This involves passing the sheet through a series of rollers that press it into a thinner, more uniform sheet.
Cooling and cutting: Once the sheet has been shaped and calendered, it is cooled and then cut into the desired size and length.
Surface treatment: Finally, the PVC sheet may undergo surface treatment, such as sanding or embossing, to give it the desired texture or pattern.
