Study Notes

PVC Overview

PVC is a versatile material, easy to work with
Solid PVC and foamed PVC are two types
Each type has distinct properties

Types of PVC

Solid PVC: Solid sheet, impact-resistant, good machinability
Foamed PVC: Solid top layers with foamed core, not impact-resistant

Other Names for PVC

Unplasticized PVC (uPVC): Solid, strong PVC
Plasticized PVC (pPVC): Flexible, soft PVC
Different categories exist based on properties, production methods, and use

Chemical Properties of PVC

Chemical stability: Resistant to many chemicals (acids, alkalis, salts)
Flame resistance: Hard to ignite, flame retardant
Durability: Withstands harsh conditions, moisture, higher temperatures
Insulating properties: Good electrical insulator
Hygenic: Bacteria and similar items do not adhere well

Density

PVC density ranges from 1.38-1.59 g/cm³

Manufacturing Process of PVC

Polymerization: Vinyl chloride monomer (VCM) polymerizes into polyvinyl chloride (PVC) resin
Mixing: PVC resin mixes with additives (stabilisers, lubricants, pigments) for improved properties
Extrusion: Melted mixture pushed through a die to form a continuous profile
Cooling: Solidifies the profile, maintaining the desired shape

Applications of PVC

Construction: Pipe systems, profiles, flooring, cable insulation, roofing
Healthcare: Medical pipes, blood bags, infusion bags
Automotive: Interior/exterior cladding, electrical insulation, hoses, fuel lines, coolant hoses

Available Colours and Thicknesses

Solid and foamed PVC come in various colours and thicknesses
Foamed PVC has a variety of special colours

Processing Possibilities of PVC

Solid PVC: Cutting, drilling, welding, printing, milling
Foamed PVC: Cutting, printing, milling
Depending on application, there are several mounting methods

Assembling PVC

Solid PVC - mounted with screws, nails, glue, brackets/clips
Foamed PVC - more vulnerable. Can be attached with glue or mounting stands for support

Properties of PVC

Solid PVC Advantages: Chemical resistance, strong, durable, easy to maintain, moisture resistant, mould resistant, easy to process, lifespan of 30+ years
Solid PVC Disadvantages: (Not explicitly mentioned, but implied)
Foamed PVC Advantages: Light weight, Chemical resistant, High insulation value, Aesthetic, Easy care, Moisture resistant, easy to work with, lifespan of 30+ years
Foamed PVC Disadvantages: Less strong than solid PVC, not suitable for extreme weather conditions

How to maintain PVC

Clean with mild soapy water and a soft cloth.
