What is the difference between PVC and rigid PVC?
Generally speaking, rigid PVC compounds are usually denser and harder, which makes them strong and durable. Rigid PVC could be stronger and more durable, while flexible PVC can be made to be resistant to chemical and liquid damage.
What is the use of Unplasticised PVC?
As additive-free PVC begins to decompose before it melts, it can only be melt processed by the use of copolymers or the addition of stabilizers (or by the addition of plasticizers which gives rise to products of different properties)….Typical Properties.

What does rigid PVC mean?
polyvinyl chloride
Rigid PVC (polyvinyl chloride) is a strong, stiff, low cost plastic material that is easy to fabricate and easy to bond using adhesives or solvents. PVC is also easy to weld using thermoplastic welding equipment. It is frequently used in the construction of tanks, valves, and piping systems.
Can PVC be injection molded?
Injection Molding: Polyvinyl Chloride can be injected just like other plastics, but chlorine in the material complicates the process. This is because melted PVC can give off a corrosive, toxic gas.
What is the difference between uPVC and SWR pipes?
The SWR stands for Soil, Waste and Rain and uPVC stands for unplasticized phthalates. The significant difference between these channels is essentially the distinction in material and their properties. UPVC and SWR are non-metallic pipes. They are produced using thermoplastic materials.
What is the difference between uPVC and mPVC?
mPVC is more ductile and has a higher toughness than uPVC, and therefore can get away with a lower safety factor than uPVC. uPVC isn’t softened by plasticisers and therefore is more durable compared to mPVC. uPVC’s thicker wall also makes fabrication more precise.
Which PVC is the most rigid?
Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications. For jobs that require a higher pressurization though, schedule 80 pipe is better suited. Most PVC pipe and fittings have a maximum pressure rating listed so you know what it can handle.
Is PVC easy to mold?
Rigid PVCs are the most interesting injection moldable members of this family of materials. The first PVCs were rigid but their brittleness limited their use. Their high viscosity and heat sensitivity made them difficult to injection mold.
What is Unplasticised PVC?
Unplasticised Polyvinyl Chloride – Unplasticised PVC – UPVC. It is an amorphous commodity thermoplastic that can be colorless and transparent but is much more commonly pigmented. It is strong, stiff, and inherently flame retardant with relatively good chemical resistance (solvents are its weak area, particularly stress cracking therein).
Is UPVC a rigid plastic?
Unplasticized (Rigid) Polyvinyl Chloride (uPVC, PVC-U) UPVC is a thermoplastic, further classified as a polyvinyl plastic. It has a moderately low heat capacity among thermoplastics. In addition, it has a moderately high ductility and a moderately low tensile strength.
What is the difference between regular PVC and rigid PVC?
Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers. If no plasticizers are added, it is known as uPVC (unplasticized polyvinyl chloride), rigid PVC, or vinyl siding in the U.S.
What is the difference between PVC and UPVC siding?
PVC vs. uPVC. Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers. If no plasticizers are added, it is known as uPVC (unplasticized polyvinyl chloride), rigid PVC, or vinyl siding in the U.S.
