what is rigid PVC?,
rigid PVC extrusion, uPVC,

Rigid PVC (also known as uPVC) is the third most widely produced polymer. In terms of plastic extrusions, PVC is the most frequently extruded rigid plastic. It is low cost, has recyclable properties and is versatile for both indoor and outdoor use. This makes rigid PVC extrusions a popular choice for a wide range of applications. uPVC stands for unplasticised PVC and the material is characterised by its durability and strength. It’s also an extremely adaptable plastic, great for many applications
Rigid PVC properties

PVC is a hard polymer that can be further enhanced using impact modifiers. Rigid PVC extrusions have strong chemical resilience. This means rigid PVC tubing can be easily welded, glued and fused to itself – ideal for joints in pipes. Its resistance to corrosion makes extruded rigid PVC profiles, sections and trims suitable for outdoor environments. PVC also has good insulation properties for low voltage electrical uses. Thanks to its multiple benefits, rigid PVC extrusions and rigid PVC tubing has been used with success in both indoor and outdoor locations.

Rigid PVC extrusions in use
Rigid PVC is widely used in construction for water and waste pipes, conservatories, gutters, cladding, wall and door protection and window frames due to its excellent thermal properties and stability. In transport applications uPVC is used externally for vehicle bodies, caravans and boating, and internally for creating pleasing aesthetics, since it is available in many colours and surface finishes. In the retail sector point of sale displays, storage racks, ticket strips and poster grippers are all produced from extruded rigid PVC.

Features thermo plasticity, being insoluble into water, gasoline and alcohol, swelled or dissolved into ether, ketone, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbon, high resistance to corrosion, and good dielectric property.

Application

PVC Resin SG-3 Application to :

1. PVC profile
Profiles are the field of PVC consumption in domestic country, about 25% of total PVC consumption, mainly for making doors and windows and energy-saving materials, and their application is still large and growth.

2. PVC pipe
PVC pipes are the 2nd largest consumption industry,The consumption is 20% of total production capacity in Domestic of China, the PVC Pipe .

3. PVC film
The PVC film filed is the 3rd big quantity consumption , it is about 10% of total production capacity.
