Everything You Need to Know About Type 1 PVC Along With Its Fabrication Methods



Introduction:

Type 1 PVC is a kind of thermoplastic product with widespread applications across diverse industries. Unlike most other plastics, PVC is relatively inexpensive to produce and highly workable, allowing it the capability to be used as anything from pipe making to electrical insulations and exterior coatings.

Manufacture of Type 1 PVC:

Type 1 PVC is usually made using UV stabilization method, which is a method of thermoforming plastic. Thermoforming involves applying heat and pressure of varying kinds on plastic sheets to modify them into desired shape and design. UV stabilization process uses UV rays to provide heat which helps in its uniform distribution, followed by cooling. They require temperatures in the range of 266 degrees Fahrenheit and 338 degrees Fahrenheit to become workable enough to mould them into shape.

However, UV stabilization method forms just a part of the fabrication process. Other parts of the fabrication process are:

Machining: 
This process involves using low-speed rotors to shape plastic sheets into desired dimensions and chipping off unused parts from the finished product. Low speeds are preferred to have more control over chipping and to prevent severed chips from flying around everywhere.

Welding: 
Hot air welding is often used to join two or more type 1 PVC parts, either in its raw form or finished form as necessary. However, welding is a form of destructive joining, so it is preferable to use only for joining large parts where welds won’t be very visible.

Bonding:
In cases where welding cannot be done, bonding is used to join two or more PVC parts. Bonding makes use of PVC-friendly adhesives for joining. Because it is nondestructive, it is generally used for joining small parts where joints would be visible if joined via welding.

Properties of Type 1 PVC:

As type 1 PVC is manufacturing using UV stabilization method, it has good resistance against UV rays. This makes it perfect for exterior use, especially in applications where sun exposure is guaranteed. Other properties of type 1 PVC are:

Highly Resistance Against Fire: 
Type 1 PVC is extremely fire-resistant, hence it makes for good fireproofing material for use in different scenarios such as PVC pipes. Electrical insulations, wall dividers etc.

Extremely Hard: 
Type 1 PVC is hard enough to be used as exterior material. Well-made PVC components last long and don’t lose their shine or colour with time as easily as other plastics due to their high tensile strength.

Electrical Insulation: 
PVC is chosen as wire insulator not just because of their fire-resistant properties, but also because they are poor conductors of electricity, providing good electrical insulation.

Commercial Applications of Type 1 PVC:

Due to their high performance and good resistance properties, they are used in various applications such as:

  • Ø  Cabinets for bathrooms and kitchen
  • Ø  Plastic nuts, bolts and binding apparatus
  • Ø  Covering sheets for exterior protection
  • Ø  Electric wire insulator
  • Ø  Frames for windows, doors and skylights
  • Ø  Plumbing pipes
  • Ø  Filters
