Why is pvc thermoplastic

Polyvinyl Chloride is available in filament form as a plastic welding rod the material used for welding , but it is not presently retrofit for specific use in 3D printing. Although there are a growing number of plastics and plastic substitutes available for 3D printing , by far, the two most common are still ABS and PLA.

The biggest issue with PVC for 3D printing is its corrosive nature potentially compromising typical machines' functionality if it were used over a longer period. An interesting kickstarter developed a PVC capable 3D printing nozzle extruder head put forward by engineer and entrepreneur Ron Steele that unfortunately closed without enough interest in You can take a look at the introductory pitch video here:.

Polyvinyl Chloride can be cut on a CNC machine , but any machinist who has tried has probably experienced degradation in the cutter depending on the material it is made. PVC is corrosive and abrasive, and cutters that are not made from stainless steel or a comparably corrosive resistant material are likely to deteriorate over time.

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. Accordingly, shops need to be equipped with good ventilation systems. Those that aren't are likely to be hesitant to work with the material. Additionally, unique corrosive resistant materials like stainless steel or chrome plating are required for the mold tool when injection molding PVC plastic. Shrinkage in PVC tends to be between one and two percent. It can still vary based on several factors, including material durometer hardness , gate size, holding pressure, holding time, melt temperature, mold wall thickness, mold temperature, and the percentage and type of additives.

PVC can pose a health hazard when burned as it emits hydrogen chloride HCl fumes. In applications where the likelihood of fire is high, PVC free electrical wire insulation is sometimes preferred. Fumes can also be emitted when melting the material such as during prototyping and manufacturing processes like 3D printing , CNC machining , and injection molding.

We recommend taking a look at the Material Safety Data Sheets MSDS for different chlorinated hydrocarbon gases like chlorobenzene and discussing the production process with a professional manufacturer. PVC provides industries with a series of critical advantages that have cemented its place as one of the most popular and widely used plastics on the market. These advantages include:. PVC's advantages helped solidify its place as one of the most used plastics around the world. However, even though it's widely effective and popular, you have to consider some factors when using the material.

While PVC has a host of advantages that make it a desirable material to work with, there are some reasons to take caution. The disadvantages that you have to account for when using PVC include:. Examples include vinyl siding, gutters, and drainpipes. PVC and also be made in flexible forms by adding a plasticizer which is an additive to increase fluidity often phthalates are used. Flexible PVC is used in hoses, tubing, and electrical insulation.

In addition PVC is fire resistant due to the chlorine component making it an ideal construction component. The excellent electrical insulation of PVC makes it well-suited for use in cabling. PVC doesn't corrode, is chemically stable won't de-polymerize and has a high impact strength. For custom extrusion of PVC or other plastics contact us to learn how we can assist you.

Polyvinyl Chloride structure [2] PVC is a white, brittle solid available in powder form or granules, formed through an addition polymerisation reaction between vinyl chloride monomers Figure 1. Processing of PVC PVC resin obtained from the above processes is extremely unstable due to low thermal stability and high melt viscosity.

At KEP, we manufacture a wide range of TPE tubing following stringent quality standards that is a top choice for industries including medical and surgical, food and beverage industries, and others.

Common applications include fluid pathway systems for doctor offices, dental offices and hospitals, dairy and beverage tubing, resistance tubing for exercise, and solutions for distribution and industrial applications. Another nonallergenic alternative to natural rubber latex, common uses of PVC tubing include many of the same tubing applications as TPE, like beverage transfer and dairy processing. With outstanding clarity, flexible PVC tubing is a good choice for medical applications that rely on easy viewing of water and fluid lines.

Flexible PVC tubing is also ideal for laboratory and research applications, among others. Whether you want to re-engineer a product to reduce cost or modify performance, or you have a prototype for a completely new product you want to manufacture, KEP is ready to take on your challenge.
