uPVC or PVCu is a form of plastic and stands for unplasticised polyvinyl chloride. It is also known as rigid PVC due to the fact that it is hard and not flexible. It is a resistant from of PVC that is often used for pipework and window frames.

Polyethylene and polyvinyl chloride, or PVC, are both plastics that form through a mechanism called radical polymerization. The reaction conditions used for each are different, as are the structures, properties and uses of the finished materials.

PVDF membranes are extremely hydrophobic which may hinder movement of aqueous buffer and protein binding in the membrane during membrane transfer. So, PVDF membrane is hydrated with 100% methanol to facilitate effective transfer.

A WPC vinyl product is manufactured with a wood-plastic composite backing instead of a solid PVC backing. The engineered backing combines recycled wood pulp and plastic composites to form a bond of strength and stability. This is then topped with a standard vinyl top layer.

PVDC was even contained in the packaging. But, in a bold decision to favor public health and the environment over profits, Johnson chose to eliminate PVDC from Saran Wrap — even knowing it would hurt both performance and sales.

PVC flooring or polyvinyl flooring is none other than alternative terms for vinyl flooring! PVC stands for polyvinyl chloride, which is the material that makes up vinyl flooring. Thus, it is often shortened to polyvinyl flooring or simply, vinyl flooring, the most common term for this particular floor covering.

PVD (physical vapor deposition) In a nutshell, this is considered bad for fresh piercings, and arguably for healed piercings too. This method of coloring jewelry consists of thin films of a material being applied to the jewelry via a vacuum deposition process.

PVDF membranes are naturally hydrophobic but are modified to a hydrophilic nature. Useful for a wide range of applications, both aqueous and non-aggressive solvent-based. These membranes are typically low protein binding and are frequently used for sterilizing filtration.

PVC Wall and Ceiling Panels Duramax is a water-resistant wall and ceiling panel that is used for wet environments, cleanrooms, and areas that require hygiene. As an affordable alternative to Fiber Reinforced Plastic (FRP) panels, it eliminates the need for Oriented String Board (OSB) backing panels.

Vinyl is commonly used as a shorthand name for polyvinyl chloride (PVC) plastic as used in a range of products from flooring to siding to wall covering.

PVC has a very low thermal stability and stabilizers help prevent degradation of polymer during processing or exposure to light. When subjected to heat, vinyl compounds initiate a self-accelerating dehydrochlorination reaction and these stabilizers neutralize the HCl produced enhancing the life of polymer.

Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic. It is made softer and more flexible by the addition of plasticizers. If no plasticizers are added, it is known as uPVC or Rigid PVC (Food Safe PVC). uPVC or Rigid PVC does not contain any phthalates or BPA and is safe and stable.

Calico-TiAlN is applied using lateral rotating cathode technology in a PVD (physical vapor deposition) process. Material is vaporized from a solid source in the form of atoms/molecules and then transported in the form of a vapor through a vacuum, low pressure gas/plasma to the substrate where it condenses.
