Polyvinyl siloxane (PVS), also called poly-vinyl siloxane, vinyl polysiloxane (VPS), or vinylpolysiloxane, is an addition-reaction silicone elastomer (an addition silicone). It is a viscous liquid that cures (solidifies) quickly into a rubber-like solid, taking the shape of whatever surface it was lying against while curing.
Decamethylcyclopentasiloxane, or D 5, a cyclic siloxane. The word siloxane is derived from the words silicon, oxygen, and alkane. In some cases, siloxane materials are composed of several different types of siloxane groups; these are labeled according to the number of Si−O bonds: M-units: (CH 3) 3 SiO 0.5, D-units: (CH 3) 2 SiO, T-units: (CH ...
The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxane is linear polydimethylsiloxane (PDMS), a silicone ...
Materials may react violently with water or form peroxides upon exposure to air (e.g., potassium, sodium). 1. Materials that are normally stable but can become unstable (self-react) at high temperatures and pressures. Materials may react non-violently with water or undergo hazardous polymerization in the absence of inhibitors (e.g., propene). 0.
In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed.This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.
Declare Product Label. Declare is a product labeling program that relies on the LBC Red List as its primary basis for material evaluation. [5] In creating a Declare label for a product, a manufacturer must disclose all of that product's intentionally added constituent chemicals to the designated 100 parts per million (ppm) reporting threshold.
The three basic categories of vinyl sheet flooring are homogeneous, inlaid, and layered composite. Vinyl flooring differs in manufacturing process and polyvinyl chloride content. [5] Composite manufacturing begins with a fibrous backing sheet. This was often felt or paper (before 1980, often with asbestos [6]); more modernly, it is generally ...
They are typically used as coatings, adhesives, and molding materials. [1] "Formvar" used to be the registered trade name of the polyvinyl formal resin produced by Monsanto Chemical Company in St. Louis, Missouri. That manufacturing unit was sold and formvar is now distributed under the name "Vinylec". [2]
