How Are Polymers Created? . Indeed, polyethylene – which can constitute a chain of up to 10,000 monomers – is a translucent and thermoplastic material that is often used to make plastic bottles, containers and packaging. Polypropylene, on the other hand, is harder than polyethylene (with up...
Polyamide fabric is a general term that is used to refer to a variety of different fabrics that are made from strings of polyamide monomers. The most famous form of polyamide fabric is nylon, but there are quite a few different varieties of this textile.
In addition, material, platform and software solutions are enabling companies to overcome significant hurdles related to batch-to-batch and machine-to-machine repeatability. This makes it possible to reduce the time and cost associated with set-up and change-over which enhances the manufacturing syste...
While polyurethane polymers are used for a vast array of applications, their production method can be broken into three distinct phases. First, the bulk polymer product is made. Next, the polymer is exposed to various processing steps. Finally, the polymer is transformed into its final product ...
These polymers are usually solid after they are reacted, and they are then melted and forced through spinnerets to make polymer strands. Once these strands have cooled, they can be loaded onto spools and shipped to textile manufacturing facilities to be made into mesh fabric. In most cases,...
A variety of raw materials are used to produce stretchable spandex fibers. This includes prepolymers which produce the backbone of the fiber, stabilizers which protect the integrity of the polymer, and colorants. Two types of prepolymers are reacted to produce the spandex fiber polymer back-bone...
How Polymers Improve Concrete Floors - Possibilities Today and Prospects for the FutureIndustrial floors are required to resist extreme environmental stresses. The planning and the installation are therefore not easy tasks. Unnecessary damage is an all too common result. A properly dimensioned and ...
The parallel composite fibers currently developed are mainly parallel composite fibers such as PBT/PET and CDP/PET. PBT and PET are both polyester polymers with very similar macromolecular structures. They have good compatibility and adhesion and can be made into parallel composite fibers without peeli...
Polyethylene (PE) is made by the reaction of multiple ethylene molecules in the presence of a catalyst to break the double bond and connect the carbon atoms into a chain. The longer the chain, the higher the molecular weight. Polymers can have molecular weights in the millions. Uses ...
Next, these monomers are transformed into polymers with polyvinyl chloride resin. The PVC used in artificial leather production must be flexible, so manufacturers add plasticizers this petroleum product to make it bind to the base fabric used in ersatz leather production. The process used to ...
