Introduction Polymers. They’ve put a lot of bulky metal, glass, and stone out of work since they came on the scene in a big way back in the 1950s. These materials have definitely become more complex since that first Tupperware™ container emerged from
Diluents (Fillers) Diluents, also known as fillers, are used to bulk up the formulation when the active ingredient is present in small quantities. They help achieve the desired tablet size and weight. Common diluents include: Lactose Microcrystalline cellulose Dicalcium phosphate Mannitol Specialized Ex...

PCC and GCC are used as fillers in polymers such as polyethylene, polypropylene and polyvinyl chloride. They help make plastic parts opaque, but they don’t interfere with polymer colorants. PCC improves stiffness and impact in polypropylene and adds impact strength to rigid polyvinyl chloride for ...
(a) What are fillers and reinforcing agents? (b) What is their purpose? Describe any practical advantages lead has for its use in x-rays absorption. What is Anomeric effect? Explain with example. Explain the role of nuclei in cloud development. ...
Resin, in its broadest definition, refers to a viscous substance of plant or synthetic origin that is typically convertible into polymers. Such resins, when derived from plants, are known for their sticky composition and aromatic qualities, often used in products like varnishes, adhesives, and ince...
RTV-2 would typically comprise silicone linear polymers, reinforcing mineral fillers or silicone resins, a crosslinker, a catalyst, and an inhibitor to control the pot life of the mix, so that it can be processed. Crosslinking is initiated by mixing the two components and occurs by condensation...
This substance is used in the following products: lubricants and greases, metal working fluids, polymers, metal surface treatment products, coating products, non-metal-surface treatment products, fillers, putties, plasters, modelling clay, hydraulic fluids, inks and toners, laboratory chemicals, paper...
One of the primary functions of gum base is to provide chewiness. The unique blend of polymers, resins, and fillers creates a resilient texture 1that can withstand continuous chewing. This chewiness is what sets gum apart from other confections. ...
The main components of UV ink are polymerized prepolymers, photosensitive monomers, and photoinitiators, and the auxiliary components are colored pigments, fillers, additives (leveling agents, defoamers, polymerization inhibitors), etc. 1. Polymer prepolymer is an important component that determines the...
